Successful ART outcome in a woman with McCune-Albright syndrome: a case report and literature review.

McCune-Albright syndrome (MAS) is a rare genetic disease affecting multiple organs, including endocrine tissues. This endocrinopathy is sometimes responsible for infertility, as it may induce an independent functioning of the ovaries leading to anovulatory cycles. This case report describes the infertility journey of a 22-year-old female who had early puberty and irregular periods with high estrogen and progesterone levels, low FSH and LH (on day 3 of her menstrual cycle), and a multi-cystic right ovary. She received several infertility treatments: initially in vitro oocyte maturation (IVM) followed by cyst transvaginal ultrasound-guided aspiration, all unsuccessful. A right hemi-ovariectomy was performed that eventually restored regular cycles and made it possible to perform ovarian stimulation (OS) and in vitro fertilization (IVF). Live birth was obtained after the first embryo transfer.

Investigation of the reliability of semi-automatic annotation by the Geri time-lapse system.

RESEARCH QUESTION: What is the reliability of Geri® Assess 2.0 software time-lapse technology for annotating kinetic events and identifying abnormal phenotypes in preimplantation human embryos? DESIGN: Embryos were annotated using Assess 2.0 for the appearance and fading of pronuclei, and for progression to the 2-, 3-, 4-, 5- and 6-cell stages and to three blastocyst stages. Identification of reverse cleavage and direct cleavage phenotypes was also recorded. Manual annotation was undertaken after these events in a blinded fashion. Embryo scores were compared between Assess 2.0 and manual annotation. RESULTS: A total of 513 oocytes from 34 women were included. Detection rates for Assess 2.0 versus manual annotation among the 10 kinetic events and including direct cleavage and reverse cleavage ranged between 0% and 94.4%. The percentage of discordant pairs was significantly different for all 12 events analysed (P-value range 0.036 to <0.0001). The sensitivity of Assess 2.0 ranged from 68.2% to 94.4% and specificity ranged from 63.8% to 97.3%. Assess 2.0 called for verification by the embryologist for at least one event in 55.2% of oocytes assessed. Of the 297 embryos scored by manual annotation, Assess 2.0 assigned the same score for only 125 (42.1%), although after manual corrections, concordance with manual annotation scores was raised to 66.0%. CONCLUSIONS: The results reveal striking differences between Assess 2.0 and manual annotation for kinetic annotations. Failure of Assess 2.0 to detect direct cleavage events and the low detection rate of reverse cleavage are further limitations. These collective findings highlight the importance of validating time-lapse annotation software before clinical implementation. Manual verification of Assess 2.0 outputs remains essential for accurate data interpretation.

Validation of the French IVF guidelines during the COVID-19 pandemic.

RESEARCH QUESTION: Is a symptom questionnaire as per the French IVF guidelines adequate for screening patients during the COVID-19 pandemic? DESIGN: Patients planning IVF from June 2020 to February 2021 were included in the study. In compliance with French IVF guidelines, all patients fever-free on the day of oocyte retrieval were screened for risk of COVID-19 by completing a symptom questionnaire after being counselled regarding the importance of a COVID-19-free medical practice. Patients with IVF planned between June and September 2020 only completed the questionnaire (group 1), while those planning IVF after September 2020 also underwent the RT-PCR test for SARS-CoV-2 RNA (group 2). Cycle cancellation rates between groups were compared. Group 1 patients consented for follicular fluid testing for SARS-CoV-2 and an interview after cycle completion to determine COVID-19 exposure during the 6 months before and after retrieval. RESULTS: Cycle cancellation rates for groups 1 and 2 were 0% (0/214) versus 1.4% (8/577), respectively, (P = 0.116). All 183 follicular fluid samples from group 1 were negative for SARS-CoV-2 RNA. Of 171 patients interviewed post-IVF, 16 (93.4%) developed COVID-19 symptoms or a positive real-time PCR (RT-PCR) RT-PCR test, but none within 2 months pre- or post-retrieval. CONCLUSIONS: These results provide reassurance that, consistent with the COVID-19 French IVF guidelines, use of a symptom questionnaire is effective in screening patients planning to undergo IVF. Failure to detect viral RNA in any follicular fluid sample does not negate the possibility that follicular fluid is a viral reservoir. However, the findings provide reassurance that the follicular environment in this study's carefully screened population was COVID-free.
