Andrology (Infertility)

Infertility affects about one in six couples – and in up to 50% of cases, the cause lies with the man
Male infertility can result from a variety of causes, including hormonal imbalances, anatomical issues, or genetic factors. Andrology offers modern diagnostic tools and effective treatments. In our practice, we thoroughly investigate the underlying causes and provide discreet, personalized counseling on the best available options. Learn more about diagnostic procedures and therapies.

What does male infertility mean?

Wenn trotz regelmäßigem ungeschützten Geschlechtsverkehrs über ein Jahr keine Schwangerschaft eintritt, spricht man von Unfruchtbarkeit (medizinisch: Infertilität). Beim Mann liegt die Ursache oft in der Anzahl, Beweglichkeit oder Form der Spermien.

What are possible causes of infertility?

  • Hormonal disorders (e.g. testosterone deficiency)
  • Varicocele (varicose veins in the testicles)
  • Inflammation (e.g., of the epididymis)
  • Genetic causes
  • Undescended testicles in childhood
  • Environmental factors (e.g., heat, nicotine, alcohol, pollutants)
  • Medications or previous cancer treatments

How does the examination work?

First, a detailed medical history (anamnesis) is taken, followed by:

  • Semen analysis (spermiogram): Examination of sperm quality (count, motility, shape)
  • Hormone profile: Blood test to check levels of testosterone, FSH, and LH
  • Ultrasound of the testicles
  • Testing for infections

If any abnormalities are found, we refer the patient to a specialized expert for further evaluation and treatment.

Can infertility be treated?

Yes – depending on the cause:

  • Hormonal therapies for hormone deficiency
  • Surgery for varicocele
  • Antibiotics for infections
  • Artificial insemination (e.g., ICSI) for severely impaired sperm quality

FAQ - About Male Infertility

Can you become a father despite poor sperm quality?

Yes. Depending on the cause, there are treatment options – from hormonal support to surgical procedures to assisted fertilization (e.g., ICSI). Fatherhood is possible even with severely impaired sperm quality.

How much sperm is normal, and how important is the amount?

The normal ejaculate volume is between 1.5 and 6 milliliters. However, not only the amount is important, but above all the number, motility, and shape of the sperm.

Can stress cause infertility?

Yes. Chronic stress can disrupt hormonal balance, affect sperm production, and negatively impact libido and erection.

How does age affect male infertility?

In men, fertility also declines with age – from around the age of 40, sperm quality and motility decline significantly, and the risk of genetic changes increases.
