What is intracytoplasmic sperm injection (ICSI)?
Intracytoplasmic sperm injection (ICSI) is a form of IVF treatment that involves injecting a single sperm into each egg using very fine micromanipulation equipment.
As the human egg is one-tenth of a millimetre in diameter and the sperm 100 times smaller this is a very delicate procedure performed by highly skilled embryologists using a sophisticated microscope.
ICSI has not been shown to increase fertilisation rates in situations where the sperm assessment is normal. Normal fertilisation rates with IVF or ICSI are approximately 50-60%. That is, for every 10 mature eggs obtained and combined with the sperm either with IVF or ICSI, approximately five to six will fertilise normally.
If there is evidence of poor outcomes with previous ICSI treatment, your Nairobi IVF fertility specialist may recommend you undergo Intracytoplasmic morphologically selected sperm injection (IMSI) to improve your chances of pregnancy success.
