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:
1. | ampulla of vas | 2. | ejaculatory duct |
3. | urethra | 4. | efferent ductules |
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?
1. Rete testis →Efferent ductules → Epididymis → Vas deferens

Several hormones like hCG, hPL, oestrogen, and progesterone are produced by:
1. | ovary | 2. | placenta |
3. | fallopian tube | 4. | pituitary |
Identify the correct statement on ‘inhibin'
1. Is produced by granulosa cells in ovary and inhibits the secretion of FSH
2. Is produced by granulosa cells in ovary and inhibits the secretion of LH
3. Is produced by nurse cells in testes and inhibits the secretion of LH
4. Inhibits the secretion of LH, FSH and prolactin
Select the incorrect statement
1. LH and FSH trigger ovulation in ovary
2. LH and FSH decrease gradually during the follicular phase
3. LH triggers secretion of androgens from the Leydig cells
4. FSH stimulates the Sertoli cells which help in spermiogenesis
