Male factor in infertility

In couples with infertility, the probability of it being caused by the male factor can vary between 25% and 40%.
Causes of male infertility; Sperm structure, deformities (oligoaztenospermia) and decreases in sperm count (azoospermia, oligospermia) Among the problems that cause sperm structure disorders, varicocele is at the forefront and can be seen in 40% of infertile couples.
Varicocele is abnormal enlargement of testicular veins. As a result, blood flow slows down, temperature increase occurs and sperm movements can be affected. Varicocele is detected and graded during the examination, abnormalities seen in the spermiogram will accompany the examination findings. If there are clinical complaints, the operation can be planned due to varicocele. It has been reported in scientific studies that varicocele operation does not increase pregnancy rates in men who apply for infertility treatment and have severely low number and mobility in their spermiogram.
If children with undescended testicles are detected late and they are not operated within 1 year after birth, disorders in the sperm structure will occur in the following years and they will be among the causes of male factor-related infertility in adulthood.
Past testicular infections (mumps orchitis, orchitis), sexually transmitted diseases cause infertility in men by causing stenosis and obstruction in the reproductive canals.
Chromosomal disorders, defects in the regions of sperm production in the Y chromosome of males can be shown as genetic causes. Genetic causes are found in 10-15%. For this reason, chromosome analysis can be done with the blood sample taken from men during the research phase.
Both testicular tumors and chemotherapy and radiotherapy used in their treatment can cause temporary or permanent infertility by damaging sperm production. However, the sperm to be taken before these treatments can be frozen and stored, and it will be possible to have a child with microinjection in the future.
Liver, kidney diseases, alcohol, smoking, drug use, pituitary diseases, nervous system diseases, diseases with high fever can cause male infertility by disrupting sperm production.
Cystic Fibrosis is a genetic disease that causes obstruction in the sperm ducts and leads to infertility. Again, sexually transmitted diseases, testicular traumas, previous genital surgery operations, prostate cysts or masses are among the causes that cause infertility by causing obstruction in the sperm ducts.
While diabetes, nervous system diseases, previous urinary incontinence or bladder operations cause retrograde ejaculation, infertility occurs in men due to reflux of sperm.
Tests to reveal the causes of male infertility, especially spermiogram (after 3-5 days of sexual abstinence), hormone tests (FSH, LH, total testosterone, prolactin), testicular ultrasonography, genetic tests (chromosome analysis), semen and urine cultures and testicular biopsy.
