NCT07825584
Sperm Selection Strategies and Male-Factor Phenotypes in ICSI
This retrospective multicentre observational cohort study evaluates clinical and reproductive outcomes associated with different sperm-selection strategies used during intracytoplasmic sperm injection (ICSI), including conventional ICSI, hyaluronan-binding sperm selection (PICSI), and microfluidic sperm selection. The study uses routinely collected real-world clinical and laboratory data from fertility treatment cycles performed at multiple centres. Analyses will assess overall comparative effectiveness and whether treatment effects differ according to male-factor phenotypes, including sperm DNA fragmentation. Key outcomes include fertilization, embryo development, pregnancy establishment, pregnancy loss, and cumulative reproductive outcomes at the source-cycle level. The study is observational; treatment allocation was determined by routine clinical practice rather than by a study protocol.

The Impact of Having a Tattoo on Fertility Treatment Outcome
Tattoos are increasingly common among women of reproductive age, yet their potential systemic inflammatory effects and impact on fertility treatment outcomes are unknown. This prospective observational cohort study aims to evaluate whether the presence, size, duration, and ink characteristics of tattoos are associated with pregnancy outcomes following embryo transfer in women undergoing in vitro fertilization (IVF).
