Background: Infertility affects 1 in 6 couples causing devastating psychological impact. In vitro fertilisation (IVF) treatment can aid couples to conceive, but personalisation of treatment is needed to optimise patient outcomes. Machine learning can aid in the analysis of large complex datasets such as those encountered during IVF treatment. One example is in determining the optimal follicle size on the day of trigger to maximise the number of oocytes collected. Both follicle...

Background: Due to practical limitations, the diagnosis of hypogonadism is predominantly based on a single measure of reproductive hormones, often with confirmation on a second occasion. Factors associated with reproductive hormone variation include: pulsatile secretion, diurnal rhythm, and food intake, which can affect the accuracy of diagnosis of reproductive disorders. There is limited data quantitatively estimating the variability of reproductive hormone levels over the da...

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...
