Double heterologous IVF-ET entails the use of a male donor of semen and a female donor of ovules. This technique is indicated in the case of both male and female infertility.
The double heterologous IVF-ET technique includes a phase of preparation of the uterus for the woman in order to allow for accepting the embryo fertilised with the male donor’s semen. The oocytes coming from the female donor are fertilised in vitro with the male donor’s spermatozoa, after which the embryos are transferred into the patient’s uterus.
This procedure is indicated in specific cases of female infertility (depletion of the ovarian function, early physiological menopause, surgical menopause with removal of the ovaries, genetic diseases transmittable to offspring, repeated failures with other assisted fertilisation techniques, repeated failures of embryonic nesting, and endometriosis), and serious male infertility.
