Progesterone contraceptives lead to a suppression of luteinizing hormone (LH) secretion, by producing a negative feedback on the synthesis and release of the gonadotropin-releasing hormone (GnRH) from the hypothalamus. This leads to the absence of the FSH and LH surge, which is essential to mature the developing dominant follicle, and trigger the event of ovulation, thereby preventing ovulation. thus,op C.

Progesterone, the component of the oral contraceptive pills, prevents ...
Explanation:
Progesterone, the component of oral contraceptive pills, prevents pregnancy by blocking ovulation. Let's understand how it works in detail:
Ovulation:
Ovulation is the process in which a mature egg is released from the ovary and is available for fertilization. This is a crucial step in the reproductive cycle and occurs every month in women of reproductive age.
Progesterone:
Progesterone is a hormone naturally produced by the ovaries during the menstrual cycle. It helps prepare the uterus for pregnancy and maintains the pregnancy if fertilization occurs. In oral contraceptive pills, synthetic progesterone (progestin) is used to mimic the effects of natural progesterone.
Preventing Ovulation:
Oral contraceptive pills containing progesterone work by suppressing the release of luteinizing hormone (LH) from the pituitary gland. LH is responsible for triggering ovulation. When the level of progesterone in the body is increased through oral contraceptive pills, it suppresses the production of LH, preventing the release of the egg from the ovary. Without ovulation, there is no egg available for fertilization, thereby preventing pregnancy.
Additional Mechanisms:
In addition to preventing ovulation, progesterone also has other mechanisms that contribute to its contraceptive effects:
1. Thickening of Cervical Mucus: Progesterone causes the cervical mucus to thicken, making it difficult for sperm to penetrate and reach the egg.
2. Alteration of Uterine Lining: Progesterone alters the lining of the uterus, making it unfavorable for implantation of a fertilized egg. If fertilization does occur, the fertilized egg may not be able to implant and grow in the uterus.
Conclusion:
In conclusion, progesterone, the component of oral contraceptive pills, primarily prevents pregnancy by blocking ovulation. It suppresses the release of luteinizing hormone (LH), which is essential for triggering ovulation. Additionally, progesterone thickens the cervical mucus and alters the uterine lining, further preventing fertilization and implantation.
