There are four basic steps in an a typical IVF cycle. The first step will be the ovarian stimulation leading to egg collection. Then insemination and finally the formed embryo is transferred in the uterus of the female partner. In an unstimulated cycle, a single follicle that contains a single egg os developed to maturity.
My IVF cycle comprised of a set of medical steps such as egg and sperm retrieval from the couple, formation of embryo in the IVF lab, and transfer of embryo to uterus. The doctor can modify the timings of the steps depending on the complications of the case of the couple.
