When working on MSU I realized there was a problem. You can not find Trojan condoms that are non-latex condoms that done have lube. This was very concerning to me. Buying a medical condom was very expensive. So I emailed the Trojan company asking them about the lube, the pH and how it effects sperm. They informed me that it does not effect sperm because there is not lube on the inside of the condom. They said there condoms do not damage sperm. The lube pH was neutral. Great news for swayers!
Next I had to figure out the the instead cup. Can they be reused? Do they harm sperm? Well I found out from other forums that people do reuse instead cups for one entire af then throw them out. Just wash them out when you take them out and pop them back in. They are not made of Latex so they are safe for sperm.
Finally we were having trouble with pH strip from the pHion. The top box and the bottom box wouldn't match. What they told me was if one doesn't change but one does to read the one that does change. If both change and do not match then you take the average of the two. So since this is so confusing, I now recommend you get full range pH strips to tell you what box is correct. On the pHion strips. I still like the pHion strips because they give you more exact
