Poor ovarian response (POR) constitutes a notable clinical challenge within the domain of assisted reproductive technology, primarily attributable to the lack of reliable biomarkers for precise diagnosis and treatment. This study reveals si…

This study investigates the correlation between different ovarian reserves and the oocyte fertilization rate as well as early embryo development in the Changde area. A total of 325 infertile women who underwent in vitro fertilization proced…

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…

OBJECTIVES: The study was designed to investigate the correlation between body mass index (BMI) along with both ovulation effect and clinical pregnancy rate in patients with polycystic ovary syndrome (PCOS), as well as to analyze the factor…

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 …

AIM: To compare the therapeutic efficacy of ultrasound-guided high-intensity focused ultrasound (USgHIFU) in the treatment of adenomyosis with different signal intensity (SI) on T2-weighted images (T2WI). METHODS: A total of 299 adenomyosi…

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…

OBJECTIVE: To evaluate the effect of different levels of physician experience on the high-intensity focused ultrasound (HIFU) ablation of uterine fibroids and to provide a reference for the use of non-perfused volume ratio (NPVR) standards …

OBJECTIVE: To evaluate the experience of the physician of the technical success in high-intensity focused ultrasound (HIFU) ablation of uterine fibroids with a nonperfused volume ratio (NPVR) of at least 80%. METHODS: Patients from a 20-ce…
