The severing of the testicular ducts is a very reliable form of contraception. It prevents the sperm cells from reaching the seminal fluid. This severing has no effect on the seminal fluid volume during ejaculation or on the potency.

While this method is very reliable it has the disadvantage that it can only be reversed in certain conditions. If a desire for pregnancy occurs after a vasectomy the man has two alternatives:

  • Reconstruction of the spermatic duct: The urologist can attempt to repair the severance through a reconstruction of the testicular ducts. If the operation is successful the man can achieve a pregnancy via intercourse.
  • TESE / MESA: The sperm cells are obtained directly from the epididymis or the testicular tissue. In this case, the amount of obtained sperm cells is usually very small. A treatment with in vitro fertilization (IVF) is necessary to achieve a pregnancy.

IMPORTANT: If the TESE or MESA techniques are employed, then sperm cells must be inserted into the cell plasma of the egg cell via the Microinjection method (ICSI).  This is due to the fact that usually only a few sperm cells are obtained from the extraction.

A diagnosis of azoospermia is, at first, a shock to most patients.  Fortunately, with the aid of the above-mentioned methods we can help patients fulfill their wish for a child.  In this process, we count on our experience, on our team, and on collaborative work with andrologists.

Sometimes, however, no sperm cells can be found. In this case, there is the possibility to use “third-party” sperm cells. While it is a possibility, the use of donor sperm is heavily regulated in most countries.
