The accuracy and reproducibility of the endometrial receptivity array is superior to histology as a diagnostic method for endometrial receptivity
2013
Objective To compare the accuracy and reproducibility of the endometrial receptivity array (ERA) versus standard histologic methods. Design A comparative prospective study (May 2008–May 2012). Setting University-affiliated infertility clinic. Patient(s) Eighty-six healthy oocyte donors, regularly cycling, aged 20–34 years with a body mass index (BMI) of 19–25 kg/m 2 . Intervention(s) Endometrial biopsies were collected throughout the menstrual cycle. For the accuracy study, 79 samples were grouped into two cohorts: the training set (n = 79) for ERA machine-learning training and dating, and a dating subset (n = 49) for comparison between histologic and ERA dating. For the reproducibility stu…
Characteristics of urinary luteinizing hormone (LH) during the induction of LH surges of different magnitude in blood
1995
Urinary luteinizing hormone (LH) testing has been proposed as a reliable method for the prediction of ovulation but its accuracy has been challenged by some studies. To check how accurately the oscillations of urinary LH reflected the plasma changes, surges of LH of different magnitude and duration were artificially induced in plasma and the hormone was measured simultaneously in urine. Post-menopausal women (n = 16) were stimulated during 1 week with a combination of transdermal oestradiol (400 micrograms) and i.m. progesterone (25 mg on day 4, 50 mg on day 5) to obtain an LH discharge comparable with the pre-ovulatory LH peak. A short and moderate peak of LH was induced by the i.v. inject…
