Male reproductive system

The testes in humans are situated outside the abdominal cavity inside a pouch called scrotum. The purpose served is forSpermatogenesis requires a temperature slightly lower than the normal internal body temperature.
The scrotum keeps the testes outside the abdominal cavity and helps in maintaining their temperature about 2–2.5 $^\circ C$ lower than the internal body temperature.
At the normal body temperature of the abdomen, sperm formation would be impaired.
The other suggested purposes (display of sex, avoiding compression, space for the epididymis) are not the reason for this position.
Hence the purpose is maintaining the scrotal temperature lower than the internal body temperature. -
If for some reason the vasa efferentia in the human reproductive system get blocked, the gametes will not be transported fromThe male accessory ducts are the rete testis, vasa efferentia, epididymis and vas deferens.
Path of sperms: seminiferous tubules → rete testis → vasa efferentia → epididymis → vas deferens → ejaculatory duct → urethra.
The vasa efferentia leave the testis and open into the epididymis, which lies along the posterior surface of each testis.
If the vasa efferentia are blocked, sperms cannot pass from the testis to the epididymis.
Hence the gametes will not be transported from testes to epididymis.
That is every question in Human Reproduction for this filter.
