Pregnancy happens in about 80-85% of couples within 12 months of trying to conceive, and in about 15-20% of couples, it takes longer than one year in order to get pregnant. Couples that are unable to get pregnant within 12 months of trying are generally considered to be infertile. Studies show an equal distribution of infertility causes among women and men. Infertility is caused by female factors alone in about 1/3 of all infertility cases, by male factors alone in another 1/3, and combined in 1/3 of all cases. In about 10-15% of cases no specific cause can be found (unexplained infertility).
Infertility symptoms in women
The main sign and symptom of infertility in women (and men) is not getting pregnant after intentionally trying for a certain amount of time by having regular intercourse on a regular basis. Most women do not have any other specific symptoms, but that can also depend on what is causing infertility.
Changes in the menstrual cycle and ovulation, such as not having regular menstrual bleeding or ovulation, may be the main symptom of a condition related to infertility.
The main infertility symptoms include:
- An ovulation disorder such as those associated with polycystic ovary syndrome (PCOS) is among the most common female infertility factor.
- A woman's age is an important factor in female infertility. The ability for ovaries to produce eggs or to produce eggs insufficient quality declines with age, starting after 30.
- Other causes of female infertility that are usually not associated with any specific symptoms include blocked fallopian tubes, which can occur when a woman has had pelvic inflammatory disease or endometriosis.
