Infertility can be caused by blocked fallopian tubes and hydrosalpinx. There are also many cases of non-patent fallopian tubes, but pelvic adhesions may impair the ciliary motility function of the fallopian tubes, leading to abnormal transport of the fertilized egg back to the uterine cavity, resulting in infertility.
What adverse effects can hydrosalpinx have on fertility?
Detrimental to normal embryo development: Under pressure, fluid from the hydrosalpinx may reflux into the uterine cavity. On one hand, the fluid affects the process of the embryo merging with the endometrium, and on the other hand, it prevents the embryo from finding suitable “soil” for implantation.
Causing embryo developmental arrest: Hydrosalpinx is like a pool of “dirty water”, containing a large amount of bacteria and other harmful substances that severely affect embryo development.
Hindering embryo implantation: The primary cause of this fluid accumulation is often chronic inflammation, which may lead to fibroblast proliferation, thickening and narrowing of blood vessel walls, reducing blood flow to the endometrium and sub-endometrium, making it unfavorable for the embryo to “take root” in the uterus;
Affecting sperm motility: Hydrosalpinx may also reduce sperm motility and acrosome reaction capabilities within the female reproductive tract, affecting egg fertilization and causing infertility.
Before in vitro fertilization (IVF) transfer, it is generally advised that hydrosalpinx should be surgically ligated and removed first.
Generally, purulent hydrosalpinx can turn into serous, which means hydrosalpinx. When hydrosalpinx occurs, the fallopian tubes and uterine cavity can still be connected, and some fluid may partially drain into the pelvic cavity, leading to pelvic effusion, which requires vigilance during the preparation for pregnancy.
