- LH is a Luteinizing hormone produced by the gonadotropic cells in the anterior pituitary gland.
- It plays an important role in puberty, menstruation, and fertility.
- It triggers ovulation and development of the corpus luteum.
- In male, LH triggers the secretion of androgen called as testosterone from the Leydig cells.
- FSH is follicle-stimulating hormone produced by gonadotropic cells in the anterior pituitary gland.
- It helps in regulation of development, growth, pubertal maturation and reproductive processes of the body.
- It stimulates the Sertoli cells of the testicles and helps in spermatogenesis, production of sperm.
- During the follicular phase, the LH and FSH increase gradually.
- They stimulate follicular development and estrogen secretion by follicular cells.
Thus, the correct answer is 'LH and FSH decrease gradually during the follicular phase.'

Incorrect Statement Explanation:
LH and FSH decrease gradually during the follicular phase
During the follicular phase of the menstrual cycle, both LH (Luteinizing Hormone) and FSH (Follicle-Stimulating Hormone) actually increase rather than decrease. These hormones play crucial roles in the maturation of ovarian follicles and the subsequent ovulation process.
Correct Statements:
LH and FSH triggers ovulation in ovary
LH and FSH are responsible for triggering ovulation in the ovary. LH surge causes the mature ovarian follicle to release the egg during ovulation, while FSH helps in the development and maturation of the follicles.
LH triggers secretion of androgens from the Leydig cells
LH does trigger the secretion of androgens, such as testosterone, from the Leydig cells in the testes. This hormone is essential for the development and maintenance of male reproductive tissues.
FSH stimulates the Sertoli cells which help in spermiogenesis
FSH stimulates the Sertoli cells in the testes, which are crucial for supporting and nourishing developing sperm cells. These cells play a key role in spermatogenesis and spermiogenesis processes.
In summary, the incorrect statement is that LH and FSH decrease gradually during the follicular phase, when in fact they increase to support the maturation of follicles and ovulation.
