Intramural Fibroids and Infertility
Normally, intramural fibroids have no effect on fertility and pregnancy. However, in about 3% of women, these uterine fibroids are linked with infertility. Women who have multiple intramural fibroids or very large fibroids may find conceiving troublesome.
Intramural fibroids can prevent sperm from entering the uterine cavity, particularly when the fibroids are located at the cervix. These fibroids can also enlarge the uterine cavity, thereby increasing the distance that sperm need to travel to reach the fallopian tubes. Additionally, intramural fibroids may affect the uterus’ ability to contract, which has a direct impact upon sperm migration and ovum transport.
Implantation of the embryo can also be inhibited by intramural fibroids as they distort the uterine cavity, impairing the blood supply to the endometrium and disturbing the endometrium structure. Even if implantation has occurred successfully, intramural fibroids may interfere with the development of the foetus.
Uterine fibroids usually enlarge as the pregnancy proceeds. Due to this, there is a tussle for space between the growing baby and the intramural fibroids. This struggle may either induce developmental defects in the unborn child or may cause a miscarriage.
Now that doesn't sound entirely positive but it does say only %3 of women have their fertility affected.
