The effects are so palpable that a recent trial of male birth control was put on hold after many men dropped out because they felt terrible. Now, this study proves that their quality of life is significantly affected if they take oral contraceptives.
For a period of three months, the participants were given either birth control pills or placebos.
He said: 'This might in some cases be a contributing cause of low compliance and irregular use of contraceptive pills.
Intake of oral contraceptive pills may negatively impact healthy womens general quality of life and their well-being, self-control and energy levels, a new study warns.
"Despite the fact that an estimated 100 million women around the world use contraceptive pills we know surprisingly little today about the pill's effect on women's health", said Angelica Hirschberg, the lead author of the research.
A team of British and Swedish researchers also found that the contraceptive can lower energy levels - but found no links to depression. They were randomly assigned to either placebo pills or hormonal contraception containing ethinylestradiol and levonorgestrel, the most common form of combined birth control in Sweden, where the study took place.
This is recommended as the first choice for most women as it is considered to carry the least risk of blood clots - one of the most feared side-effects. However, it was unable to establish a causal link between the pill and depression.
Researchers discovered that the women who took the real pills felt different, as compared to those who received a placebo.
The former chemical is found in two of the best known brands available to women, Microgynon and Rigevidon.
"We do not want women to stop using oral contraceptives due to our results but if a woman is anxious about negative influence on mood and life quality she should discuss this with a doctor", noted Hirschberg.
The researchers caution, though, that the effect was small - and it's important to remember that only one method of contraception was studied, so the results can not be applied more broadly. As a result, some of these women turn to non-hormonal methods of birth control such as diaphragms, copper IUDs, condoms and cervical caps.
The findings reinforce earlier research and anecdotal claims that women are struggling with the side effects of the contraceptive pill.
Dr. Lindén Hirschberg says that the findings should not discourage doctors from prescribing birth control, but that they should discuss these potential effects with patients-"particularly with those who have previous experience of mood disorders", she told Health.com via email.
