A self-excited threshold autoregressive state-space model for menstrual cycles: forecasting menstruation and identifying ovarian phases based on basal body temperature [PDF]
Statistics in Medicine 38 (2019) 2157-2170, 2017 The menstrual cycle is composed of the follicular phase and subsequent luteal phase based on events occurring in the ovary. Basal body temperature (BBT) reflects this biphasic aspect of menstrual cycle and tends to be relatively low during the follicular phase.

PCONet: A Convolutional Neural Network Architecture to Detect Polycystic Ovary Syndrome (PCOS) from Ovarian Ultrasound Images [PDF]
arXiv, 2022 Polycystic Ovary Syndrome (PCOS) is an endrocrinological dysfunction prevalent among women of reproductive age. PCOS is a combination of syndromes caused by an excess of androgens - a group of sex hormones - in women. Syndromes including acne, alopecia, hirsutism, hyperandrogenaemia, oligo-ovulation, etc. are caused by PCOS. It is also a major cause of

Novel contraceptive targets to inhibit ovulation: the prostaglandin E2 pathway.
Human Reproduction Update, 2015 BACKGROUND Prostaglandin E2 (PGE2) is an essential intrafollicular regulator of ovulation. In contrast with the one-gene, one-protein concept for synthesis of peptide signaling molecules, production and metabolism of bioactive PGE2 requires controlled ...

Kisspeptin-neuron control of LH pulsatility and ovulation
Frontiers in Endocrinology, 2022 Feedback from oestradiol (E2) plays a critical role in the regulation of major events in the physiological menstrual cycle including the release of gonadotrophins to stimulate follicular growth, and the mid-cycle luteinising hormone (LH) surge that leads
