In the context of IVF, a few hours after oocyte retrieval from the woman engaged in a assisted reproduction procedure or from a donor, doctors perform in vitro fertilization with the sperm of a donor or the spouse. The next two days, they carefully monitor the formation of embryos. Count between 50 and 70% success at this stage.
Then comes D-Day. Doctors deposit one or two embryos in the recipient’s uterine cavity using a catheter (those that remain are frozen). You’re done with the practicality, but nothing is completely played out. As with all other women, you have to take into account the risk of miscarriage. The chances of pregnancy are around 50%.
To know : Doctors take about XNUMX oocytes at each puncture. Couples get about five. Several recipients can therefore benefit from the same donation! |
Artificial insemination with donor (IAD): how does it work?
THEartificial insemination with donor (IAD), as its name suggests, consists of depositing the sperm of an anonymous person in the recipient’s uterus, using a catheter. Of course, it is necessary to perform this intervention during ovulation to have a chance that the sperm meet the egg.
The success rate reaches around 20% for each insemination. Just like so-called “natural” procreation, IAD does not always work! Better to prepare for several consecutive failures … Almost 800 children are born each year from an IAD.
After six ADI attempts (the maximum number covered by social security), doctors can change their method and switch to IVF with donor sperm.
Receiving a donation takes a long time!
Lack of gamete donors, couples or single women wait a long time : one year, two years, often more before obtaining sperm and/or oocytes… Information campaigns regularly try to encourage potential donors. In 2010, for example, 1285 couples were awaiting egg donation. It would have taken 700 additional donations to meet the needs. And these waiting lists are likely to increase with the expansion of access to assisted reproduction and changes in the anonymity rules for gamete donors.
“When I was 17, I found out that I had Turner Syndrome and that I was infertile. But at that age, I did not know what awaited me the day I wanted to found my family… ”Séverine indeed waited for her marriage, nine years ago, to register at Cecos as demand for oocytes. “From there, we became aware of the extent of the difficulties“, She says. Better to be informed before starting: the wait is on average one year to obtain a sperm sample, between three and four years for oocytes!
«To reduce the delay, we were offered to bring a donor who will donate for someone else but would help us move up the waiting list. My sister-in-law agreed to donate her eggs, we thus won a year“, Explains the young woman. The practice no longer surprises anyone. At the Cecos de Cochin, in Paris, Prof. Kunstmann notes that 80% of donors are actually recruited through this means.
