Summary

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).

Detailed description

This is a single-center, prospective observational cohort study conducted at the McGill University Health Centre Reproductive Centre. Women undergoing IVF with planned fresh or frozen blastocyst embryo transfer will be enrolled and categorized based on tattoo presence and characteristics. Tattoo information will be collected using a standardized questionnaire and direct measurement. Participants will be followed for pregnancy and obstetric outcomes through medical chart review. The primary outcome is ongoing pregnancy rate following embryo transfer. Secondary outcomes include clinical pregnancy, biochemical pregnancy, miscarriage, ectopic pregnancy, and live birth.
