Fertilization happens when a sperm cell meets an egg cell in the fallopian tube. This process is successful when both sperm and egg are healthy. Sperm mobility is one of the necessary conditions of a good conception. However, other factors such as semen volume, sperm count, and sperm morphology (shape) are also important.
Male infertility accounts for about 40 to 50 percent of all infertility problems. This problem affects about 7% of men and is usually due to defects in semen as well as semen quality.
In 50% of infertile couples, the cause of infertility is the male partner. Low sperm count, abnormal sperm shape, and low sperm motility are men's leading causes of infertility.
Semen analysis is a crucial fertility test through which the sperm’s count, shape, size, and motility are evaluated. Also, in a spermogram, factors such as the volume of the semen, liquefaction, etc., are measured.
Azoospermia is defined as a medical condition in which a man has no measurable sperm in his ejaculate (semen). It may be caused by hormonal problems, genetic disorders, etc.
Testicular biopsy involves removing a small piece of testicle to check for sperm production. The process of producing sperm takes place in the seminiferous tubules in the testicles.
Several factors are involved in male infertility, which are either related to the sperm production or the sperm transfer. Fortunately, even if the male partner lacks sperm (azoospermia), he can be a father through a new and advanced method of third-party reproduction, i.e., IVF with sperm donor.
