Duration of cryostorage is not associated with rates of thaw survival, fertilization, blastulation and ploidy, or pregnancy outcomes of vitrified human oocytes.

Purpose: This study is to evaluate duration of oocyte cryostorage and association with thaw survival, fertilization, blastulation, ploidy rates, and pregnancy outcomes in patients seeking fertility preservation.

Methods: Retrospective cohort study to evaluate clinical outcomes in patients who underwent fertility preservation from 2011 to 2023 via oocyte vitrification for non-oncologic indications. Primary outcome was thaw survival rate.

An Analysis of Fertility Preservation Offerings for Transgender Youth on United States Pediatric Hospital Websites.

Purpose: To survey United States (U.S.) pediatric hospital websites for information about fertility preservation (FP) for transgender patients.

Spironolactone use and oocyte maturation in patients undergoing controlled ovarian hyperstimulation.

Purpose: To evaluate the association between spironolactone use and controlled ovarian hyperstimulation (COH) outcomes.

Methods: Retrospective study, including patients who underwent COH. Oocyte yield and maturation rates were compared by categories of spironolactone use at the start of their cycle.

Effect of various contraceptives on oocyte yield and maturation in patients undergoing planned oocyte cryopreservation.

Research Question: Do the various forms of hormonal and non-hormonal contraceptives have any association with ovarian stimulation outcomes, such as oocyte yield and maturation, in patients undergoing planned oocyte cryopreservation (POC)?

Design: This retrospective cohort study included all patients who underwent POC cycles between 2011 and 2023. The use of types of contraception before a POC cycle was recorded. The study evaluated the median number of cumulus-oocyte complexes obtained after vaginal oocyte retrieval and the proportion of metaphase II oocytes that underwent vitrification among all the cohorts.

Obstetric outcomes of nulliparous women with pelvic pain undergoing fertility treatment.

Research Question: Is there any association between pelvic pain and primary caesarean delivery for patients undergoing assisted reproductive technology (ART) treatment?

Design: Retrospective cohort study of nulliparous patients with singleton pregnancies who underwent ART treatment and achieved a live birth between 2012 and 2020. Cases included patients diagnosed with pelvic pain. A 3:1 ratio propensity-score-matched population of patients without a history of pelvic pain was included as the control group.
