Male fertility is a complex process. For a pregnancy to occur, healthy production and transport of sperms are vital.
A male’s fertility potential can be affected by a number of conditions, such as:
Sperm production problems
These can be due to a number of factors such as an infection, undescended testes, genetic causes, testicular torsion, varicocele and damage as a result of medications, chemotherapy or radiation.
Blockage of sperm transport
This can be due to an infection, absence of the vas deferens as seen in cystic fibrosis, prior vasectomy or damage from previous surgery.
Hormonal problems
Hormonal problems involving the hypothalamus or pituitary can lead to low sperm production. Anabolic (androgenic) steroid abuse can suppress sperm production. Other conditions such as thyroid dysfunction, obesity and insulin resistance can also cause hormone disruption.
Sexual problems | Erection and ejaculation problems
This may be the result of premature ejaculation, failure of ejaculation, erectile dysfunction, spinal cord injury or damage to nerves.
Presence of sperm antibodies
Anti-sperm antibodies are immune system cells that mistakenly identify sperm as harmful invaders and attempt to eliminate them. Today, there are a number of assisted reproductive technology (ART) treatments available to overcome difficulty conceiving.
