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.

  • 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.
