Worldwide reports suggest that infertility affects 15%–20% of couples of reproductive age and that about 40% of these cases are attributable to the male partner.

When you and your partner can’t get pregnant, the first step is scheduling an infertility evaluation with Fangyin Meng, MD, PhD. Dr. Meng is a specialized infertility doctor, she will work together with you and your partner to determine the best way to help you have a baby.



Since sperm number and function are critical in reproduction, let’s begin by exploring sperm development. The entire process of spermatogenesis is variously estimated as taking 74 days[8][9] and approximately 120 days.


Preparing for a semen analysis

You should not have sex or masturbate at least 2-3 days before your scheduled test. However, you should not go longer than five days without sex. These steps ensure your sperm count and quality are optimal, which gives us the most accurate results. And we also recommend drinking enough water before collecting the sample.

Obtaining your semen sample

In Dr. Meng’s practice, We have room for you to collect samples or you can collect at home and send to us within 1 hour.



Average ejaculate is at least 2cc.

Sperm count

The number of sperm ejaculated has a significant impact on your ability to fertilize your partner’s egg. A low sperm count is one of the top causes of male infertility.

Sperm motility

Motility refers to how well and what percentage of sperms are moving. Healthy sperm need to have fast, forward movement to reach and fertilize their partner’s egg.  We determine the number of sperm in your semen sample that has good versus bad motility.

White blood cells


It is normal to have white blood cells in semen, but if there are too many, it could be bacterial or viral infection.

If your semen analysis reveals any abnormalities, we talk with you about what they mean and explain your next step. In some cases, we may need to do other diagnostic tests if it is abnormal.

If you have any questions about getting a semen analysis or you need to schedule an infertility evaluation, call Fangyin Meng, MD, PhD, or book an appointment online today.
