What a great question. Overall PH inhibiting Intra-Uterine Insemination (IUI) success is not a popular topic in the Reproductive Endocrinology world but worth considering as a hidden barrier. During IUI, sperm is prepped by concentrating it down and adding a sugary “fuel” to aid the sperm as they travel to the hopefully waiting egg or eggs.
The concern with an acidic PH is that the acidity will destroy some sperm as they travel to the egg. Generally speaking a PH between 7.35 and 7.45 is considered to be more alkaline and more supportive of optimal health.
Therefore tracking your PH is worthwhile but in general you should look to more typical reasons why IUI is not working. For instance 1.) How many follicles were 18mm or larger during your last ultrasound prior to the IUI? 2.) How many sperm were inseminated? 3.) Did your physician provide any concerns about the timing of the insemination?
(Sometimes REs adjust what day they inseminate after one or two trials if they think you may have started to ovulate a little sooner or later then your blood work showed.) 4.) How old are you? 5.) Did you try IUI monthly without a break? (There is little scientific literature to back this but many in the fertility industry believe in a cumulative effect of back to back fertility treatments.)
So to answer your question, your body’s PH is worthwhile to track. However we do believe that more traditional IUI inhibiting factors should be considered when an IUI fails. As always discuss your concerns with your RE.
