DescriptionWomen can spend ages finding the perfect man before starting a family. However, when it comes to biology, Mr Right could actually be wrong.

While a woman may want her partner to father her children, a study has found that her eggs might have other ideas. Researchers recruited 60 couples having IVF to see how compatible they were.

Women’s eggs release chemicals that appear to signal to sperm, encouraging them to swim over to make a baby. But for some women, the chemicals worked better for sperm from a man who wasn’t their partner.

Description (CNN)"Swipe right. Swipe left." On an evolutionary level, the finger flick of choice in the human mating game is often influenced by subconscious input from our most primal instincts.
In females, for example, hormones present at ovulation can drive a woman to choose a cocky, confident man with a slight stubble and more masculine features. Men can sniff out an ovulating woman just by smelling her T-shirt, while women appear to prefer the smell of a man with dissimilar genes, which could give her offspring a boost up the evolutionary ladder.

According to new research, different chemical signals are more apt to attract sperm from some biological males than others, allowing the eggs to essentially “choose” their sperm – and it’s not always that of their partners.
