Laura Melado Vidales: New Insights on LH Levels in Frozen Embryo Transfer Cycles

Laura Melado Vidales, Medical Director ART Fertility Clinics Abu Dhabi at ART Fertility Clinics, shared a post on LinkedIn about a paper published in RBMO:

“Our latest research explores the role of systemic LH concentration in programmed single euploid frozen embryo transfer (seFET) cycles.

758 programmed seFET cycles were assessed to determine whether LH levels were associated with pregnancy and live birth outcomes.

Key finding: LH concentration before starting vaginal progesterone does not influence live birth rates in programmed seFET cycles. Instead, factors such as embryo quality, day of biopsy, and BMI showed stronger associations with outcomes.

These results help refine clinical practice by reinforcing that routine LH monitoring may not be necessary in programmed FET cycles prepared with oral oestradiol and vaginal progesterone.
