.. Yeah, that only works if you have a regular cycle. Many women don’t, and I never did, which led to a hysterectomy. A transplant recipient should avoid the number of blood transfusions that I needed. Sometimes I went a year with no cycle occurring, then had one continue for 14 months.
Personally, I think there should be some form of backup if you’re not looking to have children at the time you’re intimate. The Human body is affected by many things, and cycle-charting isn’t always completely accurate.
Also, the male half determines the baby’s sex.
I’m torn.
If men chose to copulate with leftists, Please Use Protection. Condoms, barriers, cold showers, scissors anything to keep those people from reproducing.
As for the rest, ...never mind.
There is truth to natural family planning contributing to the togetherness of a marriage. It’s also not foolproof but it works pretty well at avoiding fertility. Stress or travel or other things can still change up the predicted cycle. And sperm still can live for 5 days. But yes, having times to have sex and not have sex has kept orthodox Jewish couples’ passons alive.
But timing or positioning sex cannot determine gender. The chance is already 50-50 so this guy can’t prove they planned for and achieved their girl. He’s fooling himself.
Because men deliver so many babies.....
I am reminded of the old joke, “What do you call people who use natural birth control? Answer: Parents.”
I do not think I ever had a regular cycle unless I was on the pill. So keeping track of my cycle would never have worked. Many things can affect a woman’s cycle as well, even women who are usually regular. Since sperm can live in the body for days, a pregnancy can easily happen if ovulation is off from the calculated day.
I’ve seen many men use their personality as birth control.
I don’t know is it true or libel but once heard that Catholics has a disproportionately large percentage of retarded children comparing to the rest of the population precisely because of universally practicing this method which is not near efficient to be even considered contraception but mostly insures that if fertilization to take place it would be with a downgraded egg at its worst genetic shape.
The way I understand the mechanics of the process it sounds like a legit assumption.
I especially liked #4 in the list.
