Infertility Testing for Men
Because the cause of infertility can result from a female factor, a male factor, or both, it's important that both partners undergo some basic testing. Thirty percent of infertility is due to a male problem, such as structural abnormalities, sperm production disorders, ejaculatory disturbances, and immunologic issues. The male evaluation could involve:
- A thorough physical exam, including an examination of the external genitals and rectal area to identify any structural abnormalities.
- Blood tests to rule out certain diseases and STDs, and to determine the level of testosterone and other hormones in the blood.
- Urine tests to rule out problems such as diabetes and kidney infection.
- A semen analysis to check for sperm count, motility, and morphology, as well as other factors.
- A small biopsy of the testicles, in case a semen analysis shows that no sperm is present.
If the doctor suspects that a man has varicocele (a varicose vein in the testicle), he may perform a Doppler ultrasound or venography (an X-ray of the testicular veins) to evaluate blood flow and locate the problem. Varicoceles are a common structural problem in men and account for at least 40 percent of all male infertility
