Heterologous IVF-ET Switzerland

Male heterologous IVF-ET is a technique based on the in-vitro fertilisation of the eggs with the subsequent transfer of the embryo into the patient's uterus which foresees the resorting to the use of donor sperm due to serious infertility problems of the male partner of the couple. 

The male heterologous IVF-ET technique includes hormonal stimulation for the woman for inducing multiple growth of the follicles, followed by the collection of the oocytes, their in-vitro fertilisation with the sperm of a suitably selected donor, and the subsequent transfer of the embryos into the uterus. The additional embryos are cryopreserved (frozen) and remain available to the couple for any subsequent embryo transfers. 

This is a procedure indicated in specific cases of severe male infertility, azoospermia (absence of spermatozoa) or failure of techniques using the partner’s sperm.
