Incorrect statement: LH and FSH decrease gradually during the follicular phase
Explanation:
- LH (luteinizing hormone) and FSH (follicle-stimulating hormone) are two important hormones involved in the regulation of the reproductive system in both males and females.
- In females, LH and FSH are responsible for the development and maturation of ovarian follicles, which ultimately leads to ovulation and the production of estrogen and progesterone.
- The menstrual cycle in females is divided into two main phases: follicular phase and luteal phase. The follicular phase begins on the first day of menstruation and ends with ovulation, while the luteal phase begins after ovulation and ends with the next menstruation.
- During the follicular phase, LH and FSH levels increase gradually, which stimulates the growth and development of ovarian follicles. This phase typically lasts for around 14 days in a 28-day cycle.
- LH and FSH levels peak just before ovulation, which triggers the release of a mature egg from the ovary. This is known as the LH surge.
- After ovulation, LH and FSH levels decrease and remain low during the luteal phase.
- Therefore, the statement that LH and FSH decrease gradually during the follicular phase is incorrect. They actually increase gradually during this phase and peak just before ovulation.

Select the incorrect statementa)LH and FSH triggers ovulation in ovary...
Explanation:
The incorrect statement is option B - LH and FSH decrease gradually during the follicular phase.
During the menstrual cycle, the levels of LH and FSH (luteinizing hormone and follicle-stimulating hormone) fluctuate in order to regulate the growth and development of follicles in the ovary and the production of estrogen and progesterone.
The menstrual cycle can be divided into two phases:
1. Follicular phase - this is the first half of the cycle, starting from the first day of menstruation and ending with ovulation. During this phase, FSH stimulates the growth and development of follicles in the ovary, which produce estrogen. As estrogen levels rise, it inhibits the release of LH and FSH, preventing the development of additional follicles.
2. Luteal phase - this is the second half of the cycle, starting after ovulation and ending with the start of the next menstrual period. After ovulation, the ruptured follicle (now called the corpus luteum) produces progesterone, which prepares the uterine lining for implantation. If fertilization does not occur, the corpus luteum degenerates and progesterone levels decrease, leading to the shedding of the uterine lining and the start of the next menstrual period.
Therefore, the correct statements are:
a) LH and FSH triggers ovulation in ovary
b) LH triggers secretion of androgens from the Leydig cells
c) FSH stimulates the Sertoli cells which help in spermiogenesis
And the incorrect statement is:
d) LH and FSH decrease gradually during the follicular phase
