FERTILITY
This method is the most reliable. It doesn’t matter whether the female has one or two ovaries, but it does help if the male’s sperm-count is high. It’s essential that neither parties take medicine of any sort, or douches.
The female is fertile for three days (because of the midnight factor this can be extended to five).
These three days are usually the 14th, 15th, and 16th from when her period first started. The male
must have no ejection for 36 hours beforehand (as this is how long it takes for male-sperms to be fully fertile again).
If the female takes her temperature every morning (before getting out of bed) she will find that her temperature drops suddenly to 36.6c , and then the next day it is up to 37.2c , which is when the ovum is in the Fallopian tube. The male-sperm consists of ‘female’ and ‘male’ sperms. The ‘male’
sperms having a slightly bigger head (like tadpoles) go faster, but their life is shorter, so if the ovum
is in or near the Fallopian tube the ‘female’ will win being slower, but having a longer life .
