Menstrual cycles and conception are directly related. To do any fertility test on a woman, you need to know how her menstrual cycles work. All the internal and external changes that occur during each period are determined at conception.

Therefore, it’s important to know how ovulation works in a woman’s body.  Remember, ovulation is the process by which the female body releases an egg.

Reproduction occurs when sperm fertilizes the egg. In this article, you’ll learn interesting facts that you might not have known about ovulation, menstrual cycles, and fertility.

“Age is an important factor when it comes to female fertility. The potential for reproduction depends on the ovarian reserves. As you get older, these reserves decrease. This means that there are fewer eggs. Over the years, their quality goes down as well.”

–Catriona Harvey Jenner–

  • The life of the egg is very short. Once it leaves the ovary and goes into the woman’s body, it only lives for 4 to 12 hours. If you want to conceive, you need to take this time into account. It’ll make it easier for the sperm and egg to join.
  • You can recognize that you’re ovulating by changes in your behavior. During these days, the woman’s body prepares to reproduce. She will seem extra feminine.
  • Ovulation triggers her sense of smell. During her menstrual cycle, there are days when the woman’s sense of smell sharpens. It’ll be much easier to sense male hormones. Also, a man’s particular smell can also be very attractive.
