Approximately 25% of infertile couples will have unexplained infertility
Infertility is defined as the lack of successful conception while having unprotected intercourse for twelve months in couples where the woman is 35 or younger, or six months in cases where the woman is older than 35 . Couples 35 or younger who have successfully conceived in the past with each other have a 50% chance of conception within 3 months of attempting pregnancy; a 75% chance by 6 months, and an 88% chance by 12 months. Those couples without conception after 12 months of trying have less than a 3% chance of conception each month. They should see a fertility specialist for an evaluation.
After a full evaluation, sometimes no explanation is found.
Our physicians will perform a thorough evaluation to identify the reason(s) that natural conception has not occurred. After taking a complete medical history and performing a comprehensive physical examination, they will thoroughly evaluate your anatomy to make sure that your uterus is normal, that your fallopian tubes are open, and that your ovaries appear normal. They will also check to ensure that your partner has normal sperm production and motility. Blood work can help determine if your ovaries have a good number of eggs present. Some patients may benefit from surgery to more closely evaluate the inside of the uterus and/or the ovaries and fallopian tubes, in order to treat endometriosis, uterine fibroids, pelvic adhesions (scar tissue) and other fertility issues that are not found with less invasive testing.
Most couples with unexplained infertility will be successful with treatment.
Most of the time, we will find one or more causes that explain difficulty with conception. When a complete evaluation finds no cause, we call this unexplained or idiopathic infertility. Unexplained infertility is very frustrating, as couples experiencing infertility hope to find a simple explanation and treatment options. Approximately 25% of infertile couples will have no explanation for their infertility, but it is important to know that even without a definitive explanation, there are well-defined treatments for unexplained infertility. The vast majority of patients will ultimately conceive successfully as a result of these treatments.
