The aim of this study was to investigate whether the Fas system was involved in cryopreservation process of the human ovarian tissue. Human ovarian cortical tissues were cryopreserved using slow freezing method. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) was used to investigate apoptosis of primordial follicle. Fas, Fas ligand and active caspase-3 expression were detected by means of immunohistochemistry. The results showed that immunostaining for Fas, Fas ligand and active caspase-3 were not detected in morphologically normal primordial follicles in fresh ovarian tissue. After cryopreservation, Fas, Fas ligand and active caspase-3 immunostaining were present in morphologically normal primordial follicles. The study showed that cryopreservation of the human ovarian tissue induced the expression of Fas system in morphologically normal primordial follicles.

Ovarian sex cord-stromal tumors (SCST) are a rare subset of ovarian neoplasms originating from supportive tissues surrounding oocytes. Despite their rarity, prompt diagnosis and management are crucial due to their potential for diverse clinical presentations and the need to optimize patient outcomes. A 25-year-old female patient was initially diagnosed with pyelonephritis but later discovered to have a large right adnexal mass suspected to be a tubo-ovarian abscess.

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).

The distinctive characteristics of an individual's T cell receptor repertoire are crucial in recognizing and responding to a diverse array of antigens, contributing to immune specificity and adaptability. The repertoire, famously vast due to a series of cellular mechanisms, can be quantified using repertoire sequencing. In this study, we sampled the repertoire of 85 women: ovarian cancer patients (OC) and healthy donors (HD), generating a dataset of T cell clones and their abundance.

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.
