Our expert says:
IVF is a process whereby the ovary is hyper-stimulated to produce many follicles. The follicles will then need to be aspirated as this is usually done transvaginally. Each follicle has the potential to carry an oocyte. Once the oocyte has been retrieved from the ovary in a laboratory, sperm will then be added to the oocyte to allow for fertilization to take place. Within 2 to 4 days time an embryo will result and then the best quality embryos will then be inserted into the endometrial cavity to allow for implantation and hopefully a pregnancy. The difference between a long term and a short-term protocol is essentially how long one would down-regulate the ovaries to control the cycle. Preference for one or the other would generally depend on the clinician, however the success rates for both the protocols are the same.
