2021-05-30 17:51:59 Very Important Points - Human Reproduction

Orchiopexy : When the undescended testes are brought into scrotal sac by surgical process during childhood
this process called as
orchiopexy.

Cutting of the vasa-deferens and ligation is termed as vasectomy.

Erection of penis is controlled by parasympathetic nervous system.

Ejaculation of semen is controlled by sympathetic nervous system.

Longest unstripped muscles of the body are found in the walls of uterus. (During pregnancy)

Clitoris is a homologous to the penis in the male.

Bartholin Glands : It is homologous to Cowper's gland of male

A functional mammary gland is characteristic of all female mammals.

The milk produced during the initial few days of lactation is called colostrum which contains antibodies (IgA)
absolutely essential to develop resistance for the new-born babies. Open / Comment
