In natural cycle IVF is considered to be a patient friendly treatment as it is conducted without the use of medications to stimulate the ovaries to produce multiple eggs. The first successful IVF program in the natural cycle, which ended with the birth full-term healthy baby- girl was performed in 1978.
IVF in natural cycle is a program during wich no medication is used for ovaries stimulating to produce multiple eggs.
At the same time, the growth of follicles is monitored (there can be one or two in the natural cycle of the woman), and when they are matured to the desired size (up to 18 mm), eggs are retrieved from follicles, then fertilized in the lab and then the best embryos are transferred back into the woman’s uterus.
Amongst disadvantages of IVF in natural cycle we should name a small number of oocytes, which can be obtained for fertilization (as a rule, only one). From one oocyte, we can only get one embryo, and we have no choice for transfer.
The nature is pretty strict while choosing an embryo for a safe pregnancy. Up to 70% of the material is eliminated; therefore, the effectiveness of IVF in natural cycle is not too high, even in spite of the efforts and high quality of embryological service and professionalism of embryologists. Moreover sometimes in natural cycle, we may not receive an oocyte at all (especially in the late reproductive age), or it will be of poor quality and not suitable for fertilization.
The success of IVF in natural cycle mainly depends on the quality of embryology and clinic open hours (24/7/365) which allows to retrieve oocytes any day of a week. All these we are glad to provide in GMS IVF: «The house of family planning and reproduction».

Long time ago, when I was 18, I got pregnant but I didn’t know about it. Those were days when I was a carefree girl who didn’t really pay attention to menstrual cycles; if my periods were delayed, I didn’t think much about it. Now it’s hard to believe I was like that, but it’s true.More
I sit back and watch my little 6-month-old wonder, peacefully burbling in the cradle. I have an opportunity to look back at every memory from the beginning.More
