What should you know about multiple ovulation embryo transfer technology?

In fertility treatment, medicines can stimulate the ovaries so several follicles develop during a treatment cycle. The eggs may then be collected and fertilised in the laboratory. An embryo transfer places a selected embryo through the cervix into the uterus using a fine catheter. The phrase multiple ovulation describes the ovarian stimulation stage; it does not mean that several embryos must be transferred. The clinic decides whether a fresh or frozen transfer is suitable, based on embryo development, the uterine lining and your health.

Follow the clinic’s medication and scan schedule closely, because doses may change as the ovaries respond. Ask how eggs and embryos will be handled, whether transfer will occur in the same cycle, and what alternatives exist if the lining or hormone levels are not suitable. Luteal support may include [Micronised Progesterone](/materials/micronised-progesterone/). The wider treatment pathway is explained in [IVF](/treatments/fertility-and-assisted-reproduction/ivf/). Avoid changing prescribed medicines without speaking with the fertility team.

Contact the fertility clinic urgently for severe abdominal swelling or pain, repeated vomiting, shortness of breath, faintness, reduced urination, heavy bleeding or a fever. These symptoms can indicate a complication of ovarian stimulation or another problem requiring assessment. Mild cramps or light spotting can occur after procedures, but report them if they become stronger or persistent.

Ask how your ovaries are responding, how many embryos may be considered for transfer, and whether the plan is fresh or frozen. Discuss the purpose and timing of progesterone, activity advice after transfer, pregnancy testing, and what the clinic will do if the cycle needs to be paused.
