Filter by:This exploratory study investigates fasting as a potential supportive therapy in infertility treatment for women suffering from infertility
This study was planned to assess the initial and endogenous FSH, LH and steroid responses to incremental CC doses in successive ovulation induction cycles to treat anovulation in patients with unexplained infertility.
This mobile application measures the level of certain hormones in the urine of a woman and is used to help pinpoint when the woman is/was most likely to get pregnant during her menstrual cycle.
The Ovulation Double Check test is a Class I, 510K exempt medical device. It is manufactured and packaged in an FDA-registered and cGMP compliant facility. This device measures the level of Pregnanediol (PdG), the major urine metabolite of progesterone, in the urine of women. PdG has been shown to increase significantly after ovulation has occurred. This test will be used in a home setting as a point-of-care device, providing couples additional information about menstrual cycling and possible fertile periods. The investigators have successfully developed prototype devices that can accurately measure PdG in urine. Now the investigators need to supply these prototype devices to end users to verify the assay is working correctly and determine if the device was designed properly in order for home users to 1) use the test properly, 2) read the test results properly, and 3) interpret the results correctly.
Rationale: There is some information suggesting that a progesterone-induced withdrawal bleeding before the start of ovulation induction in women suffering from oligo- or amenorrhea reduces pregnancy and live birth rate. Objective: To evaluate the effects of withholding progesterone-induced endometrial withdrawal bleeding before ovulation induction on the time to pregnancy and the ongoing pregnancy rate. Study design: Prospective multicenter randomized controlled feasibility study Study population: Women with oligomenorrhea or amenorrhea according to WHO classification category 2 Intervention: Patients will be randomized to receive one of the following two treatments: Stair step group: blind start ovulation induction (no progesterone induced withdrawal bleeding and stair step protocol in case of treatment failure. Control: standard care; a progesterone induced withdrawal bleeding in case of no spontaneous menses before starting an ovulation induction cycle and in between anovulatory cycles. Main study parameters/endpoints: The primary endpoints are the time to pregnancy and ongoing pregnancy rate within a treatment horizon of 3 cycles. Secondary endpoints include time to ovulation, endometrial thickness, multiple pregnancy and the incidence of treatment failure. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The number of site visits or physical examinations will not differ from accepted clinical practice.
The purpose of the study is to establish that sustained estrogen levels are the driving force for the LH surge, and are thereby necessary for ovulation to occur. We predict that by reducing levels of circulating estrogen, letrozole, an aromatase inhibitor, will inhibit ovulation from occurring.
