I've read about this too! Some say the contractions help sperm travel faster, but does it really make a huge difference? I am currently pregnant and we didn't track this at all, but it's an interesting question.
There is some belief that uterine contractions during an orgasm can help draw the sperm upwards, which might slightly help. But honestly, it is not a scientific requirement for getting pregnant. Just try to enjoy the process without pressure.
To be very honest, no, an orgasm is not necessary to get pregnant. Conception happens when a healthy sperm meets the egg around your ovulation. Don't stress over these small details, just focus on keeping things relaxed.
Scientifically, there is no solid proof that having an orgasm increases your chances of conceiving. It's all about timing intercourse during your fertile window. Don't overthink it, just keep track of your ovulation dates.
I remember researching this so much when we were trying to conceive, and it made me so anxious! Some forums said yes, some said no. Honestly, it's just about ovulation timing, so please don't stress yourself out with these extra worries.
