Aim: To evaluate the pregnancy rate in Japanese women treated with levonorgestrel for emergency contraception.
Methods: This retrospective record-based medical study included 1000 women who visited our clinic for emergency contraceptive treatment with 1.5 mg single-dose oral levonorgestrel, followed by 50 μg hormonal oral contraceptive from May 2011 to December 2017. The outcomes of the emergency contraceptive treatment were recorded at a follow-up visit, and descriptive statistics were obtained.
Results: The number of women treated with levonorgestrel at the clinic increased from 2011 to 2015, but there was no subsequent increase thereafter. Most women were in their 20s (57.4%), followed by their 30s (19.3%) and teens (18.3%). Of the 1000 women treated with levonorgestrel, 659 were followed up. Among the 659 women with follow-up data, 16 were pregnant (2.4%), of whom 11 underwent abortions, three had miscarriages, and two delivered at term. The timing of unprotected sexual intercourse relative to the estimated ovulation date among the pregnant women ranged from -3 to 23 days. The most commonly used contraceptive method before the emergency contraceptive visit was condoms (89.3%, 887/993). No new safety concerns were identified throughout the study period.
Conclusion: The pregnancy rate after levonorgestrel treatment in Japanese women was low, and similar to that reported in previous studies. Information on contraceptive methods and emergency contraception with levonorgestrel needs to be better disseminated among women of childbearing age.

Objective: We investigated whether the addition of a luteal phase support drug benefits pregnancy and perinatal outcomes in modified natural-cycle frozen-thawed embryo transfer (mNC-FET) for women up to the age of 35 years.
Methods: We analyzed the clinical data of 3658 mNC-FET cycles of women up to the age of 35 years from the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from January 2018 to December 2020 in a retrospective cohort study. The cycles were divided into three groups based on the luteal phase support protocol used.

Background: The diagnosis of depression or anxiety treated by SSRIs has become relatively common in women of childbearing age. However, the impact of gestational SSRI treatment on newborn thyroid function is lacking. We explored the impact of gestational SSRI treatment on newborn thyroid function as measured by the National Newborn Screening (NBS) Program and identified contributory factors.

Infertility has emerged as a significant global health concern. Assisted reproductive technology (ART) assists numerous infertile couples in conceiving, yet some experience repeated, unsuccessful cycles. This study aims to identify the pivotal clinical factors influencing the success of fresh embryo transfer of in vitro fertilization (IVF).

Objective: There is an increase in the application data of Extracorporeal Membrane Oxygenation (ECMO) in perinatal women, particularly since the outbreak of coronavirus disease 2019. Therefore, we reviewed publications on the use of ECMO in pregnant and postpartum women and analyzed the maternal and fetal outcomes, updated the progress of ECMO in perinatal women.
Methods: We conducted a systematic literature search across PubMed, EMBASE, Cochrane Library, and the International Clinical Trials Registry (ICTRP), yielding 30 eligible clinical studies that investigated the application of ECMO during pregnancy.

Objective: To test the hypothesis that a freeze-all strategy would increase the chance of live birth compared with fresh embryo transfer in women with low prognosis for in vitro fertilisation (IVF) treatment.
Design: Pragmatic, multicentre, randomised controlled trial.
Setting: Nine academic fertility centres in China.
