Study on the clothing method

-

Lesbian couples can be both biological mothers through a new indication for IVF called CLOTHING, Receiving Oocytes of the Couple, so that one of them gives the eggs and the other becomes pregnant.

The purpose of this study is simply to present the new experiences produced in the CEFER Assisted Reproduction Institute in the formation of a new family model: two biological mothers, lesbians, where one of them provides the oocytes and the other is the one that serves to house the transferred embryo and get pregnant. The authors have called this new type of family, model ROPA (reception of oocytes by the couple). This is a pioneering fact in Spain and one of the first worldwide.

In countries where the ROPA technique is legal, it offers lesbians an easier way, which makes both partners participate to form a family, and the doctors who treat them, to be sensitized with the new family model.

Below you have an index with all the points that we will discuss in this article.

Introduction

The traditional model of family in the West (father, mother and children of both) has been greatly expanded to include single-parent families, children of different parents, adopted children and homosexual couples.

In some Western countries, women who do not have a male partner (single, divorced or widowed) or with a female partner (lesbians) have been able to have children from Artificial Insemination with donor sperm (IAD) more than 30 years ago. The inseminated woman's couple lacked any legal recognition of that family. The authors have been doing insemination with donor semen to women with these characteristics since 1977, when the semen bank was created in Spain.

Lesbian mothers

In Spain, in 2005, the rights of homosexual couples were equal to those of heterosexual couples (Law 13/2005). This law has made it possible for the two members of a lesbian couple to participate in the process and pregnancy if they wish: one would provide the oocytes that would be inseminated with semen from an anonymous donor, while the other receives the embryos and gestates them, in case of pregnancy occurrence. The authors call this technique ROPA (reception of oocytes from the couple).

The authors present the work done with 14 lesbian couples between February 2007 and June 2009, who resort to the ROPA technique. The first baby girl born through this technique was born in Spain through the aforementioned technique. The authors think that this technique is perfectly valid and ethical in Assisted Reproduction.

Description of the case

With the exception of legal and human aspects, the ROPA technique is comparable to an egg donation process. All the women involved in the process had to give their consent in writing.

Woman providing oocyte ovarian stimulation was carried out in those women who were to provide the oocytes to their partners with agonists of GnRH (Decapeptyl), recombinant FSH (Gonal F) and recombinant hCG (Ovitrelle). The monitoring was done through vaginal ultrasound along with measurements of estradiol in blood. Ovarian uptake was carried out at 36 hours after the administration of the recombinant hCG by transvaginal echoguided puncture with aspiration of the follicular fluid. An anonymous donor semen with proven fertility was selected and the technique of sperm microinjection (ICSI) was used to fertilize the oocytes. The woman receiving the embryos, the preparation of the endometrium was carried out by the administration of GnRH agonists and estrogens ( Progynova). The monitoring of the growth of the endometrium was carried out in the same way, by means of vaginal ultrasounds and blood extractions to check the serum levels of estradiol. The administration of progesterone (Utrogestan or Progeffik) started on the same day that the couple underwent follicular puncture. The embryo transfer was carried out on day +3 of embryo culture.

Fertility treatments in the couple: how to get pregnant?

According to the latest report of the Spanish Fertility Society (SEF), in 2016 were carried out 138,553 cycles of in vitro fertilization (IVF) and 36,463 cycles of artificial insemination (AI), which resulted in a total of 37,503 babies born . This represents an increase of 8% in the use of assisted reproduction techniques with respect to the previous year, which shows that more and more couples need help to have the opportunity to become parents. After a year of sexual intercourse without achieving pregnancy, a couple is considered to have sterility problems, so it is advisable to start doing diagnostic tests and determine the most appropriate assisted reproduction treatment in each case, as we will discuss throughout this post.
