Mother's testosterone key to having boys
A study published on a New Zealand web site said that women with high
testosterone levels are likely to have boys. The researchers went on to say that these women who have high testosterone levels are likely to display dominant personality characteristics, including displays of anger and anxiety, risk-taking, lower divorce rates and a tendency to be politically conservative.
University of Auckland Medical and Health Sciences researcher Dr Valerie Grant has already found a mammal's testosterone level may predispose her eggs to receive male sperm. This finding has not been proven in humans.
The research could lead parents to engineer a baby's gender through testosterone supplements, though the science is complex and much more research must be done, said Dr. Grant.
The study found that women pregnant with boys displayed anxious or angry during pregnancy, while women were more calm that were pregnant with girls. Women pregnant with boys have better spatial skills. - Tuesday, April 1, 2008
Obesity Research and Testosterone
Body Composition and Hormonal Adaptations Associated with Forskolin Consumption in Overweight and Obese Men
Commentary: Several clinical studies have been done on the effectiveness of forskolin in promoting weight loss in humans. One clinical study also observed forskolin's role in significantly increasing lean mass, bone mass, and testosterone in the subjects involved.
Coleus forskohlii is an important traditional Ayurvedic herb that has been a part of Indian medicine for centuries. In the 1970s, researchers isolated a chemically active ingredient in the herb and called it forskolin. Now available in supplement form, forskolin extract has been tested in a number of conditions. Forskolin extract is now found in Diet Rx appetite suppressant and Passion Rx sexual enhancer.
Another branded version of Coleus forskohlii is Sabinsa's ForsLean which is used in dietary supplements to promote lean body mass by reducing fat tissue and encouraging weight loss.
Abstract
Objective: This study examined the effect of Forskolin on body composition, testosterone, metabolic rate, and blood pressure in overweight and obese (BMI 26 kg/m2) men.
Research Methods and Procedure: Thirty subjects (Forskolin, n = 15; placebo, n = 15) were studied in a randomized, double-blind, placebo-controlled study for 12 weeks.
Results: Forskolin was shown to elicit favorable changes in body composition by
significantly decreasing body fat percentage (BF%) and fat mass (FM) as determined by DXA compared with the placebo group (p 0.05). Additionally, forskolin administration resulted in a change in bone mass for the 12-week trial compared with the placebo group (p 0.05). There was a trend toward a significant increase for lean body mass in the forskolin group compared with the placebo group (p = 0.097). Serum free testosterone levels were significantly increased in the forskolin group compared with the placebo group (p 0.05). The actual change in serum total testosterone concentration was not significantly different among groups, but it increased 16.77 33.77% in the forskolin group compared with a decrease of 1.08 18.35% in the placebo group.
Discussion: Oral ingestion of forskolin (250 mg of 10% forskolin extract twice a day) for a 12-week period was shown to favorably alter body composition while
concurrently increasing bone mass and serum free testosterone levels in overweight and obese men. The results indicate that forskolin is a possible therapeutic agent for the management and treatment of obesity.
