Intracytoplasmic sperm injection and Embyro Transfer (ICSI-TE) consists in introducing only one spermatozoon in an ovum, to obtain embryo, to then select and transfer to the patient’s uterus. This technique does not require any additional process for the patient than IVF-ET.
It is prescribed in cases of male infertility with very low sperm counts which do not manage to fertilise the oocyte using conventional IVF techniques. The latest advances even allow the injection of sperm taken directly from the testicles of men who do not expel sperm during ejaculation. (Azoospermia)
