Infertility tests for men The doctor will ask the man about his medical history, medications, and sexual habits and carry out a physical examination. The testicles will be checked for lumps or deformities, and the shape and structure of the penis will be examined for abnormalities. Semen analysis: A sample may be taken to test for sperm concentration, motility, color, quality, any infections, and whether any blood is present. Sperm counts can fluctuate, so that several samples may be necessary. Blood test: The lab will test for levels of testosterone and other hormones. Ultrasound: This may reveal issues such as ejaculatory duct obstruction or retrograde ejaculation. Chlamydia test: Chlamydia can affect fertility, but antibiotics can treat it.
