Objective
LUTEAL PHASE DEFICIENCY
Conventionally, hCG is used as a ‘faux’ LH surge to bring final oocyte
maturation due to structural similarity with LH. Although GnRH agonists
induce a more physiological gonadotropin surge for follicular maturation,
they have been associated with luteal phase deficiency. Our aim was to
assess whether adding a gonadotropin-releasing hormone agonist (GnRHa) to
hCG trigger improves oocyte maturation and the number of high-grade embryos
in GnRH antagonist IVF cycles.
