IVF is a four-stage process which includes ovarian stimulation, monitoring, and ovulation triggering, egg retrieval or ovum pick-up (OPU), fertilisation, and embryo transfer.
In an IVF cycle, eggs and sperm are collected and placed together in a dish to fertilise. The embryos produced from a successful fertilisation will be transferred into woman’s uterus. Potential surplus embryos can be kept frozen for future use.
ICSI is a procedure where a single sperm is injected directly into each egg. ICSI is often used if the male partner has a very low sperm count, low motility or poor sperm quality. Once fertilisation occurs, embryo transfer and freezing follows, similar to IVF.
