Does sexual intercourse affect the implantation of the fertilized egg?

Pregnancy for women is a very complicated process. First, the egg must successfully combine with the sperm, then be transported to the uterus through the fallopian tube, and successfully implant in the uterus. Any problem in any step during this period may lead to pregnancy failure. When the fertilized egg implants in the uterus, the female body will have some reactions. So if you have sex at this time, will it affect the implantation of the fertilized egg?

Does sexual intercourse affect the implantation of the fertilized egg?

1. Factors that affect fertilized egg implantation that women who are preparing for pregnancy are concerned about

1. Will sexual intercourse affect the implantation of the fertilized egg?

I had sex with my husband six days after ovulation. I wonder if it will affect the implantation of the fertilized egg?

Expert: Sexual intercourse will not affect the implantation of the fertilized egg. Normal exercise and activities, including sexual intercourse, will not affect the implantation of the fertilized egg. Fertilization occurs within 12 hours after ovulation, and the entire fertilization process takes about 24 hours. . Sperm is very active and is generally capable of fertilizing within 72 hours, while eggs generally will not be fertilized after 24 hours and are most capable of fertilizing within 12 hours. Normal intercourse generally does not have much impact on pregnancy.

2. Will having sex after ovulation affect the implantation of the fertilized egg?

@梦涵: The egg has been fertilized on the day of ovulation. Will having sex with my husband after the ovulation period affect the implantation of the fertilized egg?

Expert: Having sex on the day of ovulation will not result in fertilization immediately. And the entire fertilization process takes about 24 hours. On the fourth day after fertilization, the blastocyst enters the uterine cavity and takes about 6-7 days to implant. Therefore, having sex after ovulation will not affect the implantation of the fertilized egg. However, after confirming pregnancy, try to avoid sexual intercourse within 3 months of early pregnancy to prevent miscarriage.

2. Factors that really affect the implantation of fertilized eggs

1. The fertilized egg itself is defective

Most of the time, it is always the healthiest sperm that combines with the egg, but in some special cases, some abnormal sperm will combine with the egg first. Sometimes, after the egg combines with one sperm, a second sperm also combines with the same egg, and the fertilized egg formed in this way has congenital defects. Therefore, before preparing for pregnancy, both husband and wife should check whether their chromosomes are abnormal so that a healthy fertilized egg can implant successfully.

2. Poor ovarian corpus luteum function, insufficient progesterone secretion, and abnormal endometrium affect the implantation of the fertilized egg.

Some women have been married for many years and have normal sex lives, but cannot get pregnant. It is very likely because their ovarian corpus luteum function is not healthy, progesterone secretion is insufficient, and endometrium is abnormal, which affects the implantation of the fertilized egg. Therefore, women who are planning to have a baby should undergo six hormone tests. The six-item hormone test is the most commonly used method for testing the endocrine function of men and women. By measuring the levels of sex hormones, it can timely understand diseases related to endocrine disorders. The results of the six sex hormone tests can, to a certain extent, reflect whether a woman's endocrine system is disordered and whether her ovarian ovulation is normal.

3. Uterine factors

These factors in the uterus affect the successful implantation of the fertilized egg. Therefore, if women who are planning to have a baby want to conceive successfully, they can undergo relevant treatment through hysteroscopy. Hysteroscopy can directly examine intrauterine lesions and quickly make an accurate diagnosis of most intrauterine diseases. Hysteroscopy is used to examine the cervical canal, uterine cavity and bilateral fallopian tube openings to identify factors that interfere with implantation of the fertilized egg. Hysteroscopy can also be used to perform related uterine surgeries to reduce physical damage and psychological trauma to women preparing for pregnancy.

4. Immune factors

For women, men's sperm and seminal plasma are obviously foreign bodies. But under normal circumstances, women do not produce anti-sperm antibodies. Only under certain circumstances, such as inflammation and damage to the female reproductive tract, will antibodies be produced in female serum and cervical mucus. At this time, the macrophages in the female reproductive tract, especially the uterus, will cause an immune response and perform "self-defense", which can make the sperm that has penetrated the cervix inactive, agglutinate or die.
