AMSTERDAM, This randomized, controlled trial was conducted at a tertiary IVF center, Ho Chi Minh City, Vietnam. Between January 2023 and June 2023, 120 women were randomized. Eligible women were aged 18-37 years with polycystic ovarian syndrome (PCOS). After providing written informed consent, participants were randomized (1:1) to undergo CAPA-IVM with or without FSH-priming. Participants in the FSH-priming group received two days of recombinant FSH (rFSH) injections before oocyte pick-up; no rFSH was given in the non-FSH group. All retrieved cumulus oocyte complexes underwent biphasic in vitro maturation (CAPA-IVM). Matured oocytes underwent fertilization through ICSI procedure, and were cultured to blastocyst stage followed by vitrification. Participants underwent a single blastocyst transfer during a frozen replacement cycle. The primary endpoint was the number of matured oocytes.

The number of matured oocytes after CAPA-IVM did not differ significantly between the non-FSH and FSH groups (13 [9; 18] vs. 1
4 [7; 18]; absolute difference -1 [95% confidence interval -5, 4]). There were also no significant between-group differences in other oocyte and embryology outcomes, including the number of cumulus-oocyte complexes, number of fertilized oocytes, total number of blastocysts and good blastocysts, and total number of frozen embryos. The live birth rate was 38.3% in the non-FSH group and 31.7% in the FSH group, with no statistically significant difference. The miscarriage rate at
