Objectives: To analyze follicular fluid (FF) vitamin D in females doing Intracytoplasmic Sperm Injection (ICSI), to compare its level between Polycystic Ovary Syndrome (PCOS) and non-PCOS females, and to explore whether vitamin D correlates with oocytes number, percentage of oocyte maturity, fertilization rate and percentage of high quality embryos.
