Microinjection is science’s elegant answer to severe male infertility
Intracytoplasmic sperm microinjection (ICSI)
In classical in vitro fertilization (IVF), once eggs have been retrieved, they are usually fertilized by placing them in a test tube with 50,000 to 100,000 sperm. Fertilization, therefore, occurs naturally in an incubator. However, in cases of severe male infertility (less than a million sperm per millilitre), the fertilization process often requires assistance.
Microinjection of sperm (intracytoplasmic sperm injection, ICSI) has been developed to solve this problem. It involves injecting a single sperm into each egg using a small glass needle. The procedure takes place in the laboratory, under microscope. Fertilization rates are generally very good. This means that today many couples can have a biological child, whereas before they had to resort to insemination with donor sperm or adoption.

Over time, the indication to proceed to a microinjection ( ICSI) was extended to several other causes of infertility.
