55 results about "Corpus luteum" patented technology

The corpus luteum (Latin for "yellow body"; plural corpora lutea) is a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone and moderate levels of estradiol and inhibin A. It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation.

Wearable sweat sensor for ovulatory hormone monitoring

Tracking ovulatory hormone levels is key to detecting fertility windows and providing actionable information for facilitating or preventing conception, as well as assessing and managing infertility and other conditions associated with hormone imbalances. Conventional fertility methods suffer drawbacks associated with invasive sampling, inadequate prediction accuracies, or repetitive user intervention. To overcome these and other limitations, the present Applicants developed a wearable device for contemporaneous monitoring of estradiol, progesterone, and luteinizing hormone and physiological biomarkers (temperature, pH). Flexible field-effect transistors functionalized with biomarker-specific aptamers enabled sensitive and selective determination of the three principal ovulatory hormones across physiological ranges in artificial human sweat. By including an on-demand iontophoretic sweat sampling feature, the present Applicants established an integrated wearable platform for high-accuracy, minimally invasive, rapid, and personalized ovulatory status monitoring.
