In-vitro fertilisation (IVF)
IVF is recommended for:
- Blocked or damaged fallopian tubes
- Mild or moderate sperm problems
- Unexplained infertility
- Severe endometriosis
- Part of a donor-egg treatment cycle
- Part of an ICSI (Intra Cytoplasmic Sperm Injection) cycle
- As part of sperm recovery (PESA/TESA/MESA cycle)
There are several aims of treatment including:
- An increase in the number of eggs produced in a cycle by the administration of drugs called gonadotrophins (i.e.Metrodin, Puregon or Menopur).
- The preparation and harvesting of the best quality sperm for insemination.
- Fertilisation of the eggs in a laboratory by mixing sperm and eggs in a dish (i.e. bringing them very close together) and therefore by-passing the fallopian tubes where fertilisation would normally take place.
- The replacement of 1,2 or 3 embryos (the first stages of life) in the womb in the hope that one will implant itself in the lining of the womb (endometrium) and begin a pregnancy.
- Freezing any spare embryos if possible so that they can be used in later treatment cycles if needed. See section on Embryo Freezing for more information.
