In the beginning IVF attempts were made by collecting eggs during the natural menstrual cycles of the woman who wanted to have a baby. This is known as natural cycle IVF, which does not involve any ovarian stimulation. However, this natural cycle was replaced by ovarian stimulation procedures, as the latter resulted in higher success rates. Few infertility clinics still offer IVF procedures that are limited to the natural cycles or un-stimulated cycles.
Ovarian Stimulation-The Benefit
The stimulated process allows a larger number of embryos to be transferred and increases the pregnancy rate; therefore, ovarian stimulation is the preferred method for ICSI in IVF procedures. Now, we are seeing a revival of IVF in natural cycles. Many couples are better-informed about the risks of multiple babies and opt for a single healthy baby. If you want only one embryo to be transferred, there is no need to go through ovarian stimulation procedures. Of course, the chances of success may dip, but you have the option to go through multiple IVF cycles.

About Natural Cycle ICSI
A natural cycle ICSI consists of retrieving the eggs from the female partner without any stimulation. It involves retrieval of only one egg per cycle and the method is a simple and natural one that is patient friendly. Women who are below the age of 35 years can easily opt for a natural cycle IVF, whereas those above 35 prefer to opt for the transfer of multiple embryos using ovarian stimulation. Here are some facts:
- In a completely natural or an un-stimulated cycle, the risks of multiple pregnancy and hyperstimulation problems are completely eliminated
- Though the success rate may be less, you might actually benefit from the natural cycle ICSI treatment
- In many clinics, a certain percentage of couples prefer to go through the IVF procedure without making use of any fertility medications, apart from the hCG shot, which is actually used for triggering the ovulation

Natural Cycle ICSI- The Benefit
The advantages of a natural cycle procedure are that the embryo produced can be of a better quality due to the retrieval of a single egg. It can also be beneficial in implantation. If you are an older woman or a poor responder to stimulants, clinics like www.drmalpani.com also offer this option. If you have the problem of a poor quality embryo after stimulated cycles or if you are not able to take stimulation or fertility medications, you could try out a natural cycle. In case of a natural cycle, there is only one embryo, so it is recommended that the embryo be transferred on day 3 in a natural cycle IVF.
Though the chances of success in a stimulated ovarian IVF procedure are higher when compared to a natural cycle ICSI, some couples prefer to go in for an un-stimulated procedure for various reasons.
