HYDROSALPINX LINK TO INFERTILITY
A hydrosalpinx blockage is typically on the far end of the fallopian tube, near the ovaries, but it is possible for blockage to exist at both ends.
In a healthy reproductive system, the fallopian tube serves as both the pathway for an ovulated egg to reach the uterus. After an egg is released from the ovary, finger-like projections from the fallopian tube draw the egg in.
Assuming sex has taken place close to ovulation, the egg will meet with sperm inside the tube. Fertilization of the egg will occur inside the tube—and not inside the uterus, which is a common misconception. The fertilized egg, or embryo, will make its way down the tube, into the uterus, and implant itself into the uterine wall.
If this pathway is blocked, as it is with a hydrosalpinx, infertility may result.
Normally, finger-like projections called fimbriae extend from the end of the fallopian tube close to the ovary. They help draw in the ovulated egg from the ovary into the fallopian tube. With a hydrosalpinx, the fimbriae are often damaged and stuck together.
Depending on the cause for the hydrosalpinx, additional adhesions around the fallopian tube and ovary may occur. This can also interfere with ovulation and fertility.
PREGNANCY CHANCES WITH ONE HYDROSALPINX BLOCKED TUBE
Technically speaking, it is possible to conceive with just one open tube, as may be the case if you have one hydrosalpinx tube and the other is healthy. However, the delicate environment of the uterus may be affected with a hydrosalpinx and this reduces pregnancy rates.
The irritation and adhesions associated with the hydrosalpinx seem to reduce the possibility of conception occurring via the healthy tube. It’s also possible that the fluid buildup inside the affected tube may leak into the uterus, impacting embryo implantation.
