3.	placenta	4.	all of the above

The menstrual bleed is basically due to the withdrawal of:

2. LH
3. progesterone
4. estrogen

Human chorionic gonadotropin (hCG):
1. stimulates the anterior pituitary to secrete gonadotropins
2. directly maintains the endometrium
3. triggers continued production of progesterone by the corpus luteum
4. stimulates development of the mammary glands

Union of the vas deferens with the duct of the seminal vesicle that opens into the prostatic duct is:

The process of maturation of spermatids to sperms and the cells that facilitate this process are respectively:
1. spermiogenesis; sustentacular cells
2. spematocytogenesis; spermatogonia
3. spermiation; Sertoli cells
4. spermatogenesis; interstitial cells

In males, parasympathetic and sympathetic stimulation lead respectively to:
1. sterility; impoetnce
2. impotence; sterility
3. erection; ejaculation
4. ejaculation; erection

Capacitation occurs in
1. rete testis
2. epididymis
3. vas deferens
4. female reproductive tract

Which of the following depicts the correct pathway of transport of sperms?
