If the fallopian tubes are clear and you have not gotten pregnant after several ovulation boosts, you may have abnormal uterine development, submucosal fibroids or endometrial polyps, endometriosis, male semen abnormalities or sexual dysfunction, or some unexplained infertility. If a woman’s fallopian tubes are clear and she is still not pregnant after several ovulation promotions, it is recommended that both husband and wife go to the hospital for a checkup because there are many factors that can lead to non-pregnancy, including the following: 1. Abnormal uterine development. If a woman has a longitudinal uterus, unicornuate uterus or double uterus, etc., it may affect her pregnancy. 2. If a woman has submucosal fibroids, or endometrial polyps, it may affect the fertilization of the egg, leading to early miscarriage and affecting the woman’s pregnancy. 3. Endometriosis. Endometriosis will not only lead to progressively worsening dysmenorrhea, but also 40% of patients may be infertile. 4. Male semen abnormality or sexual dysfunction. If there are congenital or acquired causes of semen abnormality, such as weak spermatozoa, azoospermia, malformed spermatozoa, etc., it will affect pregnancy. If a man has sexual dysfunction, such as inability to have an erection, non-ejaculation or retrograde ejaculation, it can also affect pregnancy. 5. Unexplained infertility. There is a type of unexplained infertility, which is a state of low fertility and low fertility, for example, there are immune factors, underlying oocyte abnormalities, embryo developmental blockage, and embryo implantation failure.
