About this image

Intracellular Sperm Injection is an IVF technique usually employed where the patient’s sperm count is very low, the sperm are deformed or their motility is poor. The oocyte (‘egg-to-be’) is held, by suction, against the end of a micropipette and a single, selected sperm drawn into an even finer pipette with a pointed end. This is then inserted into the oocyte and the sperm injected. This extremely delicate manoeuvre is carried out using an inverted microscope and micro-manipulator.
