Solution


Q.

Select the incorrect statement.                            [2016]
1 LH and FSH decrease gradually during the follicular phase.  
2 LH triggers secretion of androgens from the Leydig cells.  
3 FSH stimulates the Sertoli cells which help in spermiogenesis.  
4 LH triggers ovulation in ovary.  

Ans.

(1)

During follicular phase, FSH secretion increases. Follicular phase (proliferative phase) usually includes cycle days 6-13 or 14 in a 28 days cycle. The follicle stimulating hormone (FSH) secreted by the anterior lobe of the pituitary gland stimulates the ovarian follicle to secrete estrogen.
