What are the common phenomena of male infertility? Male infertility has brought a certain impact on people's lives, so what are the common phenomena of male infertility? Regarding this issue, let's invite our experts to explain the common phenomena of male infertility.

What are the common phenomena of male infertility? The following is an introduction to common phenomena of male infertility:

1. Azoospermia

Azospermia refers to the absence of sperm after centrifugation of ejaculated semen and microscopic examination. There are two major categories of azoospermia: the first is testicular spermatogenesis dysfunction, which prevents sperm production, also known as true azoospermia. The second type is testicular spermatogenesis function is normal, but the vas deferens duct is blocked, sperm cannot be discharged outside the body, also known as obstructive azoospermia. This is one of the common phenomena of male infertility.

2. Low semen volume

Generally, a normal male ejaculates approximately 2 to 6 ml per ejaculation, and the amount of ejaculation is related to the frequency of ejaculation. Less than 1 ml of semen at a time is called oligospermia.

3. Prolonged semen liquefaction time

Normal semen is in a liquefied state at the time of ejaculation, and immediately forms a jelly or clot. After 5 to 20 minutes in a 37 degree water bath, semen changes from a frozen state to a liquefied state, a phenomenon known as semen liquefaction. If this process is longer than 1 hour, it is called an extension of semen liquefaction time. This is also a common phenomenon of male infertility.
