BACKGROUND: Compared with overnight insemination, it remains uncertain whether short-term insemination can improve outcomes in poor responders, and few studies have used cumulative live birth rate as the primary endpoint. The study aims to …

PURPOSE: To compare the clinical outcomes of extremely poor responders with one or two oocytes who receive in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). METHODS: A retrospective study was carried out on 2572 pat…

BACKGROUND: Low-dose aspirin is one of the widely used adjuvants in assisted reproductive technologies with the hope of improving the live birth rate. However, the studies regarding its effects are conflicting. The study aimed to investigat…

PURPOSE: To evaluate the contribution of the cleavage stage morphological parameters to the prediction of blastocyst transfer outcomes. METHODS: A retrospective study was conducted on 8383 single-blastocyst transfer cycles including 2246 f…

OBJECTIVE: To investigate whether using Zishen Yutai Pills (ZYP) following embryo transfer would affect the live birth rate in frozen-thawed embryo transfer (FET) cycles. METHODS: A retrospective analysis was performed on 15044 FET cycles …

STUDY QUESTION: What was the performance of different pretreatment prediction models for IVF, which were developed based on UK/US population (McLernon 2016 model, Luke model, Dhillon model, and McLernon 2022 model), in wider populations? S…

BACKGROUND: Oocyte degeneration was mostly described in intracytoplasmic sperm injection (ICSI) cycles; there is no report showing the relationship between oocyte degeneration and clinical outcomes in conventional in vitro fertilization (IV…

Background: Male and female gametes factors might contribute to the total fertilization failure (TFF). In first in vitro fertilization (IVF) cycles, decision-making of insemination protocol was mainly based on semen quality for the contribu…
