Why is it infertile to have sex during ovulation?

Many couples believe that they can get pregnant as long as they have sex during the ovulation period, but this is not true. Pregnancy requires all kinds of conditions to be supported for fertilization. Not only does it have to be during the ovulation period, but both parties must be in good health and the quality of the eggs and sperm must be good.

Causes of infertility during ovulation

1. Abnormal fallopian tube

Ovulation occurs, and some patients suffer from infertility due to blockage of the fallopian tubes. This is the main cause of female infertility. When the fallopian tubes become inflamed, mucosal secretions decrease, the lumen becomes adhered, and the peristalsis of the entire fallopian tube weakens, which not only leads to infertility, but also increases the chance of ectopic pregnancy. When suffering from pelvic endometriosis, the fallopian tubes may become adhered and twisted, leading to female infertility.

2. Uterine factors

Uterine abnormalities may also be a cause. The normal position of a woman's uterus is generally forward-tilted and forward-flexed, with the cervical opening facing backwards. After sexual intercourse and ejaculation, the cervical opening invades the semen pool, which is very beneficial for conception. If the uterus is retroverted or bent, the cervical opening will move forward and upward, which will make it difficult for sperm to enter the uterine cavity and cause infertility. If you suffer from endometritis, it will hinder the implantation of the fertilized egg.

3. Cervical lesions

The cervix is ​​the first barrier for sperm to pass through. If a disease occurs, sperm motility will decrease, making it difficult for a fertilized egg to form, resulting in infertility. If you suffer from chronic cervicitis or low estrogen levels, the cervical mucus may contain many white blood cells or become thick, which may affect female conception. Cervical polyps can block the passage of sperm.
