Abstract

fetched live from OpenAlex

ObjectiveTo report a successful case of oocyte cryopreservation and subsequent in vitro fertilization (IVF) in a transgender male receiving continued testosterone gender-affirming hormone therapy, followed by reciprocal embryo transfer (ET).DesignA case report of a rare case of fertility preservation in a transgender man with concomitant use of testosterone therapy for 4 years before and during ovarian stimulation.SettingPrivate fertility clinic with university affiliation.Patient(s)A 26-year-old transgender man undergoing oocyte cryopreservation before gender-affirming surgery.Intervention(s)Fertility preservation using oocyte cryopreservation and IVF with reciprocal fresh ET into a cisfemale partner.Main Outcome Measure(s)Successful oocyte cryopreservation, oocyte thawing, and reciprocal IVF cycle.Result(s)Oocyte cryopreservation of 29 mature oocytes. Sixteen mature oocytes survived the thaw, and 12 were fertilized with intracytoplasmic sperm injection. A fresh ET of an advanced blastocyst resulted in a clinical pregnancy and live birth.Conclusion(s)Fertility preservation with oocyte cryopreservation or IVF with embryo cryopreservation is feasible for patients on continued long-term testosterone gender-affirming therapy. Future studies on egg quality and reproductive outcomes are required. Our case report demonstrates a promising outcome in this patient population.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
