MALES
Testes: they are oval shaped structures that produce the male gametes and sex hormone called testosterone.
Seminiferous tubules: tubules where spermatogenesis occurs.
Vas deferens: are tubules which lead to the epididymis.

Uterus: has an inner layer called endometrium which becomes folded and vascularised to allow implantation. The endometrium nourishes the embryo..
Cervix: is a muscular ring between the uterus and the vagina. It secretes a plug of mucus, which prevents entry of pathogens and air
The vagina is a muscular copulatory canal into which penis enters. Vagina also allows passage of foetus during parturition.
