Here are medical issues which cause infertility:

1.    Varicocele. It's the most common reason for infertility in men, which appears as a poor quality of sperm.

2.    Ejaculation issues.  The problems with ejaculation happen when semen is ejaculated into the bladder rather than out through the urethra.  Men who have these problems usually notice that the urine becomes cloudy after ejaculation, and their ejaculation volume is small. This disorder may be treated with medicines.

3.    Infection.  Such infections as tuberculosis,  mumps, gonorrhea,  brucellosis, typhoid, smallpox,  influenza and syphilis cause low sperm count. In addition to that,  STDs like chlamydia and gonorrhea also cause infertility by blocking the epididymis or tubes. 

4.    Anti-sperm antibodies. These are immune system cells which determine the sperm as harmful by mistake. Thus they eliminate it.


5.    Hormone imbalances. Infertility can be a result of disorders in various hormone systems such as the pituitary, the hypothalamus, thyroid and adrenal glands.

6.    Defects of tubules which transport sperm.  The tubules that carry sperm may be blocked because of the trauma or abnormal development, injury from surgery and prior infections.

7.    Problems with sexual intercourse.  Such issues include erectile dysfunction, painful intercourse, premature ejaculation and psychological problems. Relationship problems which connected with sex also may cause infertility.

8.    Prior surgeries.  Such surgeries as inguinal hernia repairs,  prostate surgeries, vasectomy, scrotal or testicular surgeries, and large abdominal surgeries prevent men from having sperm in the ejaculate. 

9.    Certain medications. Long-term anabolic steroid use, testosterone replacement therapy, chemotherapy, some ulcer drugs, certain antifungal medications can worsen sperm production.

10.    Celiac disease.  If you are sensitive to gluten, celiac disease may cause infertility. However, it will be prevented if you adopt a gluten-free diet.

4.    Tobacco smoking. Smokers are most likely to have the reduced number of sperm.

5.    Overweight. It causes hormone changes and can impact the sperm directly.


6.    Stress. Long stress is connected with certain hormones which are necessary for sperm production, therefore emotional stress effects sperm quantity.

7.    X-Rays or radiation. High doses of radiation reduce the production of sperm.

8.    Sitting lifestyle and wearing tight clothes. These factors increase the temperature in your scrotum and may decrease the production of sperm.

9.    Frequent use of saunas and hot tubs. High temperatures impair sperm function and production, and its quantity might be reduced.

10.    Industrial chemicals. Exposure to pesticides, toluene, xylene, organic solvents,  herbicides and painting materials may reduce the sperm volume.
