Aim: The aim of this article is to review the evidence regarding human oocyte cryopreservation by slow freezing and vitrification and to provide evidence-based clinical and laboratory guidelines on the effectiveness and safety of these technologies.
Scope: These guidelines will address the following: Stage of oocyte maturity. Methods of cryopreservation/warming. Slow controlled cooling. Vitrification. Techniques used for insemination. Ovarian stimulation regimens. The guidelines do not cover recommendations for ovarian tissue freezing or in vitro oocyte maturation (IVM).
Outcome Measures: The following outcome measures were examined: cryosurvival, fertilisation rate, cleavage rate, clinical pregnancy rate and implantation rate, health of resulting children.

An increasing number of patients utilizing in vitro fertilization (IVF) and assisted reproductive technology (ART) are characterized as impaired or poor ovarian responders (PORs). Owing to its unclear molecular etiology, the management of patients with age-related ovarian characteristics remains a controversial and complex clinical concern. Therefore, it is important to identify and understand the etiological causes behind POR to develop more effective and efficient management strategies for these patients.

Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by periodic fever, serositis, and arthritis. In women, FMF attacks can sometimes be triggered by the menstrual cycle. Once diagnosed, prophylactic treatment with colchicine is generally recommended.

Introduction: Premature ovarian insufficiency (POI) is a condition characterized by ovarian dysfunction occurring before the age of 40, and its etiology is multifactorial, including genetic, immunological, infectious, environmental, and iatrogenic factors, with over half of the cases remaining unexplained. Whether the microbial communities and metabolites in follicular fluid, which is the direct microenvironment for oocyte survival, are related to POI has not been reported.
Methods: In this study, Follicular fluid samples of 26 patients with POI and 27 controls with a normal ovarian reserve were collected and analyzed using 16S rDNA sequencing and untargeted metabolomics.

Objective: To evaluate the efficacy of a microfluidic culture system supplemented with follicular fluid meiosis-activating sterol (FF-MAS) on the maturation of immature oocytes in patients with polycystic ovarian syndrome (PCOS).
Methods: A total of 438 germinal vesicle oocytes from 163 PCOS patients were included. Oocytes were divided into five groups: (1) cultured in static drops without FF-MAS, (2) cultured in static drops with FF-MAS, (3) cultured in a microfluidic device without FF-MAS, (4) cultured in a microfluidic device with FF-MAS for the first 2 h, and (5) cultured in a microfluidic device with FF-MAS for 24 h.

We assessed the safety and efficacy of rhFSH-CTP, a novel long-acting FSH agent, in controlled ovarian hyperstimulation for patients undergoing ART. A multi-center, open-label, randomized, positive-control, non-inferiority clinical trial was conducted. The study consisted of a phase III randomized design, with a 1:1 ratio favoring the rhFSH-CTP group over the control group.
