Hernia. If not treated immediately, it can damage the vas deferens, the tube in which the sperm travels through.
Erectile dysfunction (ED)
This is one of the most obvious infertility warning signs among men. It is the inability to maintain an erection firm enough for intercourse. This condition affects at least 30 million males. In most cases, ED relates to hormonal imbalances. Other causes include:
Venous leak. A venous leak occurs when the blood vessels do not constrict enough to keep the blood in during sexual arousal.
Anxiety and stress. Studies show that psychological factors can affect a man’s sexual drive and performance.
Lifestyle choices. Alcohol, tobacco, and drugs contain ingredients that can affect the functionality of the reproductive organs.
Issues with semen
Difficulty in ejaculating during intercourse is one of the more observable male infertility warning signs. This is often a direct result of erectile dysfunction. The inability to ejaculate can indicate problems with sperm production as well as other health conditions such as diabetes and/or nerve problems. If a man is able to ejaculate, sometimes the problem lies in the quality of sperm. Usual causes are:
Genetic defects. Chromosomal abnormalities such as Down’s Syndrome and spina bifida can affect sperm quality.
Sexually transmitted infections (STIs). STIs like chlamydia and gonorrhea can cause infection in the reproductive organs and impair fertility by causing substantial damage in the sperm.
Medication. Some drugs and medications can cause male infertility. For example, anabolic steroids lower sperm quantity.
Exposure to heat and radiation. The testicles have a lower temperature compared to other organs. Subjecting them to heat or high doses of radiation can cause permanent damage to sperm production.
Other infertility warning signs in males include loss or thinning of hair, retrograde ejaculation, and enlarged breasts (gynecomastia).
