A day in the life of sperm...
Ok this is totally COMPLETELY connecting the dots in different orbits, universes and galaxies...but hey...why not?
I read this article:
Sperm Use Heat Sensors To Find The Egg; Weizmann Institute Research Contributes To Understanding Of Human Fertilization
and later in the day I thought, "hmmm somewhere I remember reading here or in IG folklore, that higher progesterone cycles are slightly higher on your chart, temp-wise". So I thought, maybe (!) the hotter conditions of a higher progesterone cycle get those XX sperm in gear towards their heat source!! LOL :cool:
