We present a case of a 29-year-old lady who presented with subfertility. She had had a 2 years history of oligomenorrhoea with highly irregular menses. She had symptoms of depression and described tunnel vision. Clinically, she was euendocrine with no features of hormonal excess or deficiency. She was not hirsute. Visual field testing demonstrated a severe left superior temporal quadrantopia.Laboratory investigations demonstrated an oestriadol level rang...

Objectives: To examine the effect on weight change of diet/lifestyle advice to maintain/achieve a healthy weight in an unselected PCOS population.Methods: All overweight patients attending the Reproductive Endocrine clinic with PCOS are routinely given lifestyle advice for weight loss by their consultant, offered referral to see a dietician and, when clinically appropriate, prescribed orlistat. Clinical notes were reviewed for 50 consecutive patients wit...

Introduction: Hypothalamic amenorrhoea (HA) is a condition characterised by reduced GnRH pulsatility and is a common cause of anovulatory subfertility. Kisspeptin is an endogenous neuropeptide that regulates hypothalamic GnRH function. Hypothalamic kisspeptin expression is reduced, and kisspeptin receptor expression is increased, in a rodent model of HA. The kisspeptin analogue MVT-602 has a 3-4-fold longer half-life than native kisspeptin-54 (t1/2 0.5 h). We invest...

Introduction: Duodenal mucosal resurfacing (DMR) is a novel therapy for T2DM. It involves the hydrothermal ablation of up to 14 cm of the duodenal mucosa through a specially designed endoscopic catheter. The procedure is performed under general anaesthesia, patients are discharged the same day and it does not involve the implantation of a foreign body. Cohort studies have demonstrated that DMR induces meaningful hbA1c reductions of 0.9–1.4% by 3 months that are largely m...

Background: Polycystic Ovary Syndrome (PCOS) and Functional Hypothalamic Amenorrhoea (FHA) are the two commonest causes of menstrual disturbance in pre-menopausal women. In practice, differentiating these two common reproductive disorders can be challenging. A fundamental abnormality that underpins both conditions is altered gonadotrophin releasing hormone (GnRH) pulsatility, being increased in PCOS but reduced in FHA. Likewise, congenital (e.g. congenital hypogonadotropic hyp...
