What are the three major phases of menstrual cycle in primates?Mention the key event in each phase.
- Assertion: The middle piece of the sperm is called its power house.
Reason: Numerous mitochondria in the middle piece produce energy for the movement of tail.- Assertion: A decrease in temperature has no effect on spermatogenesis.
Reason: Spermatogonia cannot survive the high body temperature.- Assertion: The region inside the seminiferous tubules contain Leydig cell.
Reason: Leydig cells synthesise and secrete androgen.why is placenta called a temporary endocrine gland?
