Scheduling cycles with gonadotropin-releasing hormone antagonist protocol in in vitro fertilization: Is there a scope in batch in vitro fertilization?

Abstract

In India, a practice of "Batch in vitro fertilization (IVF)" has evolved in many infertility centers in an effort to align infertility management with logistics. A "Batch IVF" is an approach where the menstrual cycles of multiple women are programmed, such that they can undergo all the processes; from stimulation until embryo transfer about the same time. In "Batch IVF", the day for initiating stimulation is calculated retrospectively from the day the visiting embryologist is available at the clinic (day of ovum pick-up). Aligning the cycles of multiple women with steroids followed by down regulation with long gonadotropin-releasing hormone agonist (GnRH-A) is one of the currently employed methods for batching. There is sufficient evidence on scheduling cycles with steroids in GnRH-An protocol without compromising on the outcome. The objective of this paper is to provide evidence-based clinical concept on scheduling cycles in "Batch IVF" setup with GnRH-An protocol through literature review.
