Q1. Read the information about the trialling of the first contraceptive pill. The Pill was developed by a team of scientists led by Gregory Pincus. The team needed to carry out large scale trials on humans.
In the summer of 1955, Pincus visited the island of Puerto Rico. Puerto Rico is one of the most densely populated areas in the world. Officials supported birth control as a form of population control. The women in Puerto Rico were mainly poor and uneducated.
The scientists selected a pill with a high dose of hormones. The Pill was found to be 100 % effective when taken properly. But 17 % of the women in the study complained of side effects.
The women in the trial had been told only that they were taking a drug that prevented pregnancy. They had not been told that the Pill was experimental or that there was a chance of dangerous side effects.

Evaluate the issues involved with methods used by Pincus in trialling the contraceptive pill.

It has been an issue in the FDA for over five years now and still the conflict goes on. On the side for prescription Plan B, researchers focus on birth control needing a prescription and the safety of self-administration.

The use of drospirenone in the birth control showed to cause venous thromboembolism, which are blood clots that could be very deadly, even in young healthy women. Yasmin and Yaz warnings did not include the risk of thromboembolism. Therefore, patients were unaware of the risk and were not able to make sound decisions about the birth controls. Two studies were conducted, one by the British Medical Association, where researcher found a twofold increased risk of non-fatal venous thromboembolism in women using drospirenone-containing contraceptives.

    Injectable Birth Control Tools

    However, most of the methods have side effects. Ranging from just breast tenderness to fatal conditions such as stroke and breast cancer. This means many other factors must be taken into consideration before opting for a particular hormonal method. These include age, lifestyle, medical history, somatotype and socio-economic well-being. These factors have an even greater important for hormonal methods containing oestrogen. This is since oestrogen is thought to increase the risk of blood clots and blood pressure. This can make it quite dangerous for some individuals to use. On the other hand, the progestin only methods can be used by a much wider array of individuals offering a much safer alternative. They can be used by women that breast feed, are smokers over age of 35, have high blood pressure etc. Again, these factors must be accounted for as they will affect the type of contraception used. Resultantly affecting the side-affects experienced for e.g. increased chance of blood clots, increased blood pressure, diabetes, depression and in some cases even cause irreversible decrease in bone…

    Abortion Persuasive Speech

    The combination pills are made of the hormones estrogen and progestin, both of which are hormones found in a woman’s body naturally. The hormones in the pill keep the eggs from leaving the ovaries and also thicken the cervical mucus to keep sperm from getting near the eggs. If a woman is taking the pill as directed, then there is only a one in one-hundred chance that she will become pregnant. If a woman is not taking the pill as directed there is a nine-in-one-hundred chance that she will still become pregnant. This means that the birth control pill is rather effective. There are many risks and side effects that come with the pill, but many women are able to adjust with few or no problems. The more common side effects are bleeding between periods, breast tenderness, and nausea and vomiting. As with all unnatural birth control, there is a risk that a woman’s menstrual cycle will not re-regulate, or the risk of losing fertility. This happens to many women, especially when taking it for non-birth-controlling purposes (“Birth…

    The Birth Control Pill Essay Example

    Most women have taken it, or know someone who has taken it. And as for men, at least have had a girlfriend who has taken it. But we never think of how it works, or where it comes from. Think about it...."How does a tiny pill prevent pregnancy?". Birth control methods date all the way back to 384 BC, when Aristotle was thought to be the first person to use chemicals such as cedar oil, lead ointment, or frankincense oil as spermicides. If you look at the timeline on my first website, you can read some pretty wacky ideas to prevent a baby. But not until the 1900s, we were able to come up with the idea of using hormones to "trick" the body to think it was already pregnant. Therefore, the female would not ovulate at all.…
