Getting to grips with the numbers behind the man's part of the reproductive system. Although I'm a biologist, I rarely think much about what the cloudy white stuff contains, but in fact semen is far more complex than my endearing childhood image of mini tadpoles swimming around in thin wallpaper paste. There are many features of human semen that are very familiar to most people, but their importance isn't appreciated. For a start, the ejaculate isn't of a uniform consistency. As the man ejaculates, the first 'spurt' contains far more sperm than subsequent spurts.

Human Reproduction Problem Set
Clue is on a mission to help you understand your body, periods, ovulation, and so much more. Start tracking today. Only a tiny fraction of the sperm that entered the vagina make it to the fallopian tube. It takes about days for the fertilized egg to travel to the uterus and attach to the uterus in a process known as implantation. Sperm meets egg, egg meets uterus, and boom: pregnancy. Some of this information might also apply to conception that happens with the help of artificial reproductive technologies like in-vitro fertilization IVF , though we don't directly focus on that topic here.
Sperm release pathway
Pre cum, or pre ejaculate if we're being fancy, is one of those things you know exists if you have sex with people with penises. But, chances are you probably don't know what it actually is. No shade meant - I write about sex stuff every day and up until approx two minutes ago didn't have a damn clue what precum actually is.
Maybe things got a little out of hand last night. But if not—clean up! Flush your eyes with some lukewarm water. Make sure you cleanse the contact lenses with disinfecting solution before you put them back in.
