Your healthy choice with premium reliability

If you want to prevent pregnancy without subjecting your body to the birth control pill and other compromises, the fertility computers of Valley-Electronics are for you. Based on your morning temperature taken orally the fertility computer determines your fertile days and shows you when you are ovulating by recording, analyzing and storing your menstrual cycle data. It monitors your daily status of fertility and will alert you on the days when intercourse may lead to pregnancy: on the day you ovulate – and five days before ovulation. 


The effectiveness of Lady-Comp has a clinically proven Pearl Index of 0.7, meaning it is 99.3% accurate. The pill, for example, has a Pearl-Index ranging from 0.1 to 0.9, while the coil’s is between 1 and 3. Lady-Comp is also ISO-certified and meets all CE (Conformité Européenne) essential requirements. 

It means that our fertility computers are the leaders in natural pregnancy prevention and family planning, with an accuracy equal to the most popular contraceptive methods, but without any side-effects.

"I use my lady comp for 12 years now and I think it's the best decision I have ever made for my body. No more hormones, just natural contraception in harmony with my body. And I can confirm that it works as I planned my pregnancy with it. I have recommended it to 2 friends one of whom tried for a baby for years without success. After using lady comp for a while she became pregnant as she was able to determine her fertile days. My other friend even used her lady comp to become pregnant on certain days of her cycle to determine the babies sex and it worked. We love our lady comp. It's easy and simply brilliant and well worth the money. How much would I have paid for the pill in 12 years? ;) Finally a big compliment to their fabulous customer service who responds very fast and is very friendly! Thumbs up! :)"
