However, if tests show IVF is the only treatment likely to help them get pregnant, women should be referred for IVF straight away. This policy is often modified by local Clinical Commissioning Groups, in a fairly blatant breach of the NHS Constitution for England which provides that patients have the right to drugs and treatments that have been recommended by NICE for use in the NHS. For example, the Cheshire, Merseyside and West Lancashire Clinical Commissioning Group insists on additional conditions:
The person undergoing treatment must have commenced treatment before her 40th birthday;
The person undergoing treatment must have a BMI of between 19 and 29;
Neither partner must have any living children, from either the current or previous relationships. This includes adopted as well as biological children; and,
Sub-fertility must not be the direct result of a sterilisation procedure in either partner (this does not include conditions where sterilisation occurs as a result of another medical problem). Couples who have undertaken a reversal of their sterilisation procedure are not eligible for treatment. Canada
Some treatments are covered by OHIP (public health insurance) in Ontario and others are not. Women with bilaterally blocked fallopian tubes and are under the age of 40 have treatment covered but are still required to pay test fees (around CA$3,000–4,000). Coverage varies in other provinces. Most other patients are required to pay for treatments themselves. Israel
Israels national health insurance, which is mandatory for all Israeli citizens, covers nearly all fertility treatments.
According to CDC, "they do not include treatments in which only sperm are handled (i.e., intrauterine—or artificial—insemination) or procedures in which a woman takes medicine only to stimulate egg production without the intention of having eggs retrieved. "In Europe, ART also excludes artificial insemination and includes only procedures where oocytes are handled.The WHO, or World Health Organization, also defines ART this way. Ovulation induction
Ovulation induction is usually used in the sense of stimulation of the development of ovarian follicles by fertility medication to reverse anovulation or oligoovulation. These medications are given by injection for 8 to 14 days. A health care provider closely monitors the development of the eggs using transvaginal ultrasound and blood tests to assess follicle growth and estrogen production by the ovaries. When follicles have reached an adequate size and the eggs are mature enough, an injection of the hormone hCG initiates the ovulation process. Egg retrieval should occur from 34 to 36 hours after the hCG injection. In vitro fertilization
In vitro fertilization is the technique of letting fertilization of the male and female gametes (sperm and egg) occur outside the female body. Techniques usually used in in vitro fertilization include:

Transvaginal ovum retrieval (OVR) is the process whereby a small needle is inserted through the back of the vagina and guided via ultrasound into the ovarian follicles to collect the fluid that contains the eggs.
