Oral contraception, mechanical contraception, and carbohydrate and lipid metabolism: a two-year study

International Journal of Fertility
V PribicevicZ Rajkovic


The carbohydrate and lipid metabolism of 100 women using an oral contraceptive (0.5 mg norgestrel + 0.05 mg ethinyl estradiol) and of 96 women using mechanical contraceptives was monitored over a 2-year period. The women had been screened for factors known to adversely affect carbohydrate and lipid metabolism. Two-hour oral glucose tolerance tests were performed at 6-month intervals during the study; serum insulin was determined at the same intervals in half the women. Triglycerides, total cholesterol, free fatty acids, and body weight were also measured. The study showed no significant differences in lipid metabolism nor in weight gain between women using oral or mechanical contraceptives. After 6 months the fasting glucose of women using oral contraceptives was significantly decreased; at 120 minutes, glucose and insulin levels were significantly increased in comparison to women using mechanical contraceptives. A greater percentage of oral contraceptive users had borderline-abnormal oral glucose tolerance tests but the abnormalities did not persist in the same individuals during the study. The incidence of a pathological oral glucose tolerance with oral contraceptives was 1%.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
