Fresh embryo transfer
In the GnRH agonist group 372 cases
(77%) completed fresh embryo transfer, resulting into
218 clinical pregnancies and 197
live birth. The clinical pregnancy rate, ongoing pregnancy, and live
birth per transfer were 58.6%, 54.0%, 53.0% respectively. Seventeen
(4.6%) and four (1.1%) women miscarried <12 weeks and
>12 weeks of gestation respectively. Fresh transfer was
canceled in 114 women due to elevated serum progesterone level on the
trigger day, risk of OHSS, suboptimal endometrial thickness or having no
transferable embryos. In the PPOS, no fresh transfer was carried out.
