Infertility Tests for Men
For men, an evaluation of infertility includes a medical history and physical examination to detect any anatomic abnormalities. In some cases, examination using trans-rectal ultrasound (TRUS) can be used to identify specific abnormalities, such as obstructions blocking the sperm from being released during ejaculation. Absence of sperm (azoospermia) can also be due to missing vas deferens or seminal vesicles.
Semen analysis—this is the primary test for infertility in men. Collection and prompt evaluation of a sample of semen can help determine whether there are any defects in the number, shape, and movement (motility) of sperm.
Blood tests can be used to evaluate hormone levels such as:
- Free and total testosterone
- Luteinizing hormone (LH)
- Follicle-stimulating hormone (FSH)
- Prolactin (PRL)
- Sex hormone binding globulin (SHBG)
In some instances, a biopsy of testicular tissue can identify infertility problems such as sperm production, abnormal growths, tumors, or underdeveloped reproductive organs.
