It has an extremely severe drawback: the potential to cause clots and lead to death.

This accusations are not baseless; a study has linked the progestogen hormone called levonorgestrel, which is found in the newer forms of the Pill that Kurek happened to be taking, to being two-and-a-half more times more likely to experience clots than not taking oral contraceptives at all. Pills made up of the hormone estrogen likewise have this life-threatening potential. Latest study more comprehensive than others before it, links blood clots with newer contraceptive medication preparationsWhile many studies have got indicated links between contraceptive pills and possible blood clots, this specific one, conducted by experts from the University of Nottingham in the U.K., is thought to be more conclusive due to the fact that it didn’t make use of as many testing methods as history studies. For example, it is noted that studies from the past often used only healthy subjects , didn’t provide dosage information, or had a number of methodological approaches; their study took these factors into consideration and made changes accordingly.Of 1050 pregnancies, 1038 were singleton, and 12 twin. Follow-up rates were similar in the two groups. At 1 month, 856 women provided end result data; of the, 592 responded by phone or questionnaire and 264 attended face-to-encounter consultations with study midwives. At delivery, 981 provided end result data. However, 56 females were shed to follow-up or withdrew consent, and 13 who had fetal loss were not asked about smoking outcomes. Most self-reported nonsmokers permitted validation of this status. At delivery, validation rates had been 89 percent in the nicotine-substitute group and 92 percent in the placebo group; at one month, the rates had been 89 percent and 85 percent , respectively. Ascertainment was more full for birth outcomes than for smoking cigarettes outcomes . Participants in both groups had identical demographic characteristics .
