MALE INFERTILITY
Overview of Male Infertility
Nearly 1 in 7 couples face infertility, meaning they have been unable to conceive a child despite regular, unprotected intercourse for a year or longer. Male infertility is a significant factor in up to half of these cases. Male infertility can result from various factors, such as low sperm production, abnormal sperm function, or blockages that prevent sperm delivery. Illnesses, injuries, chronic health conditions, lifestyle choices, and other factors may contribute to male infertility.
Symptoms of Male Infertility
The main sign of male infertility is the inability to conceive a child. However, some individuals may experience the following signs and symptoms:
- Problems with sexual function, such as difficulty with ejaculation, reduced sexual desire, or 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
- 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)

- Ejaculation issues, such as retrograde ejaculation
- Anti-sperm antibodies attacking sperm
- Tumors affecting reproductive organs
- Undescended testicles
- Hormone imbalances
- Tubal defects or blockages
- Chromosome defects like Klinefelter’s syndrome
- Sexual intercourse problems (erectile dysfunction, premature ejaculation)
- Celiac disease
- Certain medications or prior surgeries
Environmental Causes of Male Infertility
Exposure to certain environmental factors can also contribute to male infertility, including:
- Industrial chemicals
- Heavy metal exposure
- Radiation or X-rays
- Overheating of the testicles (saunas, hot tubs, tight clothing)

Health, Lifestyle, and Other Causes
Additional factors that may contribute to male infertility include:
- Drug use (anabolic steroids, cocaine, marijuana)
- Alcohol consumption
- Tobacco smoking
