In my above remarks, I didn't address the morality, but was concerned for those trying to conceive, that they may choose wisely.
BTW, when my wife and I were trying to conceive, we avoided using lubricants around ovulation time. Back then, we didn't know about osmolality. We just figured it would work better to go natural.
I meant not to combat anything that you said; I notice a lot of over-scrupulosity regarding sexual matters on here and wanted to head off any confusion for another couple.
Like in an ectopic pregnancy, the Catholic church says that you may remove the "sick" portion of fallopian tube. The embryo passing away as a result is the secondary result of the primary action of treating a medical problem.
As above, a couple using lubricant who has trouble producing their own naturally, is not using the lubricant as a contraceptive, but only to address a medical problem.
Certainly your information is good to know for couples trying to conceive; I just wanted to provide reassurance to couples who may be concerned that using lubricant is in itself sinful.
