New male contraceptive succeeds in first month of testing
Currently, male contraceptives are limited only to condoms and vasectomy, unlike women who may choose different ways to avoid pregnancy. Researchers at the University of Washington in the United States have developed a male contraceptive, and the first clinical trials are promising.
The new male pill has been named as dimethandrolone undecanoate, or DMAU. Like the female oral contraceptives, DMAU has a combination of hormones to inhibit sperm production.
In a presentation at the annual conference of the Society of Endocrinology in March, the scientists showed data on research done with 100 volunteers between the ages of 18 and 50, with 83 completing all stages of the experiment.
Three different doses of the compound were tested for analysis. Participants were divided into groups of five, who received the medication or placebos. They took the pills daily over 28 days along with food intake, a requirement for the effectiveness of the substance.
When tested at the highest dose of 400 milligrams, the results indicated low levels of all hormones needed for sperm production. Low levels of testosterone can lead to loss of sexual desire and fatigue, but few volunteers had these effects.
However, all men who took the medication gained weight and dropped HDL, the good cholesterol levels. However, the researchers believe that these effects are not a cause for concern, since kidney and liver functions have remained normal.
New, more complex analyzes will be needed to check for undesirable medium- and long-term effects, especially, how long fertility takes to be fully restored with treatment discontinuation.

It may be said that a mixture of curiosity and mystery involves the practice of tantric sex. When one talks about it, one always speculates about the hours and hours that a couple spend fucking without reaching the climax. But what is behind this way of relating sexually? Tantra is a tribal philosophy that teaches to have in sexual experience a way to awaken Kundalini: the sacred energy of life.
The heart should beat at a rate between 60 and 100 beats per minute (bpm) at rest. Bradycardia occurs when the frequency drops below 60 bpm. Some cases of bradycardia are gradual and sometimes even physiological - as in trained athletes. Others, such as total atrioventricular blocks, endanger the person's life and it is precisely in these cases that a temporary pacemaker is indicated.
