Infertility Problems

Infertility primarily refers to the biological inability of a person to contribute to the conception. Infertility may also refer to the state of a woman who is unable to carry a pregnancy to full term. There are many biological causes of infertility, some of which may be bypassed with medical intervention.

About 10 percent of reproductive-age couples in the United States will have difficulty getting pregnant. About 30 percent of cases are due to problems in the woman, 30 percent to problems in the man and the rest to unexplained causes or multiple factors involving both partners.

If you’ve had regular, unprotected sex for more than a year (or six months if you’re over 35) without conceiving, see your doctor. Nearly 90 percent of couples with infertility problems can be successfully treated.

Read on to learn about the common causes of infertility, treatments, and how many couples become pregnant with treatment. Keep in mind that success rates may vary, since one couple can have multiple problems.

Common causes of infertility in Women:

Endometriosis

Endometriosis is a condition that occurs when tissue found in the uterine lining (called endometrial tissue) grows outside your uterus, usually in the abdominal-pelvic cavity.

Possible symptoms: Some women have no symptoms, while others have painful menstrual periods or intercourse and general pelvic pain.

Possible solutions: Fertility drugs with artificial insemination, surgery to remove abnormal tissue or unblock tubes, assisted reproductive technologies (ART) or adoption.

Success rates: When fertility drugs is to increase egg production are combined with artificial insemination, the success rate is between 8 and 17 percent per cycle. Between 20 and 50 percent conceive after surgery (either naturally or with treatment) and between 20 and 30 percent conceive with ART treatments.

Ovulation Problems

An ovulation problem is any condition (usually hormonal) that prevents the release of a mature egg from your ovaries.

Possible symptoms: absent or infrequent periods and abnormally light or heavy bleeding.

Possible solutions: fertility drugs and in vitro fertilization.

Success rates: About 70 to 90 percent of couples ovulate with treatment and of those, 20 to 60 percent get pregnant.

Poor Egg Quality

If your eggs are damaged or have chromosomal abnormalities, they can’t sustain a pregnancy. The quality of your eggs declines significantly with age.

Possible symptoms: none

Possible solutions: In vitro fertilization (IVF) using donor eggs or embryos, or adoption

Success rates: Couples who undergo IVF with donor eggs have about a 30 to 50 percent chance of having a baby per IVF cycle.

Common causes of infertility in Men:

Blockages

A small percentage of men have a blockage in their ejaculatory duct that prevents sperm from getting into their ejaculate fluid. If your vas deferens or epididymis tubes are blocked or damaged, they can prevent your sperm from getting to your partner’s egg. Infection, injury, congenital defects, or a vasectomy could cause this blockage.

Possible symptoms: none

Possible solutions: Surgery to repair an obstruction or reverse the vasectomy

Success rates: Depending on the problem and the type of surgery used to treat it, about 50 to 90 percent of men have more sperm in their semen after surgery. About 20 to 65 percent of couples can conceive either through intercourse or with in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).

Varicocele

Varicocele (enlarged veins, similar to varicose veins, in the scrotum) raise the temperature in the testes which may affect sperm production.

Possible symptoms: None. (The problem can be detected through a physical exam.)

Possible solutions: Surgery to repair the varicocele

Success rates: Upto 43 percent of men impregnate their partner within a year of surgery and upto 69 percent do so within two years.

Irregular Sperm

zIf you have little to no sperm, poor sperm motility (its ability to move), or abnormally shaped sperm, your sperm may not be able to fertilize your partner’s eggs on its own.

Possible symptoms: none

Possible solutions: fertility drugs; artificial insemination with donor sperm or with your own if your count, shape, and motility are not too abnormal; or intracytoplasmic sperm injection (ICSI)

Success rates: When fertility drugs increase egg production and are combined with artificial insemination, the success rate is between 8 and 17 percent per cycle. The success rate is about 30 percent per cycle with ICSI.
