For insemination, the sperm cells are placed at the ideal time directly into the uterine cavity. In this way, more sperm cells can reach the egg cells quicker, unlike in a natural insemination.

In order for insemination to be carried out at the perfect time, ovulation has to be ascertained either by using ultrasound or by using LH-urinary tests. The sperm cells, which are handed in on the day of the insemination, are prepared using modern techniques and are then placed directly into the uterus using a fine catheter.


  • Reproductive limitations of the male partner
  • “Antibodies” in the mucous of the cervix, which causes the sperm cells to die off and thus blocks the way to the egg cells
  • Desire to have children for lesbian couples.

In both cases, the cycle is monitored using ultrasound examinations. In some cases, an injection is needed to “trigger” ovulation. During a natural cycle this can be determined at home using a urinary test. In order to achieve better results, insemination can be carried out in a stimulated cycle.

In a heterologous insemination, the partner’s sperm is not used, but a donor’s sperm. This is necessary when no sperm cells are available (medical reasons, eg azoospermia, vasectomy). Lesbian couples who wish for children can also undergo a heterologous insemination.

The success rate is very dependent on the quality of the sperm and on possible support using hormonal stimulation. In addition, we recommend carrying out a fallopian tube test. If the fallopian tubes are blocked or not functioning, the sperm cells cannot reach the egg cells. In the Kinderwunschzentrum an der Wien we offer the HyCoSy method to check the fallopian tube function.

  • Side-effects of hormonal stimulation
  • Development of too many follicles, leading to termination of the treatment (risk of multiple birth)
  • In very rare cases after insemination, an infection of the uterus can occur.
