Les stimulations ovariennes modérées pour fécondation in vitro constituent-elles un réel progrès en assistance médicale à la procréation ?

[Preliminary study on the experience of egg donors at the CHRU in Tours: Key features for future research]

OBJECTIVES

This exploratory survey aims to identify the obstacles to egg donation (ED), based on the donors' experience. Despite 30 years of practice and awareness-raising campaigns, ED in France suffers from a shortage of female donors due to a lack of knowledge of this donation (Agence de la biomédecine, 2017).

METHOD

Qualitative study by semi-directive interviews conducted between January and August 2018 at the CHRU in Tours with 15 egg donors in the postoperative period.

RESULTS

The donation generated a sense of pride and personal accomplishment among the donors, in contrast to the lack of recognition of their actions by professionals and their entourage. Physical commitment does not seem to be a barrier to donation. The organisational and logistical constraints were identified as one of the main obstacles, while 70% of the interviewees stressed the benevolence of the practitioners. Finally, the donation opened up questions for them on female fertility, maternity and the role of gender norms in gamete donation.

CONCLUSION

The survey reveals the technical dimension of ED imposed by the biomedical system deplored by donors, and highlights the need to recognize their actions. Physical engagement is not a major obstacle, unlike organizational and relational aspects. This study opens up an important field of investigation, which should be explored in particular in the perspective of a French bioethical reform of ED.

Mild ovarian stimulation with clomiphene citrate launch is a realistic option for in vitro fertilization

OBJECTIVE

To validate the use of clomiphene citrate in IVF when mild stimulation approaches are chosen to reduce patient discomfort, risk, and cost.

DESIGN

Prospective cohort study.

SETTING

Private IVF clinic.

PATIENT(S)

A total of 163 patients undergoing IVF and with a good prognosis (defined as ≤38 years old with normal ovarian reserve and normovulatory cycles, body mass index <29 kg/m(2), no previous assisted reproductive technology cycles, no severe endometriosis, no history of recurrent miscarriage, no endocrine/autoimmune diseases, and no surgical semen extraction).

INTERVENTION(S)

Mild stimulation using a fixed protocol of clomiphene citrate (100 mg/d from cycle days 3 to 7) in combination with low doses of gonadotropins (150 IU of recombinant FSH on cycle days 5, 7, and 9) and GnRH antagonist.

MAIN OUTCOME MEASURE(S)

The cumulative delivery rate per patient after three fresh and/or frozen embryo transfers and time to pregnancy.

RESULT(S)

No dropouts were observed. The cumulative delivery rate was 70%, and the mean time to pregnancy was 2.4 months.

CONCLUSION(S)

Mild stimulation using clomiphene citrate in combination with low doses of gonadotropins can be considered a realistic option for good-prognosis patients undergoing IVF.

Metabolite Profiling in the Pursuit of Biomarkers for IVF Outcome: The Case for Metabolomics Studies

Background. This paper presents the literature on biomarkers of in vitro fertilisation (IVF) outcome, demonstrating the progression of these studies towards metabolite profiling, specifically metabolomics. The need for more, and improved, metabolomics studies in the field of assisted conception is discussed. Methods. Searches were performed on ISI Web of Knowledge SM for literature associated with biomarkers of oocyte and embryo quality, and biomarkers of IVF outcome in embryo culture medium, follicular fluid (FF), and blood plasma in female mammals. Results. Metabolomics in the field of female reproduction is still in its infancy. Metabolomics investigations of embryo culture medium for embryo selection have been the most common, but only within the last five years. Only in 2012 has the first metabolomics investigation of FF for biomarkers of oocyte quality been reported. The only metabolomics studies of human blood plasma in this context have been aimed at identifying women with polycystic ovary syndrome (PCOS). Conclusions. Metabolomics is becoming more established in the field of assisted conception, but the studies performed so far have been preliminary and not all potential applications have yet been explored. With further improved metabolomics studies, the possibility of identifying a method for predicting IVF outcome may become a reality.
