What is Natural Cycle In Vitro Fertilization?

For some women, who don’t react well or simply don’t want ovarian stimulation, natural cycle in vitro fertilization may be a good option to become pregnant.


What is Natural Cycle In Vitro Fertilization (IVF)?

In this assisted fertilization technique the extraction of quality oocytes is achieved without the need for hormonal stimulation.

During approximately 15 days, the natural ovulation cycle of the future biological mother is monitored through testing and ultrasound scans.

Follicular and endometrial growth is measured at the clinic in the span of 4 to 5 visits. This testing allows us to determine the ideal time to obtain the egg naturally, without medical stimulation and then the extraction is carried out using the usual IVF techniques.

That is why we say that fertilization is done in the Natural Ovulation Cycle.

The aim of natural cycle in vitro stimulation is to obtain a few high-quality oocytes.


Who is it for?

This technique can be applied to any couple or woman who does not want to undergo ovarian stimulation prior to the extraction of the eggs.

You can also take advantage of it if you have already undergone other assisted fertilization processes without successful multi-follicular growth. Meaning that after hormonal stimulation you have not produced enough follicles to continue the insemination process.


What are the advantages of Natural Cycle IVF?

Natural Selection:

During the process, the best possible egg is chosen, giving priority to quality before quantity.

No risk:

There is no hyperstimulation and no possibility of multiple pregnancies.

No hormones:

Since it does not involve having hormone treatments the side effects are minimal.

Without anaesthesia:

The egg retrieval is very quick, it only takes a couple of minutes and therefore it doesn’t need to be performed under sedation. However, if you prefer sedation, you can talk to your doctor about it. If there are no contraindications then it’s your decision.

Viable in several consecutive Natural Cycles:

There are no contraindications to performing several procedures in a row. However, when the attempts have been unsuccessful 5 or 6 times, the procedure is usually abandoned, as it is unlikely to work in this case.

More economical:

This procedure doesn’t require ovarian stimulation medication; therefore it’s cheaper than when these are needed.

Disadvantages of Natural Cycle IVF

This technique is more natural than ovarian stimulation, which requires hormone therapy.

However, after 5 or 6 unsuccessful treatments, the procedure is usually abandoned because the chances of it working are low.
