IVF fertilization is beneficial in cases of low sperm count or limited motility, since sperm cells come into contact with the eggs inside a culture dish, meaning less sperm is required for fertilization. In contrast to IVF, a single sperm is injected into a single egg (see schematic drawing and pictures of organs) through a micro-injection, referred to as ICSI. This technique is beneficial in cases of poor sperm quality or with individual sperms extracted through testicular puncture.
As a last alternative for couples who have not had success with fertilization using the male partner’s sperm, despite ICSI, a heterological insemination (using donor sperm) can be offered. If the fallopian tubes of the woman are not obstructed, donor sperm will be injected into the uterus, providing the sperm has been examined according to the rules established by the Ministry of Health.

Indication
Intracytoplasmic sperm injection (ICSI) will be indicated, if an evaluation shows poor sperm as the cause of infertility. Natural fertilization is then not possible, due to low sperm count, limited motility, and/or increased number of misshapen sperm. In this case, a micro-injection is necessary to support fertilization.
Chances for success
The chance for successful pregnancy with the IVF treatment is 30-40% per IVF cycle, depending on the age of the couple, hormone levels, disease (Diabetes mellitus, hypertension, etc.) and lifestyle (excess weight, stress, alcohol and nicotine use, etc.)
