IVF is a process by which an egg is fertilised by sperm in the laboratory, outside the body: in vitro (“in glass”), in order to obtain fertilized embryos for transfer to the mother’s uterus.
The fertilisation of the ova can be carried out by means of the conventional IVF method or by Intracytoplasmic Sperm Injection (ICSI).
IVF using semen from the couple is recommended for:
- Couples for whom simple methods such as Intrauterine Insemination (IUI), have failed.
- Women with complete absence of or lesions on the fallopian tubes.
- Women suffering from advanced endometriosis with probable repercussions on the fallopian tubes and on oocyte quality.
- Situations in which there is a limited number of oocytes.
- Cases of severe male factor infertility.
IVF using semen from a donor is recommended for:
- Serious cases of male factor infertility with poor sperm quality.
- Previous failed fertilization using semen from the couple.
- Cases of poor quality embryos or repeated implantation failures, mainly due to male factor.
- Men who are carriers of a genetic disease that can not be studied in embryos.
- Women without a partner.
It is the most widespread method of Medical Assisted Reproduction in the world, with extremely high success rates and concrete scientific assurances that it is a safe medical procedure.
