Success rate with infertility treatments and IVF in general depend on a number of factors. Even though age is one of the main categories by which IVF clinics publish their success rates, there are numerous factors other than the patients' age that will determine how likely they are to succeed with treatment. Egg quality, cervical factors, uterine factors, infectious diseases, sperm related issues, immune system problems are other major factors that determine how likely you are to achieve success. Your unique success chance can be very different from the age group that you are categorized in, depending on your own fertility assessment parameters.
It should be known that even though each patient is different from the other and no single prescription will fit all, there are certain things that we can all do in order to boost our chances of success with IVF treatment. Please see our "Tips for IVF Success" section for things you can do to improve your success chances with treatment. At North Cyprus IVF Center, we make sure each one of our patients is thoroughly assessed for fertility parameters so that we can provide each patient with a unique success chance before treatment is initiated. This is the main reason why success rates with IVF treatments at North Cyprus IVF Centre are substantially higher than the rest of the clinics in the area as well as majority of other clinics in the world!
Below, you will see success rates with IVF treatments in years 2012, 2013 and 2014. Please keep in mind that success rates provided below do not include single embryo transfers. Only cycles with 2 or 3 embryos transferred are reflected in our success rates. With single embryo transfer, chance of success will be significantly lower compared to 2 or 3 embryos transferred. Please keep in mind that our success statistics are calculated based on the number of cases of the past year. It has come to our attention that some of the smaller clinics are publishing success rates that are not reflective of their cases in order to attract patients, please do not honor these false statistics and only trust clinics that are fully accredited and regulated by a governing body.
Age of the female patient is one of the main factors which affect IVF success. The quality of sperm and sperm parameters are also important factors in achieving embryo fertilization. However, sperm production (spermatogenesis) is an ongoing biological process where mature sperm cells (spermatozoa) are continuously being produced by germ cells through the meiotic and mitotic activity. Egg production (oogenesis), on the other hand, is not a process where a female can produce more egg cells. Once a woman is born, she is born with a finite set of eggs in her ovarian reserves and the number of these egg cells decline via each menstrual cycle after puberty. Oogenesis, therefore, refers only to oocyte maturation after a female has been born. Given that a woman is born with a limited set of eggs, and she loses these eggs via each menstrual period, the older she gets, the lower the number of eggs she has in her reserves. Furthermore, just like any other cell in our body, egg cells (oocytes) also age with time, and become more prone to genetic abnormalities. These are the main reasons why women after a certain age have a difficult time conceiving or maintaining a pregnancy.

The figure to the right indicates the number of eggs in ovarian reserves in relation to age. 10^6, which corresponds to one million eggs refers to approximately how many primordial follicles (cysts containing immature eggs) a woman has at the time of birth. This number remains stable until puberty. Once a woman reaches puberty and starts ovulating, the number of follicles in ovarian reserves starts to decline. At about age 40, the reserves have fallen to a level of ten thousand primordial follicles, whereas this number is about slightly less than a million for someone who is 20.
