A semen analysis is done with the male partner to assess the count and morphology of the sperm in the sample he provides. Results from this test could diagnose a previously unknown male factor infertility which would play a critical role in determining the most effective method of treatment.
Male infertility is the cause for roughly one-third of couples who have difficulty getting pregnant. Our andrology lab will look for these factors when analyzing sperm:
Low Sperm Count. In order for conception to take place, sperm need to be present – and the more sperm the better since the egg is a moving target that only lives for about 24-hours after ovulation. Normal sperm count ranges from 15-million to 200+ million sperm per milliliter of semen. A man is diagnosed with low sperm count (oligospermia) if his semen analysis contains less than 15-million sperm per milliliter or less than 39-million sperm per total amount of ejaculate. If there are 0 sperm present in the semen, he is diagnosed with azoospermia.
Abnormal Sperm Shape. Sperm need to be shaped correctly in order to penetrate the egg’s shell, or outer membrane. Sperm shape is also referred to as sperm morphology. If the sperm are poorly shaped, fertilization is difficult.
Poor Sperm Movement. In order to be effective, sperm need to be fast, strong swimmers. Sometimes, sperm are sluggish, indirect or wobbly movers that have a hard time fertilizing the egg. This is called poor sperm motility, and is another common cause of male infertility.
