Q. No.Male fertility primarily depends on sperm count. Sterility is likely if the count is below:
1. 100,000,000 / ml
2. 20,000,000 / ml
3. 100,000 / ml
4. 1,000 / ml
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
GnRH release by hypothalamus would be decreased due to:
1. decreased inhibin
2. increased testosterone
3. decreased FSH
4. decreased LH
The first haploid cell in sperm lineage is:
1. primary spermatocyte
2. secondary spermatocyte
3. spermatogonium
4. spermatid

The testes of a pre-pubertal boy will have:
1. spermatocytes
2. spermatozoa
3. spermatogonia
4. spermatid
Which of the following depicts the correct pathway of transport of sperms?
1. Rete testis →Efferent ductules → Epididymis → Vas deferens
2. Rete testis → Epididymis → Efferent ductules → Vas deferens
3. Rete testis → Vas deferens → Efferent ductules → Epididymis
4. Efferent ductules →Rete testis → Vas deferens →Epididymis
Identify the correct statement regarding the onset of puberty amongst the following:
1. LH is the first hormone to demonstrate an increased secretion
2. GnRH secretion decreases
3. spermatogenesis in males in stopped
4. secretion of sex steroids decreases
FSH:
1. Acts on Sertoli cells and stimulates secretion of some factors that help in spermiogenesis
2. Acts on Sertoli cells and inhibits secretion of some factors that help in spermiogenesis
3. Acts on Leydig cells and stimulates secretion of some factors that help in spermiogenesis
4. Acts on Leydig cells and inhibits secretion of some factors that help in spermiogenesis
