Our endocrinologists work in a multi-disciplinary team, including the service at Queen Charlotte’s that was started by Lord Winston to assess and treat couples with reproductive problems. Some of the fertility problems we treat include; endometriosis, polycystic ovary syndrome (PCOS), azospermia and impotence. We also see patients who need investigation of hirsuitism and patients with primary or secondary amenorrhea, including patients with prolactinomas.
