In 2014 a 36-year-old healthy female-to-male transgender patient attended the London Women's Clinic to consider oocyte and embryo freezing before sex reassignment surgery. The patient began IVF treatment in 2015; from two cycles, nine metaphase II oocytes and five blastocysts were frozen. Three years later the patient returned with his partner, a 39-year-old healthy transgender male-to-female individual, ready to start a family with surrogacy treatment.

Introduction: This study investigated the efficacy of a digital health solution utilizing smartphone images of colorimetric test-strips for home-based salivary uric acid (sUA) measurement to predict pre-eclampsia (PE), pregnancy-induced hypertension (PIH), and intrauterine growth restriction (IUGR).

Methods: 495 pregnant women were included prospectively at Zealand University Hospital, Denmark. They performed weekly self-tests from mid-pregnancy until delivery and referred these for analysis by a smartphone-app.

Research Question: What number of retrieved oocytes is associated with the optimum chance of achieving a live birth for women undergoing ovarian stimulation with individualized follitropin delta?

Design: An individual patient data meta-analysis was performed on 1772 patients from five randomized controlled trials using individualized follitropin delta for ovarian stimulation with fixed daily dosing based on serum anti-Müllerian hormone (AMH) level and body weight. Live birth rate (LBR) and ovarian hyperstimulation syndrome (OHSS) were evaluated in relation to the number of oocytes retrieved. Predicted LBR was obtained using a logistic regression analysis with fractional polynomials.

Article Synopsis
  • - Aromatase inhibitors, especially letrozole (LZ), are now recognized as effective first-line treatments for inducing ovulation and enhancing intrauterine insemination outcomes.
  • - LZ is gaining traction as an adjunct to gonadotropin therapy in IVF, particularly beneficial for women with estrogen-sensitive cancers, by lowering estrogen levels.
  • - Recent studies suggest that LZ can aid poor responders in IVF, mitigate ovarian hyperstimulation syndrome, and improve the luteal phase, while also being useful for preparing the endometrium in frozen-thawed embryo transfers.
