Delayed second menstruation after egg retrieval

The in vitro fertilization method is becoming more and more popular among the people. Because women have difficulty fertilizing due to their physical constitution, they have to conceive by combining the fertilized egg in vitro and then implanting it into the body. Before undergoing in vitro fertilization, women need to retrieve eggs, which is a very painful process, so some abnormalities will occur in the woman's body after the egg retrieval. So is it normal for the second menstrual period to be delayed after egg retrieval?

1. Reasons for delaying the second menstruation after egg retrieval

1. This starts before egg retrieval. In order to obtain a certain number of eggs for doctors to take out and fertilize in vitro, thereby increasing the chances of success of each IVF, most of the doctor's patients and friends have undergone superovulation treatment.

2. During superovulation, in order to obtain more eggs than the natural state (1), drugs are used to reduce the sensitivity of the pituitary gland, blocking the hypothalamus-pituitary-gonadal axis, causing the pituitary gland to lose control of the ovaries. Thus, exogenous hormones replace endogenous hormones, act on the ovaries, and stimulate the growth and development of multiple follicles.

3. After the egg retrieval operation, the doctor will provide luteal support to the transplanted patient and use drugs to promote endometrial decidualization to maintain pregnancy. For those who do not undergo transplantation, stopping the medication will remove the effects of exogenous hormones. Because the hypothalamus-pituitary-gonadal axis is blocked, endogenous hormones are also insufficient, hormone levels drop, and menstruation occurs. This is the first menstruation. Menstruation is not caused by ovulation and endogenous hormones, but by the withdrawal of exogenous hormones and withdrawal bleeding.

4. Menstruation has come, but for most friends, the hypothalamus-pituitary-gonadal axis is still resting and ovulation has not yet resumed. Therefore, the next menstruation may have to wait until endogenous hormones regain control of the ovaries and ovulation resumes. This is why the "second period" is late.

2. Precautions after egg retrieval

1. After egg retrieval, women must take medication as required by the doctor and must not reduce or stop taking medication without authorization.

2. Avoid strenuous exercise, do not make large movements, avoid riding electric bikes, motorcycles and other strenuous activities. Prevent ovarian torsion. After the egg retrieval operation, there will be a small amount of exudate around the ovaries, which may cause mild abdominal pain, back pain and other discomforts, so please rest in bed for 1-2 days.

3. After egg retrieval, both husband and wife should abstain from sexual intercourse for half a month.

4. Bathing and swimming are prohibited after egg retrieval, but showering is allowed.
