Article Abstract
This paper undertakes an investigation into the implications of premature progesterone rise (PPR) on pregnancy outcomes in freeze-all strategy cycles. A retrospective cohort study encompassing 675 IVF/ICSI cycles using a freeze-all strategy was enrolled. The cycles were categorized into two groups based on serum progesterone levels at the time of hCG administration: 526 cycles had levels below 1.5 ng/mL, while 149 cycles had levels equal to or above 1.5 ng/mL. The findings revealed a significantly higher number of mature follicles and retrieved oocytes in patients with PPR across all AMH categories. Multiple analyses revealed factors influencing PPR, including the duration of induction and the number of retrieved oocytes. Within the same oocyte retrieval number group, patients with PPR demonstrated non-inferior pregnancy outcomes compared to non-PPR patients. Upon adjustment for age, AMH, and total follicle-stimulating hormone (FSH) dosage, PPR maintained a positive correlation with the cumulative live birth rate (LBR). The study showed that PPR correlates with an increase in retrieved oocytes while maintaining similar embryo quality and oocyte retrieval rates and results in a higher cumulative LBR.

The use of gonadotrophin-releasing hormone (GnRH) agonist trigger in GnRH antagonist cycles in fertilisation (IVF) with elective freeze-all strategy is known to practically eliminate the risk of severe ovarian hyperstimulation syndrome (OHSS). Still, there are few case reports of early-onset severe OHSS development after agonist use for final oocyte maturation. This patient presented in an emergency on post-Ovum pickup (OPU) day 5 with complaints of cough with chest pain.

Objective: To investigate the impact of embryo cryopreservation duration on the clinical pregnancy rate (CPR) and live birth rate (LBR) in women undergoing their first frozen embryo transfer (FET) following the freeze-all strategy.
Methods: This multicenter retrospective study included 32 838 women who were patients at the five large-scale assisted reproduction treatment (ART) centers in China. The subjects were divided into seven groups according to the duration of embryo cryopreservation, among which the CPRs and LBRs were compared.
A comparative analysis of progestin-primed ovarian stimulation versus GnRH antagonists protocols pertaining to stimulation parameters and embryological outcomes in patients with endometrioma.

Research Question: Do embryo parameters and live birth rates differ between patients with endometrioma undergoing a freeze-all strategy using either GnRH antagonists or progestin-primed ovarian stimulation (PPOS)?
Design: This retrospective cohort study was conducted at Bahceci Health Group from January 2021 to January 2023. Inclusion criteria were females aged 20-40 with confirmed endometriosis, using either GnRH antagonists or PPOS ovarian stimulation, and opting for freezing all embryos without fresh embryo transfer (ET). A total of 543 patients were analyzed, with the primary outcome being usable embryos at cleavage stage and secondary outcomes including distribution of embryo quality, clinical pregnancy, and live birth rate.

Study Question: Does female or male hepatitis B virus (HBV) infection affect the oocyte and embryo quality, pregnancy outcomes, and neonatal outcomes in infertile couples undergoing ART treatment?
Summary Answer: The female or male HBV infection did not have a statistically significant negative impact on the development of oocytes and embryos, pregnancy outcomes, or neonatal outcomes of ART.
What Is Known Already: Only few studies assessing the effects of HBV infection on the reproductive outcomes among infertile population have been conducted with inconsistent results. There is limited research that focuses on the oocyte and embryo development of HBV-infected females and males.

Purpose: To compare the clinical effectiveness and overall treatment cost of three ovarian stimulation protocols-dydrogesterone (DYD), medroxyprogesterone acetate (MPA), and GnRH antagonist-in women undergoing in vitro fertilization (IVF).
Methods: This prospective, multicenter cohort study was conducted at two IVF units from March 2023 to March 2024. A total of 307 women undergoing IVF were divided into three groups based on their pituitary suppression protocol: DYD (n = 99), MPA (n = 101), and GnRH antagonist (n = 107).
