Dr Alessandra Parrella is National Laboratory Director and an embryologist specialising in assisted reproduction at the IVF-Life Alicante clinic, with extensive experience in in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI).Her work focuses on optimising laboratory protocols, gamete selection, and the assessment of oocyte and embryo quality, helping to improve reproductive outcomes for couples experiencing difficulties conceiving. In addition, she combines her clinical practice with research in reproductive biology, focusing on sperm DNA integrity, oocyte maturation, and embryonic development.

Research Interests
Her research focuses on assisted reproduction and ICSI techniques, with particular emphasis on sperm selection and chromatin integrity analysis. She also investigates oocyte maturation and its impact on fertilisation and embryo development, the application of microfluidics in gamete selection, sperm DNA fragmentation and its relationship with reproductive outcomes, as well as the development of treatment algorithms for couples affected by male infertility.
