Q about DH ph

Hubbies ph was 6.5 this morning after abstaining for about a wk, he was to sick to take vita/herbs, but took 24hr suddafed for 4 days (but hasn't taken any for 36hrs).

Is a ph under 7 to low?

At what ph does it kill ALL the sperm?

Would a ph of 6 be better for a girl sway?

NO, it's just one of those things. pH can vary by quite a bit, due to illness and the Sudafed may have affected it as well.

A lot of ladies would be thrilled if their DH's pH was 6.5 so just go with it - sperm can still survive in that pH.
