Patient's question:
My husband has been diagnosed with asthenozoospermia for a long time, and we haven't had any children. We feel very distressed. Could you please ask the doctor, what are the specific causes of asthenozoospermia?Doctor's answer:
Azoospermia refers to a condition where the percentage of progressively motile sperm (grades a and b) in semen parameters is less than 50% or the percentage of grade a motile sperm is less than 25%. Azoospermia is also known as low sperm motility, and it is one of the causes of male infertility. After normal ejaculation, sperm are restricted in movement before the semen evaporates. Once the semen evaporates, the sperm immediately exhibit good motility. If some factor interferes with the motility of the sperm, especially their forward movement, it will prevent the sperm from reaching the egg in a reasonable amount of time, making fertilization impossible. Sperm from azoospermia patients lack the ability to move quickly, and they cannot swim to the female uterus and combine with the egg cell.
