Answer 2

Answer:

Function of testes –

a) Spermatogenesis – Testes produce male gametes sperm.

b) Secretion of hormone – Testes secrete hormone testosterone – the male sex hormone which helps in regulation of spermatogenesis and also maintains structure and function of secondary sex characters like facial, axial and public hair, voice moustache, etc.

The testes are situated outside the abdominal cavity within a pouch called scrotum. The scrotum helps in maintaining the low temperature of the testes (2-2.5°C lower than the normal internal body temperature) necessary for spermatogenesis.
