Mr Hany Lashen

Personal profile

Mr Hany Lashen joined the University of Sheffield in 2000 as a Clinical Senior Lecturer in Obstetrics and Gynaecology and also worked as a Consultant in Gynaecology and Reproductive Medicine. Since then, as well as providing an excellent clinical service, he has had a varied research interest in several aspects of reproduction including reproductive endocrinology, reproductive potential, psychological impact of reproductive failure and reproductive surgery (including endometriosis, pelvic pain, fibroids and abnormal period management).

Mr Lashen has a widespread research programme with an overarching theme of the interaction between genetics, development and the environment on ovarian development, ovarian reserve, reproduction and the impact of energy balance especially overweight and underweight on reproductive performance (including fetal development) in women.

Most recently, he has formed a strong international group of eminent academics from the UK and Finland to study the relationship between hyperandrogenism as a function of the interaction between development and the genome and its impact on cardiovascular risk in teenage girls. This programme is being funded through a grant from Welcome Trust.

He has had several research projects with regards to ovarian response to simulation and protocol development in relation to the use of GnRH agonists and antagonists and poor responders, impact of anthropometry on ovarian response to controlled simulation,  endocrinological metabolic, and the social and developmental aspects of polycystic ovary syndrome and hirsutism.
