Document Summary

Males scrotum within them: gonadal ridges have developed into testes; testes descend into the, scrotum: sac-like structure; holds the paired testes and the sperm cells. The slightly higher core body temp would kill the sperm cells. From exercise) won"t harm the sperm cells: once germ cells are in the gonadal ridges, the new formed testes start secreting testosterone, testosterone release. Helps mesonephric ducts differentiate into the structure of the male anatomy. Mesonephric ducts are attached to the gonadal ridges and when the gonadal ridges go down, they take the ducts with them. Ducts must degrade in males or they will develop both female and male reproductive systems in the male body. Paramesonephric ducts differentiate into the female reproductive system. Uterine tubes, uterus, vagina: individuals with some male and some female anatomy form if hormones aren"t released at the same time or at the correct concentrations. Usually only part of one of the system forms.
