Male Infertility & Sexual Dysfunction

nfertility affects up to 12% of all men, and sexual dysfunction occurs frequently in men of reproductive age, causing infertility in some instances. In infertile men, hypoactive sexual desire and lack of sexual satisfaction are the most prevalent types of sexual dysfunction, ranging from 8.9% to 68.7

Symptoms

The main sign of male infertility is the inability to conceive a child. There may be no other obvious signs or symptoms.

In some cases, however, an underlying problem such as an inherited disorder, hormonal imbalance, dilated veins around the testicle or a condition that blocks the passage of sperm causes signs and symptoms. Signs and symptoms you may notice include:

  • Problems with sexual function — for example, difficulty with ejaculation or small volumes of fluid ejaculated, reduced sexual desire, or difficulty maintaining an erection (erectile dysfunction)
  • Pain, swelling or a lump in the testicle area
  • Recurrent respiratory infections
  • Inability to smell
  • Abnormal breast growth (gynecomastia)
  • Decreased facial or body hair or other signs of a chromosomal or hormonal abnormality
  • A lower than normal sperm count (fewer than 15 million sperm per milliliter of semen or a total sperm count of less than 39 million per ejaculate)

When to see a doctor

See a doctor if you have been unable to conceive a child after a year of regular, unprotected intercourse or sooner if you have any of the following:

  • Erection or ejaculation problems, low sex drive, or other problems with sexual function
  • Pain, discomfort, a lump or swelling in the testicle area
  • A history of testicle, prostate or sexual problems
  • A groin, testicle, penis or scrotum surgery
  • A partner over age 35
 

Causes

Male fertility is a complex process. To get your partner pregnant, the following must occur:

  • 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 are produced 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 15 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.
