Intracytoplasmic sperm injection (ICSI)
The intracytoplasmic sperm injection (ICSI) is indicated for cases of male infertility or IVF fertilisation failures. It makes the egg fertilisation possible with a single spermatozoa.
This technique is the solution for many cases of severe male factor infertility. It’s a therapeutic option which offers the best results in this type of patients. However, couples in individual reproduction treatments can also choose this technique if the embryologist and the gynaecologist advice so.
The intracytoplasmic sperm injection (ICSI) follows the same protocol as a conventional in vitro fertilisation. The only difference is the way in which the fertilisation is done once the eggs and sperm are collected in the laboratory. With this technique, it is necessary to know the maturation of the eggs collected, by means of their denudation, in order to carry out the ICSI.
The success of this technique depends to a large extent on the women’s age. The pregnancy rate per cycle is between a 40% and a 65%, although in patients under the age of 32, this percentage can be of 70% in three cycles. Each case is examined individually by specialists at the HLA Vistahermosa Reproduction Unit to seek the higher percentage of pregnancy success
