How long does it take to get menstruation after IVF egg retrieval?

In vitro ovulation retrieval refers to the use of medical artificial methods to remove eggs from the female body to cultivate a fetus. During the period of in vitro ovulation retrieval, the health and physical condition of the body are very critical. After in vitro ovulation retrieval, women's menstruation is prone to be early. This is due to stimulation of the body or stimulation of ovulation-inducing drugs. Menstruation will occur 14-13 days after in vitro ovulation retrieval.

After the IVF egg retrieval, the expectant mother's menstruation will generally be delayed. Normally, menstruation occurs 14 days after egg retrieval. It is normal for women to have early menstruation after egg retrieval but without transplantation and without using progesterone for ten to fourteen days. In this case, women's menstruation will generally come early. This is mainly because ovulation induction affects the function of the corpus luteum and ovaries, and has nothing to do with future test tube baby transplantation.

During the IVF period in Daye Town, the follicles will basically not grow again after the night injection of IVF. The night injection is for human chorionic gonadotropin, and it should be given at the time prescribed by the doctor, no more than five minutes before and after, and the injection site is the buttocks muscle.

The woman will have her blood drawn on the morning of the second day after the night injection, and both husband and wife need to take a bath the night before egg collection. Expectant mothers do not need to be overly nervous about the night injection for IVF, as this will help their bodies recover after the IVF egg retrieval.

During the IVF treatment process, some people may encounter situations where there are fewer eggs or the quality of the eggs is poor.

One of the reasons for low egg retrieval

Decreased ovarian function

Generally speaking, the older a woman is, the lower her ovarian function will be, and thus fewer eggs will be retrieved through ovulation induction. At the same time, there are also some young women suffering from infertility. Their ovarian function also declines, and it is not easy to stimulate the release of 1-2 eggs. The initial manifestation of decreased ovarian function is a shortened menstrual cycle, followed by irregular menstruation.

Ovarian function affects the success rate of IVF. The ovarian condition of older women is more likely to change in a short period of time. Therefore, it is better to do IVF as early as possible and take action once you have made up your mind. Don't wait until your ovarian function is almost exhausted before trying assisted pregnancy. It will be too late to regret then.

The second reason for low egg retrieval

Egg retrieval time

Generally, in the IVF or IVF course, eggs will be retrieved between 35-36 hours after the "night injection".

The "night injection" is the last injection after ovulation induction and before egg retrieval. Because this injection is usually arranged by the doctor to be given at night, we commonly call it the "night injection." The egg is wrapped by cumulus cells and adhered to the wall of the follicle. The function of the "night needle" is to promote the maturation of the egg, loosen the cumulus cells, make the egg easier to fall off from the follicle wall, and facilitate egg retrieval.

It is generally believed that if the interval between egg retrieval and the "night injection" is less than 35 hours, the follicles may be immature, that is, the cumulus cells have not yet loosened and the eggs are not easy to fall off, then the eggs cannot be retrieved; and if the interval time is more than 36 hours, it is possible that some follicles have spontaneously ovulated and cannot be retrieved. Both situations will result in low egg retrieval rate or even no eggs can be retrieved.

However, each person's situation is unique. There will always be a small number of people whose eggs mature at a different time than others. Some may be ovulated in less than 35 hours, while others may not mature even after 36 hours. Some sisters may have their eggs retrieved 35 hours after the "night injection", when most of the follicles have already been discharged. Some sisters may wait for 37 hours after the "night injection" before taking out the eggs. These special individual differences are not something we can predict. What we can do is: First, get the night injection on time, preferably not too early or too late.
