Alvergne and Lummaa are hoping the paper will spur further research.

"There are important limitations from previous studies, due to the fact few of them have been addressing the question as their main focus," Alvergne said.

Future research should focus on two questions in particular, she said: Does use of the pill affect marital relationship, satisfaction and durability; and does it affect the ability of couples to reproduce?

But Hurd thinks there are other trends changing how humans date, mate and reproduce far more radically than artificial hormone cycles.

"Probably the biggest change in my lifetime is how people meet each other: online and using programs that match them for compatibility," he said. "That's probably going to have a massive effect on how people end up dating and ultimately reproducing. Just because you like someone with a square jaw in the middle of your cycle probably doesn't affect who you end up with."
