In this review we illustrated the case of a woman who had perimenstrual exacerbations of Darier-White disease. The disease improved markedly with the use of continuously administered oral contraceptives. This striking improvement without side-effects supports the use of oral contraceptives in women with Darier-White disease, although its role should be investigated further using controlled stud...
The volume of the left and right breasts was measured daily in four nulliparous women during normal menstrual cycles and after the use of oral contraceptives. Breast volume increased significantly in the second half of both normal and contraceptive-controlled cycles. The mean total change in volume throughout the cycle was 100 ml under natural conditions and 66 ml on oral contraceptives.
4.1 Absorption, distribution, metabolism and excretion The disposition of various formulations of oral contraceptives used in humans differs. In general, both the oestrogenic and progestogenic compounds in combined oral contraceptives are absorbed by the gut and metabolized largely in the liver. A fraction of the absorbed dose of ethinyloestradiol and several progestogens is excreted in the bil...

OBJECTIVE To determine whether an expansion in private sector contraceptive supply is associated with increased socio-economic inequality in the modern contraceptive prevalence rate (MCPR inequality). METHODS Multiple rounds of Demographic and Health Surveys data were analysed for five countries that experienced an increase in the private sector supply of contraceptives: Morocco, Indonesia, K...
Introduction: Urine morphine test, in several countries is the most primarily available qualitative test for detecting opioid abusers. Since the users of illicit drugs attempt to defeat urine tests and there are also plenty of claims that usage of HD (high dose) contraceptive pills can result in false-negative results, we decided to design the present study to investigate the probable in vit...
Globally, data show that many women of reproductive age desire to use modern family planning methods. Many of these women do not have access to modern contraceptives, which is termed their 'unmet need' for contraception. In low- and middle-income countries where total fertility rates can be high and many women have undesired fertility, or wish to increase their inter-pregnancy intervals, access...
