The test-tube baby technique
IVF means fertilization outside the body in a test tube. Since the birth of Louise Brown, the first test-tube baby in 1978, IVF has resulted in about 5,000,000 babies worldwide (ICMART Global Report 2012). Pregnancy rates and live birth rates have improved over the past few years, leading to a steady increase in the number of IVF treatment cycles performed worldwide. For example in the USA, a total of 142,241 IVF cycles using own eggs and a total of 15,099 IVF cycles using donor eggs were performed in 2009 (SART report). The latest report from United Kingdom a total of 57,652 IVF and ICSI treatment cycles were performed, an increase of 5.9% on the number of cycles in 2009. Furthermore, in the United Kingdom almost two-thirds of the women treated with IVF aged 37 or younger and almast one in five women having IVF in the United Kingdom is 40 years or older. Most of the IVF treatments in the UK were privately funded (59.7%)

There are several groups to whom IVF treatment may be advised that include:
- Women with blocked, damaged Fallopian tubes or inoperable tubes or whose tubes have been removed after ectopic pregnancies.
- Women with endometriosis.
- Women with cervical mucus problems.
- Men with infertility problems.
- Men or women with immunological infertility problems.
- Couples with unexplained infertility.
A full cycle of IVF treatment, with or without intracytoplasmic sperm injection (ICSI), should comprise 1 episode of ovarian stimulation and the transfer of ny resultant fresh and frozen embryo(s)
- In women aged under 40 years who have not conceived after 2 years of regular unprotected intercourse or 12 cycles of artificial insemination (where 6 or more are by intrauterine insemination), offer 3 full cycles of IVF, with or without ICSI.If the woman reaches the age of 40 during treatment, complete the current full cycle but do not offer further full cycles
- In women aged between 40 and 42 years who have not conceived after 2 years of regular unprotected intercourse or 12 cycles of artificial insemination (where 6 or more are by intrauterine insemination), offer 1 full cycle of IVF, with or without ICSI, provided the following 3 criteria are fulfilled (1) they have never previously had IVF treatment (2) there is no evidence of low ovarian reserve and (3) there has been a discussion of the additional implications of IVF and pregnancy at this age.
- Where investigations show there is no chance of pregnancy with expectant management and where IVF is the only effective treatment, refer the woman directly to a specialist team for IVF treatment.
- In women aged under 40 years any previous full IVF cycle, whether self- or NHS-funded, should count towards the total of 3 full cycles that should be offered by the NHS. .
