Scientists now will make women more empowered. They have now developed a new contraceptive pill that promises to eliminate menstruation completely.
The pill developed by New Jersey-based Wyeth and called 'Anya', may help women to avoid unplanned pregnancies and the inconvenience of periods.
Critics have warned that oral contraceptives raise the risk of blood clots and breast cancer. They said continuous exposure to hormones might increase these risks and make it harder to spot potential health problems.
However, the manufacturer said the pill that has to be taken 365 days a year without a break was given to about 2,000 women for a study and just six had serious side effects such as prolonged bleeding or blood clots.
Like any other pill, 'Anya' avoids pregnancy by stopping ovulation, preventing eggs being released by copying the hormonal state of pregnancy. Numerous studies show this does not harm a woman's fertility because ovulation resumes when she stops taking the pill, it said.
A woman's body normally prepares for pregnancy every month by building up the lining of the womb. However, if the egg is unfertilised, the lining is shed in the process of menstruation. Because the pill stops ovulation, the womb lining does not build up in the normal way.
The 'withdrawal bleed' a woman gets when she takes a seven-day break from other contraceptive pills is in fact triggered simply by the sudden drop in hormones.
However, in the case of the new pill, there is no trigger for this process as there is no break and the lining remains without causing any problem to the woman.
Wyeth hopes to make the pill available for sale in the US next year and across the EU later. Analysts believe it could generate 170 million pounds annually in worldwide sales.
