The sexual dysfunction is mainly manifested by hyposexuality, stiff and powerless, impotence, premature ejaculation and the like, which causes great mental stress to patients. At present, the average age of patients is younger and younger, and the psychological, physiological health and happiness indexes of people are threatened.

In the study related to sexual function, besides the detection of testosterone content and sex organ or adnexal organ weight, the sexual function identification experiment is more intuitive. The mouse mating experiment is a commonly used sexual function identification experiment, namely, a male mouse and a female mouse in estrus are subjected to 1:1 caging, the capturing, striding, inserting and ejaculation behaviors of the male mouse are observed within 20-30min under a quiet environment, the capturing, striding, inserting latency and times, the ejaculation latency and the interval after ejaculation are recorded, and the sexual activity of the male mouse is judged according to the results.

Because mice prefer to live in a quiet environment with dark light and live at night, and the mice are bred by following each other, in a mouse mating experiment, experimenters need to provide the mice with a dark and comfortable environment. At present, can provide the better experimental condition for this experiment be open field experimental box, but open field experimental box general area is great, and the open unsuitable mouse mating of space is caught, and shoots the record angle and be vertical horizontal face downwards, is difficult to catch mouse mating action, has the observation dead angle easily.
