How much is the pelvic fluid during ovulation?

Generally speaking, pelvic effusion indicates pelvic inflammation, which is a relatively serious disease. However, women have a special period, that is, ovulation period, when some effusion is a normal physiological phenomenon. So, how much pelvic effusion is there during ovulation?

During a woman's menstrual period and the last few days after her menstrual period, some menstrual blood may flow along the fallopian tubes into the pelvic cavity, and a small amount of fluid may be seen on ultrasound. Or after ovulation, follicular fluid may flow into the pelvic cavity along with the ruptured follicles, usually in small quantities, and only a few may be seen on ultrasound. Both of these can disappear naturally, do not require treatment, and will not cause harm to the body.

There is very little fluid in the pelvic cavity, mainly to reduce the friction between the visceral peritoneum and the parietal peritoneum. The normal value of female pelvic effusion should be less than 10mm. Physiological pelvic effusion is less than 10mm, which can be produced during ovulation and early pregnancy. Physiological pelvic effusion of 10mm can generally be absorbed by itself within one or two months.

After knowing that pelvic fluid accumulation is normal before and after ovulation, if it exceeds this range or a larger accumulation of fluid is found during ovulation, it is pathological pelvic fluid accumulation. If the pelvic fluid accumulation exceeds 10mm, it is mostly pathological pelvic fluid accumulation. At this time, even if the pelvic fluid accumulation is more serious.

Most pelvic effusions are caused by exudation from chronic pelvic inflammation. If there are chronic infection lesions, it may be inflammation of the gynecological system such as pelvic inflammatory disease, adnexitis, endometriosis, ovary, and fallopian tube. It may also be caused by tuberculosis. There are also a few cases caused by ruptured ectopic pregnancy, corpus luteum rupture, and pelvic abscess. Therefore, physiological pelvic effusions need to be actively treated.
