A Correct answer
Explanation

Andrologists are medical specialists who diagnose and treat disorders of the male reproductive system. This includes conditions affecting male fertility, sexual dysfunction, hormonal imbalances, and structural abnormalities. The term 'andrology' is derived from 'andro' (male) and 'logy' (study of), making it the male counterpart to gynecology (female reproductive medicine).

Multiple choice

The process of preserving germ plasm in frozen state is called

  1. cryopreservation

  2. cold storage

  3. in situ preservation

  4. vernalisation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

 Cryopreservation or cryoconservation is a process where cells, whole tissues, or any other substances susceptible to damage caused by chemical reactivity or time are preserved by cooling to sub-zero temperatures.

Multiple choice

In sperms, lytic enzymes are present in

  1. middle piece

  2. tail

  3. acrosome

  4. nucleus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The acrosome is a specialised structure that is inside the tip of the sperm cell. It is derived from the Golgi complex during the maturation of the sperm. It is basically a storage vesicle that contains hydrolytic enzymes that digest proteins and complex sugars. The contents of the acrosome are secreted once the sperm makes contact with the egg. These enzymes will break down the zona pellucida, forming a thin path that allows the sperm to approach the egg and fuse with its cytoplasm.
