Fertility and age limit


Infertility is defined as the failure to conceive after one year of having regular unprotected intercourse. For couples who have already managed to conceive in the past infertility is defined as failure to conceive after 6 months of having regular unprotected intercourse. The World Health Organisation estimates that 1 in 6 couples are affected by subfertility; some believe this number to be higher.

Infertility can result from male, female, or combined factors and in approximately 15% of the cases infertility remains unexplained. Male causes of infertility include sexual disfunction, sperm abnormalities, azoospermia (no sperm in the ejaculate) or the presence of anti-sperm antibodies. Female infertility factors include lack of ovulation due to PCOS or other causes, endometriosis, tubal blockage and polycystic ovaries. Genetic disorders and chromosome abnormalities can also result in infertility. A woman's age is the most significant factor affecting the chances of success.

In the past 30 years, over 3 million babies have been born thanks to Assisted Reproductive Technology (ART). In Europe, ART is responsible for over 2% of births every year.

Age limit

As a private clinic, our patients’ treatment is not limited by their age as it is in a NHS setting.  We support a higher age threshold for our patients and offer alternative methods of treatment for those who are approaching or have reached those thresholds.

We offer treatment for women using their own eggs from 18 years of age up to their 46th birthday, that’s an additional six years over most NHS trusts.  For women above this threshold, we have egg donation and surrogacy options. Regardless of your age at the time you start treatment with us, we will be honest and transparent about your likelihood of success. 

We believe it is your right to choose your options and encourage all of our patients to make fully informed decisions about what route of treatment they would like to pursue.

There are no restrictions on the age of men who can have treatment at City Fertility.
