Male infertility is one of the main causes of difficulty in achieving pregnancy in about half of couples. Reproductive issues in men can stem from problems related to sperm production, function, and transport.
Causes of Male Infertility
1. Sperm Production Issues:
Varicocele: This condition involves the enlargement of veins in the testicles, leading to increased temperature in the testicular area, which can negatively affect sperm production.
Cryptorchidism: This condition refers to the failure of the testes to descend into the scrotum, which can affect sperm production and decrease pregnancy rates.
Hormonal Imbalances: Conditions like testosterone deficiency and other hormonal imbalances can reduce sperm production.
2. Sperm Function Disorders:
Klinefelter Syndrome: This genetic condition can affect sperm production.
Anti-Sperm Antibodies: These are immune system defense mechanisms that may mistakenly recognize sperm as foreign particles and attack them.
Infections: Various infections, such as epididymitis, can impair sperm function and block ducts.
3. Sperm Transport Problems:
Blockages: Congenital or acquired blockages in ducts such as the vas deferens can interfere with sperm transport and decrease pregnancy chances.
Premature or Delayed Ejaculation: These conditions can also affect sperm transport.
Diagnostic Methods
- Semen Analysis: This test evaluates sperm count, motility, and morphology. Low sperm count or motility may indicate infertility.
- Hormonal Tests: Measuring testosterone and other hormone levels can help identify hormonal imbalances.
- Genetic Tests: These tests detect chromosomal abnormalities and other genetic factors, such as Y chromosome deletions.
- Testicular Biopsy: A small sample of testicular tissue is taken to directly observe sperm production and maturation, and to evaluate the structure and count of sperm.
- Imaging Tests: Techniques like ultrasound and MRI are used to identify structural problems in the reproductive organs and detect blockages.
