History of the Birth Control Pill

The birth control pill, also known as the oral contraceptive pill (OCP), is a widely used form of contraception that revolutionized reproductive health. It was first developed and introduced in the 1960s, and its creation was driven by the need for a reliable and convenient method of contraception.

The history of the birth control pill dates back to the early 20th century when scientists began exploring the use of hormones for contraception. Researchers discovered that certain hormones, such as progesterone, could inhibit ovulation and prevent pregnancy. However, at that time, the technology to synthesize these hormones did not exist.

It wasn’t until the 1950s that advancements in chemistry and pharmaceutical technology enabled the production of synthetic hormones in large quantities. This breakthrough paved the way for the development of the birth control pill as we know it today.

One of the key figures in the development of the birth control pill was Dr. Gregory Pincus, an American biologist and researcher. In the 1950s, Pincus collaborated with a gynecologist named Dr. John Rock and a team of scientists to create the first oral contraceptive pill. They combined the synthetic hormone progesterone (progestin) with the hormone estrogen to create a pill that could effectively prevent pregnancy.

However, here’s where it gets interesting…. The decision to include a week of bleeding, commonly known as the “withdrawal bleed” or “pill-free week,” was primarily driven by societal and cultural factors rather than medical necessity. In the early stages of developing the pill, Dr. Rock, who was a devout Catholic, believed that having a withdrawal bleed would make the pill more acceptable to the Catholic Church and conservative society.

At that time, the Catholic Church condemned the use of contraceptives, but Dr. Rock believed that if the pill mimicked a woman’s natural menstrual cycle and included a week of bleeding, it would be more widely accepted. This concept was based on the idea that the pill would create an artificial cycle that resembled a woman’s normal menstrual pattern, making it appear less disruptive.

The inclusion of the pill-free week allowed women to experience a regular bleeding episode, similar to a menstrual period. This design choice aimed to give women a sense of reassurance that they were not pregnant and provided a familiar monthly rhythm.

Okay—is your mind blown now? Are you shocked that most pills include this fake period and make you bleed and use “feminine hygiene products,” for a week just to attempt to appease the Catholic Church? TBH, I’m not sure the ploy to appease the church even worked! And what about all the non-Catholics who take the pill this way because it’s how their health care provider prescribed it?

It’s important to note that the withdrawal bleed experienced during the pill-free week is not a true menstrual period but rather a hormone withdrawal response. When a woman takes the contraceptive pill continuously without the pill-free week, she can still suppress ovulation and prevent pregnancy while avoiding the withdrawal bleed.

Yes—you can skip the placebo (sugar) pills in the last week and start your next package. However, your insurance might not cover your refills if they think you aren’t due for them. 

Yes, this is all sorts of f’d up! Thanks, Dr. Rock! There are some brands of pills, fortunately, that are designed to take continuously. I usually recommend skipping the withdrawal bleeding for 3 packages and then having one bleed so that your uterine lining doesn’t become too thin, as this can cause irregular spotting.

Over time, medical understanding of the menstrual cycle and contraceptive methods has evolved, and researchers realized that there was no medical necessity for the pill-free week. 

However, the pattern of taking the pill for 21 days followed by a pill-free week became the standard regimen for oral contraceptive pills and has persisted due to familiarity and patient expectations. Many of my patients tell me they prefer to have a bleed to confirm that they are not pregnant and also to shed the lining of their uterus. But unfortunately, this bleed actually does not do either of these things! It just helps you hide the fact that you are on the pill and keeps you buying tampons and pads…. Now you know! As always, talk to your healthcare provider if you need more information specific to your health.
