Amenorrhea; Infertility; Polycystic Ovary Syndrome

Research group(s)

Research interests

My main research focuses are polycystic ovary syndrome, infertility, amenorrhoea, thyroid disorders and their association with female health, recurrent miscarriage, and reproductive surgery. The research is designed to elucidate clinical/ therapeutical issues and to shed light on pathophysiologic mechanisms.

In addition, I have the honor to be a part of the working group of placental abnormalities and maternal ultrasound in the field of feto-maternal medicine.

Techniques, methods & infrastructure

Clinical trials (prospective randomized trials, prospective cohort studies), meta-analyses.
