This application is a whole-contents divisional application from New Zealand Patent Application No 525677.

TECHNICAL FIELD This inventionrelates generally to the field of insemination of mammals. Specifically, it relates to systems to achieve insemination which may be particularly applicable once sperm have been treated or processed in some manner, such, as sorting the sperm through flow cytometry. More particularly, the invention may relate to systems to achieve insemination, 10 with a low number of spermatozoa as compared to conventional artificial insemination, through hy steroscopic insemination techniques. The inventionmay be particularly applicable to systems for inseminating equids, bovids and swine. Furthermore, the invention may be particularly applicable to sex selection of offspring in mammals.

BACKGROUND Artificial insemination (AI), in various forms, has been used to achieve successful rates of pregnancy and resulting offspring in mammals. Traditional forms ofAI include various in vivo technologies such as conventional intrauterine artificial insemination techniques, ormore particularly, trans cervical artificial insemination. Natural insemination doses may typically be large. For example, in some species, natural insemination may involve sperm numbers on 20 the order of2-20 x 109 sperm. In contrast, conventional AI techniques in the same species may require sperm numbers on the order of200-500 x 106 sperm. This can still be viewed as a large number of sperm, especially if the sperm are processed in some manner. Given the traditional requirements for high numbers of sperm to achieve acceptable numbers of pregnancies, other insemination techniques have been sought to address developing breeding 25 technologies that may result in a lower sperm count for subsequent insemination. Low dose insemination has been particularly discussed in the PCT publication WO 99/33956, entitled "Sex-Specific Insemination ofMammals WithLowNumber of Sperm Cells." Hysteroscopic insemination has been proposed and to some extent discussed in Morris et al., 2000, hereby incorporated by reference. la It should be preliminarily noted that all references mentioned in this application, and including additional reference not mentioned, are listed at the end of this 'written discussion, all of which should be considered as incorporated by reference.

High-speed sperm sorting using flow cytometry has been used successfully as a 5 breeding technology to produce offspring in mammals, such as horses, cattle, sheep, rabbits, pigs and humans. It can potentially be used for several other species as well. Technologies have been developed to enhance or modify the pregnancy and resulting offspring of mammals, One potential limiting factor in optimizing the success of artificial insemination, as 10 recognized in Pickett et al., 1989, may be inseminating with low numbers of spermatozoa. Pickett et al. recognized that a potential minimal recommended dose for conventional artificial insemination in the mare may be as high as 500 x 106 progressively motile sperm. With low sort rates of around 700 spermatozoa per second in some sperm sorting technologies, it may take several days to obtain the recommended dose of spermatozoa for artificial insemination. 15 This may not only be impractical, but the viability of the spermatozoamay also be significantly reduced. Low-dose insemination techniques, therefore, may be a desirability to those skilled in the art to potentially reduce the number of spermatozoa needed for acceptable fertility rates.

Additionally, what might be considered low doses for insemination may not typically result in acceptable fertility rates. Fertilily rates may be considered acceptable or statistically 20 comparable, for example, if they are achievable over a high sample size, range or percentage of the fertility rates resulting from conventional AI. Low-dose insemination techniques, therefore, may be a desirability to those skilled in the art to potentially reduce the number of spermatozoa needed to maximize fertility.

Whether in consideration of low-dose insemination or to improve AI fertility rates 25 generally, an additional concern regarding artificial insemination is the efficiency of the procedure as a whole with regard to the resulting numbers of pregnancies. A number of 2 procedural steps may have been used in conventional Al procedures, such as the synchronization of estrus in breeding mares; the preparation of the insemination dose, more particularly the use of extenders for the dilution (Kenny et al., 1975) and resuspension of spermatozoa (using TALP or HEPES-bufferedTyrode's Medium, for example), centrifuging 5 the sample through a density or viscosity gradient (using PERCOLL or the like); assessing viability or motility; and the particulars of the insemination procedure. Insemination procedures have historically included ultrasound and rectally-guided techniques. Hysteroscopic insemination of mares has also been conducted, as described in the Vasquez et al., 1998 and Manning et al., 1998 references. Only limited success, however, has been 10 demonstrated in utilizing the above described procedures in conventional AI and in the Vasquez et al. and the Manning et al. procedures. In particular, neither reference may have produced statistically comparable conception rates to conventional AI. In particular, the Vasquez et al. and the Manning et al. references may have demonstrated conception rates of 33% for 3.8 x 106 spermatozoa and 22% for 1.0 x 106 spermatozoa, respectively, which may 15 be considered non-comparable conception rates relative to conventional AI for the species involved. Despite the previous and substantial attempts at producing an efficient procedure for AI, heretofore, a long felt but unsatisfied need for an efficient procedure for the hysteroscopic inseminationofmammalshas existedinbreedingtechnology. Furthermore, and given the traditional requirements for high numbers of spermatozoa to achieve acceptable 20 numbers of viable pregnancies, as described above, a need for efficient, low-dose hysteroscopic insemination has heretofore existed in current breeding technology.

Furthermore, deep intra uterine insemination of swine has been conducted, as described in the Vasquez et al., 2000 reference. However, insemination was conducted with what might be considered a high number of spermatozoa, on the order of 20 x 107 25 spermatozoa. However, Vasquez et al., 2000, may have identified the long felt but unsatisfied need for an insemination procedure to address breeding technologies utilizing lower spermatozoa numbers for insemination, such as may result from current sperm sorting technologies.

Therefore, as may have been demonstrated from the Vasquez et al., 1998, Vasquez 3 et al., 2000, and Manning et al., 1998, references, those skilled in the art may have failed to address the identified need for providing an insemination technique potentially resulting in high fertility rates in mammals and the resulting high production in mammals, high fertility rates for low insemination dosages, and insemination techniques to address issues of efficaciousness, 5 particularly with regard to the hysteroscopic insemination technique.

One important procedural step with regard to insemination procedure, generally, is the establishment of a insemination dose containing desirable numbers of viable and motile spermatozoa to potentially provide higher fertility rates. Procedures for the selection of motile spermatozoa may have been conducted with regard to conventional AI, for example 10 in the reference Gremdahl et al., 1996 and in hysteroscopic insemination generally, by establishing adensity or viscosity gradient utilizing, for example, PERCOLL (Sigma Chemical Co., St. Louis, MO) alone or in combination with other substances. However, heretofore the substantial efforts to fractionate viable or motile sperm have not particularly addressed the identified needs for an insemination technique potentially providing high fertility rates, high 15 fertility rates for low insemination dosages, and insemination techniques to address issues of efficaciousness, particularly with regard to the hysteroscopic insemination technique.

A second potential issue with regard to insemination procedure, generally, is the establishment of a insemination dose containing desirable numbers of viable and motile spermatozoa to potentially provide higher fertility rates without a particular motility test, as 20 described above. The introduction of a density or viscosity gradient may introduce a stress to the spermatozoa that may actually reduce the actual number of viable and motile spermatozoa available from a particular sample. Heretofore, the substantial efforts to fractionate viable or motile sperm have not particularly addressed the identified needs for an insemination technique providing for high fertility rates, high fertility rates for low 23 insemination dosages, and insemination techniques to address issues of efficaciousness, particularly with regard to the hysteroscopic insemination technique. In fact, due to the potential for reduction in the total number of viable or motile sperm from a particular inseminate sample, previous attempts incorporating a density or viscosity gradient may have actually taught away from the present procedure of providing for an insemination technique 4 which may require less efforts to obtain a viable, low-dose insemination sample.

A third potential issue with regard to insemination procedure, generally, is the establishment of a compatible volume for the particular insemination technique. One recognized need, as described above, is the desire to potentially provide higher fertility rates.

A second recognized need, also described above, is the ability to use low numbers of spermatozoa to potentially achieve high fertility rates. The insemination dose volume may be determined by the particular insemination technique. However, the dose volume may contain a desirable number of spermatozoa to potentially provide for a higher rate of fertility. Substantial attempts have been made to establish an appropriate insemination technique that 10 would allow for the appropriate number of spermatozoa, given the potential volume requirements of the insemination technique, to potentially provide acceptable fertility rates. However, determining a compatible insemination dose volume for a particular insemination technique, to further potentially provide higher rates of fertility, has potentially not been established for hysteroscopic insemination, as the reported fertilily rates in Vasquez et al. and 15 Manning et al. may demonstrate.

Additionally, and as previously mentioned, the sperm sample may be processed prior to the insemination procedure. Conventional AI, for example, may provide for the use of extenders for the dilution (Kenny et al., 1975) and resuspension of spermatozoa. However, the particular media used may not be compatible with the insemination procedure itself. 20 Incompatibility of the sample media may result in lower deposition numbers of spermatozoa or dose volume or a lower fertility rate. Furthermore, the mode or form of the deposited insemination dose or the particular method of deposit during AI may further affect the number of deposited spermatozoa available for conception. However, heretofore the substantial efforts directed toward insemination media may have not particularly addressed the need for 25 providing an insemination technique potentially resulting in high fertility rates, high fertilily rates for low insemination dosages, and insemination techniques to address issues of efficaciousness, particularly with regard to the hysteroscopic insemination technique.

An additional factor to consider is the timing of insemination. Insemination timing may be an important factor, for example, to sperm viability and longevity and the timing of the estrous cycle of the mammal. Particularly at issue might be the distant location of sperm sample acquisition (i.e. the location of the male mammal) and ultimate location of the Al. Previous efforts may have been made in conventional AI to preserve the sperm sample prior 5 to insemination and to coordinate the insemination with the estrous cycle. However, heretofore the substantial efforts directed to insemination timing may have not particularly addressed the identified needs for, and may have even failed to understand the problems of, providing an insemination technique potentially resulting in high fertility rates, high fertility rates for low insemination dosages, and insemination techniques to address issues of 10 efficaciousness, particularly with regard to the hysteroscopic insemination technique.

The source of the sperm sample may also be of importance to the resulting insemination. Epididymal acquisition of the sperm sample (obtaining sperm sample from the epididymis of the testis; ductules emerging posteriorly from the testis that holds sperm during maturation and that forms a tangled mass before uniting into a single coiled duct which is 15 continuous with the vas deferens) may provide some inherent advantages as to timing of the insemination and viability of the sperm. However, heretofore the substantial efforts directed to sperm source, viability and insemination timing may have not fully addressed the identified needs for, and may have even failed to understand the problems of, providing an insemination technique potentially resulting in high fertility rates, high fertility rates for low insemination 20 dosages, and insemination techniques to address issues of efficaciousness, particularly with regard to the hysteroscopic insemination technique.

DISCLOSURE OF THE INVENTION The present inventors have recognized the potential problems associated with conventional methods of artificial insemination. Accordingly, embodiments of the present 25 invention may provide for the production of a mammal through the use of artificial insemination that may address inadequacies of previous insemination techniques and systems. The invention may comprise, according to particular embodiments, a method of producing a mammal whereby potentially high fertility rates may be accomplished, fertility rates which may 6 be statistically compatible with conventional AI results, and potentially high fertility rates with the use of low spermatozoa doses. More particularly, embodiments of the present invention may provide for the production of a mammal through the use of hysteroscopic insemination techniques. Additionally, the present invention may comprise embodiments particularly 5 directed at mammals such as equids, bovids, and swine, among other mammals. Embodiments of the present invention, therefore, may even be considered development away from previous efforts of artificial insemination.

An object of the present invention, therefore, is to provide for the production of a mammal utilizing an efficacious procedure, or at least provide the public with a useful choice. The present invention provides a technique of 10 artificial insemination for mammal production such that lower numbers of spermatozoa may be used in the insemination dose relative to conventional AI and other insemination techniques, while, in particular embodiments of the invention, at least statistically comparable success rates in fertility are maintained.

The present invention provides for the production of a mammal utilizing an artificial insemination procedure that may potentially achieve high fertility rates consistent with lower spermatozoa production from breeding technologies such as sperm sorting. The present invention, therefore, provides a technique of artificial insemination for mammal production that achieves statistically comparable success rates in 20 fertility, compared to conventional AI and other insemination techniques, with lower-doses of spermatozoa.

Furthermore, an object of the invention is to provide for the production of a mammal utilizing an artificial insemination procedure that may enhance steps involved in the artificial insemination. To this end, certain embodiments provide a technique of 25 artificial insemination for mammal production such that steps of estrous cycle timing, spermatozoa source, viability, longevity and processing, insemination dose media and volume, and insemination timing may be optimized, particularly for low-dose insemination and potentially high fertility. intellectual property office ] ofni.

Estrus may be defined as a state in which the female mammal is capable of conceiving and estrous cycle may be defined as the 5 correlated phenomena of the endocrine and generative systems of a female mammal, potentially from the beginning of one period of estrus to not later than the beginning of the next. In accordance with a preferred embodiment, estrus may be induced, and for multiple female mammals synchronized, by administering a substance such as aprogestagen, preferably for mares altrenogest, and preferably 10ml orally, potentially for 10 consecutive days, 10 followed by 250 [ig cloprostenol i.m., potentially on day 11. Furthermore, a female mammal may be induced into ovulation at the time of insemination. Ovulation may be induced, and in preferred embodiments, by the administration of 3000 iu human Chorionic Gonadotropin (hCG, Chorulon, Intervet, Inc., Millsboro, Holland), preferably administered intravenously at the time of insemination or up to approximately 8 hours previously. Ovulation may even be 15 induced, in preferred embodiments, by the administration of from about 2000 to about 5000 iu human Chorionic Gonadotropin In preferred embodiments, estrous cycles may be synchronized by administering a synthetic progestagen altrenogest (0.044mg/kg p.o., Regumate; Hoechst Roussel Vet, Warren, New Jersey, USA) daily for 10 consecutive days.

A time when the female mammal is appropriately fertile may be determined. The ovaries may be examined, and in preferred embodiments examined ultrasonographically, and 25 preferably every second day until a follicle, and in accordance with preferred embodiments a dominant follicle, preferably of > 30mm diameter, is detected. The female may be examined until a follicle, preferably pre-ovulatoiy, of preferably > 35mm is detected. In one embodiment, the female may be inseminated during the same day as estrous inducement or synchronization, the same day as ovulation inducement or synchronization, or the same day 12 as estrus and insemination inducement or sychronization.

Next, in accordance with particular embodiments ofthe invention, the guide element, and in preferred embodiments the optical element (12), may be vaginally inserted into the female. Furthermore, the catheter (2), and in preferred embodiments the reservoir element, 5 may be inserted into the female. Thesequenceofinsertionoftheopticalelement(12)andthe catheter (12) may be sequential or coincidental in time.

The guide element or optical element (12) and the catheter (2) may then be guided through the vagina (20) of the female, as depicted in Figure 2. In accordance with one embodiment, the optical element (12) and catheter (2) may be manually guided. In fact, the 10 catheter (2) may be manually guided without the optical element (12). However, accuracy in finding the UTJ and the potential result in increased fertilily rates, particularly for low numbers of sperm and overall potential efficacy in the procedure, may require a more accurate guidance procedure. In preferred embodiments, the optical element or endoscope, preferably a flexible endoscope, in preferred embodiments having dimensions of 1.6 m long with an outer 15 diameter of 12 mtn] may be guided through the cervix (22) and propelled forward through the uterine lumen (24), or in additional embodiments, through a uterine horn of the female of the species. An added benefit of the use of the videoendoscope can be lack of a need to rectaily guide the insemination process, as may have been required in past efforts by those of skill in the art The uterotubal junction (UTJ) (30) of the female mammal may then be located, preferably optically with the optical element (12). The catheter (2) may then be positioned in the vicinity of or proximate to the uterotubal junction. In accordance with preferred embodiments, the endoscope may be directed under visual control along the uterine hom (26) ipsilateral to the ovary containing the pre-ovulatory follicle (28). Preferably the tip of the 25 endoscope may be directed proximate to, and in preferred embodiments within about 3-5 cm of said uterotubal junction, and in preferred embodiments within about 3-5 cm ofthe papilla (32) of the uterotubal junction. 13 WO 02/28311 PCT/US01/02304 At least a portion of the artificial insemination sample may then be extruded from the catheter (2). In accordance with preferred embodiments, the outer cannula (10), followed by the inner GIFT catheter (2) containing the sperm suspension, may be extruded from the working channel of the endoscope until the tip of the GIFT catheter touches the uterotubal 5 junction, and in preferred embodiments, touches the papilla. In accordance with alternative embodiments of the present invention, a portion or at least a portion of the artificial insemination sample may be aspirated during extrusion from the catheter, thereby potentially creating an aspirated sample. Such aspirated samples should be understood to include bubbled samples and frothed samples. An aspirated sample may not only provide better adherence to 10 a surface in the vicinity of the UTJ, but may further allow for improved fertility rates. Furthermore, an embodiment of the present invention provides ahysteroscopic insemination element comprising a uterus of a female species of a mammal, a plurality of sperm cells contained within said uterus, and an aspirated volume of media surrounding or interspersed with the sperm cells and to which the sperm cells are responsive. Such alternative 15 embodiments should be construed as disclosed with regard to all embodiments ofthe present invention, either in single or in combination, and should be construed to be disclosed as such.

A low number of sperm may be deposited in the vicinity of the uterotubal junction. In accordance with preferred embodiments, a plunger of the syringe (4) may be depressed to deposit the sample, and in particular embodiments, a small volume (preferably perhaps 20 ~100(il) of the sample, preferably onto the surface of the papilla. The guide element, and in preferred embodiments the optical element (12), and the catheter (2) may be withdrawn from the uterus ofthe female mammal. In accordance withpreferred embodiments, filtered air may be introduced within the uterus of the female to facilitate passage of the instruments through the uterine lumen. Furthermore, in accordance with preferred embodiments, the filtered air 25 may be evacuated from the uterus, preferably simultaneous to the withdrawal of the optical element (12) and catheter (2).

The placing of a low number of sperm may be accomplished, in one preferred embodiment of the invention, by placing with the catheter (2) a number of sperm, preferably 30 numbers selected from: less than about ten million sperm, less than about five million sperm, 14 less than about two million sperm, less than about one million sperm, less than about five hundred thousand sperm, and less than about one hundred thousand sperm.

Subsequently, the fertilization of an egg of the female may occur and the production of an offspring mammal from the fertilized egg. In accordance with preferred embodiments 5 of the invention, success levels of fertilization may be statistically comparable to a conventional uterine body artificial insemination process. Statistically comparable success levels may be defined as fertilization rates of at least about 75% success rates, at least about 65% success rates, at least about 60% success rates, at least about 50% success rates, at least about 45% success rates, 10 and at least about 90% of a success rate practically experienced with conventional AI for any particular species. Furthermore, success levels for the present invention may be statistically comparable to a conventional uterine body artificial insemination process over a sample of cumulative fertilizations which is greater than about 100, which is greaterthan about 500, and which is greater than about 1000. Success rates may further statistically provide for at least 15 a confidence level of at least about 95 percent confidence (potentially expressed as P> or equal to about 0.05), therefore potentially being statistically comparable with conventional AI. Additionally, success rates for the present invention may potentially have the same P value over arange of differing spermnumbers, potentially such as l,5or lOx 106 sperm for equine. Furthermore, a success level or rate may be expressed in terms of sample size, whereby the 20 present inventionmay provide, in preferred embodiments, any ofthe aforementioned success rates over a power calculation ((3) of at least about 80 percent. Additionally, the success rates, in preferred embodiments, given particular insemination doses for sex-sorted stallion spermatozoa, may even apply to a low number of spermatozoa and may routinely produce fertility rates of at least about 90% of those rates resulting from conventional artificial 25 insemination for a species. Additionally, according to particular embodiments of the present invention, the previous success rates may even be achieved for species of mammal such as bovids, equids, and swine.

In regard to sperm viability, longevity and mobility, for example, the present invention may provide for establishing an artificial insemination sample utilizing fresh sperm. The term "fresh sperm" may be broadly defined as sperm that has not been treated, processed or preserved in any manner such that the sperm viability, longevity and/or mobility might be compromised. Such treatment, processing or preserving may include, for example, the sorting of sperm, the freezing and subsequent thawing of sperm, the dilution and resuspension of 5 sperm, and motility and viability testing or separation, generally, and in particular, Percol1 gradient processing. The use of fresh sperm in accordance with embodiments of the present invention herein may permit the use of low numbers of sperm for insemination even, for example, when using poor quality collected semen.

Additional embodiments may provide Hie step 15 ofcentrifuging the sperm through density gradients, and in preferred embodiments a Percoll gradient A potentially preferred embodiment may use a 90:45% Percoll gradient An additional embodiment may comprise limiting the concentration to less than about twice the starting concentration. Implementation of the Percoll gradient should be understood to encompass the use ofPercoIl pie or postprocessing ofthe sperm, and in particular, potentially 20 pre or post sorting. Therefore, in accordance with embodiments herein, the Percoll gradient procedure may be used with "fresh sperm." The sample established from the desired or selected sperm cells may be used to establish the artificial insemination sample, potentially increasing the fertility rates due, at least in part, to the potentially higher rate of viability of the sample. The Percoll gradient procedure in accordance with the present invention may be 25 conducted in conjunction with the use of lower numbers of sperm placed within the depositing catheter, as more particularly described supra.
