Question

Quizplus · Accepted Answer

The sperm count in a normal ejaculate is approximately 100 to 400 million. Infertility may occur when insufficient numbers of motile, healthy sperm are present. A "fertile sample" on seminal fluid analysis is associated with a count greater than 20 million/mL, greater than 50% motility, normal morphology, and a volume of 1.5 to 6 mL.
