Introduction: The aim of our study was to carry out a national survey of French practitioners to evaluate (i) their diagnostic criteria for making a diagnosis of unexplained infertility (UEI) and (ii) their management strategy when facing UEI.
Materials And Method: An online questionnaire comprising ten multiple-choice questions was sent by mail to French reproductive practitioners in 80 fertility centres.
Results: The response rate was 59.6% (195/327). Post coital testing was always or often prescribed by 14.8% of respondents (n = 36). Chlamydia trachomatis testing was never prescribed by 31.7% (n = 59) of them, 30.2% prescribed a pelvic MRI in cases of UEI and 18.4% (n = 33) always or often performed laparoscopy. For 87.6% (n = 169), advanced maternal age was always or often an indication of first-line IVF, with an average threshold of 37.4 years. For 68.6% (n = 129), diminished AMH was an indication for first-line IVF, with an average AMH threshold of 1.2 ng/ml. With respect to the management of UEI, we did not observe a consensus between the strategies of 2 to 6 intrauterine insemination cycles before IVF or IVF as the first-line treatment.
Conclusion: There is no consensus in France on what tests should or should not be carried out to conclude UEI, and there is also no consensus on the management of UEI. UEI is one of the top 10 priorities for future infertility research. The diagnostic criteria must be standardized to enable the comparison of studies on this topic as well as to improve the translation of research into clinical practice.

Reduced trophoblast migration and invasion contribute to unexplained recurrent spontaneous abortion (URSA). Aquaporin 3 (AQP3) plays a crucial role in facilitating trophoblast migration and invasion during early pregnancy through fetal-maternal crosstalk. This study aimed to comprehensively investigate the mechanism involving AQP3 and its modulatory effects on human extravillous trophoblast (HTR-8/SVneo cells) migration and invasion.

Background: Over the past five years, the pregnancy rate in assisted reproductive technology (ART) programs in Russia has remained relatively stable. The aim of this study was to assess the distribution of monocyte and macrophage subsets in the blood and follicular fluid of infertile women undergoing assisted reproductive technology.
Methods: The study involved 45 women with a mean age of 35 ± 4.

Background: Numerous pathogenic variants causing human oocyte maturation arrest have been reported on the primate-specific TUBB8 gene. The main etiology is the dramatic reduction of tubulin α/β dimer, but still large numbers of variants remain unexplained.
Methods: Using microinjection mRNA and genome engineering to reintroduce the conserved pathogenic missense variants into oocytes or in generating TUBB8 variant knock-in mouse models, we investigated that the human deleterious variants alter microtubule nucleation and spindle assembly during meiosis.

Background: Intrauterine insemination (IUI) is an effective and inexpensive method of managing patients with unexplained and male factor infertility. It is attempted before proceeding to more invasive assisted reproductive techniques such as fertilisation and intracytoplasmic sperm injection. Numerous semen parameters have been assessed to indicate successful outcomes with IUI.

Background: Chromosomal mosaicism, a phenomenon observed in a minority of embryos, showcases its prevalence and inherent unpredictability, leading to variations in embryo mosaic rates across different centers. This research endeavors to assess the prevalence of mosaicism and its characteristics within the scope of our preimplantation genetic testing-A (PGT-A) services in Indonesia. Specifically focusing on our center's experience since 2020, this study aims to elucidate mosaic rates among embryos in our care.
