According to statistics, IVF success is equally good for women with one ovary and with two ovaries. The only thing that will make the IVF program different for those with one ovary is the number of hormonal drugs. Their amount can be increased for the single ovary to produce the required number of oocytes.
During the IVF preparation stage, a reproductologist will examine you thoroughly, perform multiple examinations and assess all the risks associated with the procedure. In general, the preparation for IVF directly depends on the reason for which the ovary was removed. For example, if you had your ovary removed because of a tumor, then the use of hormonal drugs to stimulate oocyte production will be contraindicated. However, this is not a reason to prohibit pregnancy and childbirth, so a fertility clinic may try to give you an IVF cycle using eggs that have been produced in a natural cycle.
Another reason women with one ovary have difficulty with IVF treatment is the presence of adhesions. This does not affect your fertility in any way, but after stimulation you may need a particularly careful and thorough puncture, which will only be done by a very experienced doctor.
The basis of successful ovarian stimulation is a competent assessment of a woman’s hormonal background. This allows choosing the most suitable hormonal stimulation system for the patient and obtaining the highest quality eggs. And it is the quality of eggs that ultimately determines the success of IVF.
If a woman after removing her ovaries has been trying to conceive for several years without success, undergoing treatment, including hormonal correction and small stimulation of ovulation, it becomes a serious reason to turn to an assisted reproductive technology clinic.
The main reason why women with removed ovaries cannot get pregnant is because of a disrupted ovulation pattern. In this case, the egg either does not mature to its full state or cannot leave the ovary and continue its journey. If the egg cannot leave the ovary, it becomes a functional cyst. This is due to the fact that the follicle, from which the egg emerges, cannot rupture. It is the formation of a large number of such cysts that becomes a very frequent cause of surgery on the reproductive system in women.
Quite often there is also a sterile form of polycystic ovarian cysts. This means that cysts are formed in the ovary, but despite this, the formation of eggs still occurs. However, ovulation can be disturbed, there can be unhealthy hormonal levels, which will be a serious obstacle to pregnancy.
When you have this adhesion process, it is very important, first of all, to return the hormonal background to normal. It is necessary to create a normal ovulation cycle so that a woman can get pregnant. This is usually followed by ovarian stimulation with hormonal medications, which is based on multiple tests. All of these tests are needed so that the reproductologist can correctly select medications that will not cause complications, and at the same time help the ovaries to produce more oocytes.
Often such stimulation is more than enough to allow a woman to get pregnant naturally without the use of assisted reproductive technology. However, if hyperstimulation does not help, fertility specialists recommend undergoing an IVF cycle. The need for surgical intervention is quite rare, and usually only in cases of prolonged reproductive system problems without a response to stimulation with hormones.
