Sperm Penetration Tests

Hamster Zona-Free Ovum Test

Why It Is Done

Sperm penetration tests may be done:

• When other tests have not found a cause for infertility.
• To see how the sperm function when a semen analysis test has shown some problems, such as slow movement or the sperm look abnormal.
• To check when another test, the postcoital test, has found sperm dead or not moving in the cervical mucus.
• To test sperm before doing in vitro fertilization.
