A fertile couple has a 17% chance of pregnancy in an unprotected sexual encounter. The chance of getting pregnant increases significantly with the help of fertility techniques. The figures you see here are from positive beta pregnancy test rates, that is, they refer to pregnancies confirmed by blood test and that may have terminated before being checked with an ultrasound scan. These figures should be treated with caution as they are dependent on various factors, mainly the woman’s age.
With their own eggs, it is important to realise that women are at their most fertile between the ages of 20 and 25 and from that time onwards their fertility starts to diminish slightly. From the age of 35 there is a marked decrease in fertility. The most significant drop in fertility is seen from the age of 38-40, meaning that the chance of a successful outcome is also lower. At the EUGIN Clinic we can help you with this treatment provided you are under the age of 43, although in some cases we can still assist older women, with the approval of the medical team.
In the case of IVF with donor eggs, the woman’s age is not an issue, as the donor will always be under 35. At the EUGIN Clinic we can help you with this treatment provided you are under the age of 50.
The success rate for artificial insemination – both AIH and AID are, in some cases, accumulative, peaking at between 3 and 6 attempts. The success of this treatment depends on a number of factors. For the woman, the greatest consideration is age (the older she is the less chance she has of getting pregnant) plus any ovarian disease or abnormalities, and genetic factors. For the man, it depends on the number and agility of his sperm. All these factors can have an impact on the outcome of treatment, so these figures should be taken as being merely informative and not as a guarantee of individual success.
In Artificial Insemination with donor sperm, the sample is obtained from a donor who has undergone a full medical check, so the quality of the sperm is assured. This means that there is, in theory, a greater chance of success than with the partner’s sperm (although until it is analysed we cannot be sure). Artificial insemination with donor sperm is normally suitable for couples where the man has a severe problem, or for single women, or for female couples who are not necessarily infertile. Because of this, results are considerably better in these cases than in the case of a couple with a history of infertility who undergo artificial insemination with the partner’s semen.
