Wonder why only 1% of the 300 million sperm released during sex manages to reach a woman’s uterus?
A recent study out of Britain appears to have the answer – it’s all because sperm have an “appalling” sense of direction! The study found that sperm avoids the “middle lane” of the female reproductive tract and crawls along the walls instead. They have difficulty turning corners and often crash into each other (and the walls) like a demolition derby. The sperm in this study that were successful were able to navigate this channel and the fluids within it.
The researchers suggest that with this new information, they are better able to select sperm that may be successful in conceiving through assisted reproductive technologies.
