What is uterine fibroids lead to infertility?

Hysteromyoma of female genital mutilation is the most common benign tumor of the entity. Uterine fibroids by the formation of smooth muscle hyperplasia, a good 30 to 40 years of age, may be single or multiple growth, sizes. Uterine Fibroids cause is not clear, but the majority believe in too much estrogen stimulate. Uterine fibroid incidence of infertility in patients with about 22 to 32 per cent, with submucosal fibroids highest incidence of infertility. Hysteromyoma in accordance with its location can be divided into subserosal fibroids, muscle intramural uterine fibroids, submucosal uterine fibroids, cervical fibroids, such as leiomyoma ligament. Generally small or single muscle of the subserosal intramural uterine fibroids and does not affect pregnancy and pregnancy. Uterine fibroids can lead to infertility following situations: (1) large uterine fibroids can intrauterine deformation, to the detriment of sperm through, as well as implantation embryos and fetal development. (2) growth in the uterus myoma angle near the fallopian tube openings can be oppressed, and cause obstruction. (3) Run ligament in the growth of the fibroids can benefit from the surface of the elongated distortion tubal lumen extrusion, affect its patent, or to change in ovarian, ovary and fallopian tube distance widened, prejudice tubal umbrella The egg-packing function. (4) growth in the cervix of the uterus myoma of the cervix can be oppressive. Obstruct or change the channel towards the mouth of the cervix, away from the pool after Konglongbu semen, to the detriment of sperm into the cervix dilated. (5) growth in the uterine cavity of submucosal uterine fibroids, like intrauterine placed a spherical IUD, impede fertility. Uterine endometrial surface ischemia, necrosis, atrophy, is not conducive to implantation embryos. (6) uterine fibroids can uterine contraction frequency, magnitude and duration of higher than normal baseline, or interfere with the implantation implantation embryos after abortion. When uterine fibroids with the proliferation of periosteal, said ovarian not ovulation, fibroids cause bleeding, infection incurred, in the fallopian tube obstruction, can cause infertility.
