In Lactational amenorrhoea, ovulation does not occu during the period of intense lactation because of

Options

A. High level of FSH & LH
B. Surge of Estrogen
C. Stimulation of GnRH
D. High level of prolactin

Answer

**Step-by-Step Solution:**

1. **Understanding Lactational Amenorrhea**: Lactational amenorrhea is a natural form of contraception that occurs in women during the postpartum period, particularly when they are breastfeeding intensely. This phase typically lasts for about 6 to 9 months after childbirth.

2. **Hormonal Changes Post Childbirth**: After giving birth, a woman's body undergoes hormonal changes. One of the key hormones involved during this period is prolactin, which is responsible for milk production.

3. **Role of Prolactin**: The levels of prolactin rise significantly during intense lactation. High levels of prolactin inhibit the secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus.

4. **Impact on Menstrual Cycle**: The inhibition of GnRH leads to a decrease in the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. FSH and LH are crucial for the menstrual cycle and for triggering ovulation.

5. **Conclusion**: Therefore, due to the high levels of prolactin during intense lactation, ovulation does not occur, resulting in the absence of menstruation and a reduced chance of pregnancy.

**Final Answer**: In Lactational Amenorrhea, ovulation does not occur during the period of intense lactation because of high levels of prolactin.
