- Ovaries. The best sign of regular ovulation is regular menstruation. If your periods are coming regularly--21 to 35 days apart--you are most likely ovulating. Longer or shorter periods could signify thyroid or pituitary dysfunction, which can be diagnosed through blood testing. Gynos can also evaluate the general state of your eggs, or "ovarian reserve," through specialized blood testing on day three of your period.
- Fallopian tubes. Scarring of the tubes sometimes occurs with pelvic inflammatory disease, endometriosis, or pelvic surgery. Your doc can order a special X-ray of your tubes called a hysterosalpingogram (HSG) if she suspects tubal blockage. If a blockage is found, there are multiple procedures that can be performed to clear the path.
- Uterus. Uterine anomalies like a septum, polyp or fibroids can impede a pregnancy's implantation. Often these anomalies don't cause any trouble, but if you have a history of super-heavy periods or several miscarriages, your gyno may order an HSG to check out the inner contours of your uterus. If something there is making mischief, it can be surgically removed.
