· You must produce healthy sperm. Initially, this involves the growth and formation of the male reproductive organs during puberty. At least one of your testicles must be functioning correctly, and your body must produce testosterone and other hormones to trigger and maintain sperm production.
· Sperm have to be carried into the semen. Once sperm reproduced in the testicles, delicate tubes transport them until they mix with semen and are ejaculated out of the penis.
· There needs to be enough sperm in the semen. If the number of sperm in your semen (sperm count) is low, it decreases the odds that one of your sperm will fertilize your partner's egg. A low sperm count is fewer than million sperm per milliliter of semen or fewer than 39 million per ejaculate.
· Sperm must be functional and able to move. If the movement(motility) or function of your sperm is abnormal, the sperm may not be able to reach or penetrate your partner's egg. Problematical with male fertility can be caused by a number of health issues and medical treatments.Some of these include:· Varicolored. Varicolored is a swelling of the veins that drain the testicle. It's the most common reversible cause of male infertility. Although the exact reason that varicolored cause infertility is unknown, it may be related to abnormal testicular temperature regulation. Varicolored result in reduced quality of the sperm. Treating the varicolored can improve sperm number sand function, and may potentially improve outcomes when using assisted reproductive techniques such as in vitriol fertilization.
· Infection. Some infections can interfere with sperm production or sperm health or can cause scarring that blocks the passage of sperm. These include inflammation of intrepidity (epidemiologist) or testicles (bronchitis) and some sexually transmitted infections, including gonorrhea or HIV. Although some infections can result impermanent testicular damage, most often sperm can still be retrieved.
· Ejaculation issues. Retrograde ejaculation occurs when semen enters the bladder during orgasm instead of emerging out the tip of the penis. Various health condition scan cause retrograde ejaculation, including diabetes, spinal injuries,medications, and surgery of the bladder, prostate or urethra.Some men with spinal cord injuries or certain diseases can't ejaculate semen, even though they still produce sperm. Often in these cases sperm can still be retrieved for use in assisted reproductive techniques.
