Patient's question:
Where can uterine fibroids infertility be treated in Wuhan? How do uterine fibroids cause infertility?Doctor's answer:
HelloUterine fibroids are the most common solid benign tumors in the female reproductive system. Uterine fibroids are formed by the proliferation of smooth muscle tissue and are most common in the 30-40 age group. They can grow as a single or multiple lesions of varying sizes. The etiology of uterine fibroids is still unclear, but most believe it is related to excessive estrogen stimulation in the body. The incidence of infertility in patients with uterine fibroids is approximately 22-32%, with submucosal fibroids having the highest rate of infertility.
Uterine fibroids can be classified based on their location into subserosal fibroids, intramural uterine fibroids, submucosal fibroids, cervical fibroids, and ligamentous fibroids, among others. Generally, small or solitary subserosal and intramural fibroids do not affect fertility or pregnancy.
Infertility caused by uterine fibroids can occur in the following scenarios:
(1) Large fibroids can deform the uterine cavity, making it difficult for sperm to pass through, as well as for the fertilized egg to implant and for fetal development.
(2) Fibroids growing near the uterine angles can compress the opening of the fallopian tubes, causing blockage. Pressure may affect their patency, or the ovaries may be displaced, widening the distance between the ovaries and the fallopian tubes, thereby hindering the fimbriae's ability to pick up eggs.
(4) Fibroids growing in the cervix can compress the cervical canal, obstructing the passage or altering the orientation of the cervical os, making it farther from the seminal pool in the posterior fornix, which is unfavorable for sperm entering the cervical canal.
(5) Submucosal fibroids growing in the uterine cavity are like an intrauterine device placed in the cavity, hindering fertility. The ischemia, necrosis, and atrophy of the endometrium on the surface of the uterine cavity are also unfavorable for fertilized egg implantation.
(6) Uterine fibroids can increase the frequency, amplitude, and duration of uterine contractions beyond normal baseline, interfering with fertilized egg implantation or causing miscarriage after implantation. When fibroids are accompanied by endometrial hyperplasia, it indicates ovulatory dysfunction. Fibroids causing uterine bleeding and leading to infection can also block the fallopian tubes, all of which can result in infertility.
