For women aged 37–39 years: In the first and second full IVF cycles use single embryo transfer if there are one (1) or more top-quality embryos. Consider double embryo transfer if there are no top-quality embryos. For women aged 40–42 years consider double embryo transfer. For women undergoing IVF treatment with donor eggs, use an embryo transfer strategy that is based on the age of the donor. No more than two (2) embryos should be transferred during any one (1) cycle of IVF treatment. Where a top-quality blastocyst is available, use single embryo transfer. When considering double embryo transfer, advise people of the risks of multiple pregnancy associated with this strategy. Offer cryopreservation to store any remaining good-quality embryos after embryo transfer. Advise women who have regular ovulatory cycles that the likelihood of a live birth after replacement of frozen–thawed embryos is similar for embryos replaced during natural cycles and hormone-supplemented cycles. Luteal phase support after IVF Offer women progesterone for luteal phase support after IVF treatment. Do not routinely offer women human chorionic gonadotrophin for luteal phase support after IVF treatment because of the increased likelihood of ovarian hyperstimulation syndrome. Inform women undergoing IVF treatment that the evidence does not support continuing any form of treatment for luteal phase support beyond 8 weeks' gestation. Gamete intrafallopian transfer and zygote intrafallopian transfer There is insufficient evidence to recommend the use of gamete intrafallopian transfer or zygote intrafallopian transfer in preference to IVF in couples with unexplained fertility problems or male factor fertility problems. sperm injection Indications for intracytoplasmic injection The recognised indications for treatment by ICSI include: severe deficits in semen obstructive azoospermia non-obstructive azoospermia.
