The spermatids are transformed into spermatozoa by the process called:

1. Spermiation

2. Spermatocytogenesis

3. Spermiogenesis

4. Spermatolysis

Which of the following hormones acts on the Sertoli cells to stimulate secretion of some factors which help in the process of spermiogenesis?

1. FSH

2. LH

3. Testosterone

4. GnRH

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

Which one of the following statements about human sperm is correct?

1. Acrosome has a conical pointed structure used for piercing and penetrating the

egg, resulting in fertilization

2. The sperm lysins in the acrosome dissolve the egg envelope facilitating fertilization

3. Acrosome serves as a sensory structure leading the sperm towards the ovum

4. Acrosome serves no particular function

The correct sequence of spermatogenetic stages leading to the formation of sperms in a

mature human testis is

1. spermatocyte - spermatogonia - spermatid - sperms

2. spermatogonia - spermatocyte - spermatid -sperms

3. spermatid-spermatocyte-spermatogonia -sperms

4. spermatogonia-spermatid-spermatocyte -sperms

In humans, at the end of the first meiotic division, the male germ cells differentiate into

the 

1. primary spermatocytes

2. secondary spermatocytes

3. spermatids

4. spermatogonia

How many sperms are formed from a secondary spermatocyte?

(1) 4

(2) 8

(3) 2

(4) 1

Assertion   :       Spermiation is the transformation of spermatid into sperm.

Reason      :       During spermiation, sperms get nutrition from sertioli cells.

Which of the following cell will undergo meiosis?

Which of the following does not has 46 chromosomes?
