What is one feature of the oral contraceptive pill?

One feature of the oral contraceptive pill is that it stops ovulation. This is the primary mechanism by which it prevents pregnancy. The hormones in the pill work by inhibiting the release of eggs from the ovaries, meaning that ovulation does not occur during the menstrual cycle. Without ovulation, there is no egg available for fertilization by sperm, which significantly reduces the chance of pregnancy.

Additionally, the oral contraceptive pill can also thicken the cervical mucus, making it more difficult for sperm to enter the uterus, and it can alter the lining of the uterus to hinder implantation in case conception does occur. However, its most crucial role is in preventing ovulation altogether, which is why this feature is fundamental to its function as a contraceptive method.
