ABSTRACT:
FIELD OF THE INVENTION
The invention relates to compositions that can ameliorate or prevent male hormone deficiency and are useful as dietary supplements. These compositions contain yeast cells obtainable by growth in electromagnetic fields with specific frequencies and field strengths.
BACKGROUND OF THE INVENTION
Testosterone levels in men decline with age. Testosterone deficiency has been associated with hip fracture and reduced bone mass in older men. Testosterone replacement therapy has been used to improve the level of this hormone.
Among various remedies, a number of botanical preparations have been used to restore erectile function, including ginseng, Ginkgo biloba, yohimbine (
Pausinytalia yohimbe
), and muira puama (
Ptychopetoalum olacoides
), a South American plant. L-arginine, a precursor of nitric oxide, and androstenedione also have application in male sexual function. Males who received testosterone had a significant increase in bioavailable testosterone concentration, hematocrit, right hand muscle strength and osteocalcin concentration. Treatment with the estrogen antagonist tamoxifen has been also shown to increase serum levels of testosterone in both mammal and oligozoospermic men. In addition, the anti-estrogen clomiphene is used to treat decreased libido, hypogonadotrophic hypogonadism and associated infertility.
SUMMARY OF THE INVENTION
This invention is based on the discovery that certain yeast cells can be activated by electromagnetic fields having specific frequencies and field strengths to increase serum levels of testosterone. Compositions comprising these activated yeast cells can therefore be used for treating male hormone deficiency or associated diseases in a subject (e.g., a human).
This invention embraces a composition comprising a plurality of yeast cells that have been cultured in an alternating electric field having a frequency in the range of about 10500 to 12000 MHz (e.g., 11210-11250 MHz) and a field strength in the range of about 100 to 600 mV/cm (e.g., 150-520 mV/cm). The yeast cells are cultured for a period of time sufficient to activate said plurality of yeast cells to treat male hormone deficiency or associated diseases in a subject. For instance, the cultured yeast cells when ingested can stimulate the growth (e.g., by at least 10% such as 20%, 30%, 40%, 50%, one fold, five fold, ten fold, and fifteen fold) of the prostate, seminal vesicle, and glandulae preputiales, and increase (e.g., by at least 10% such as 20% and 200%) the secretion of testosterone in a mammal.
In one embodiment, the frequency and/or the field strength of the alternating electric field can be altered within the aforementioned ranges during said period of time. In other words, the yeast cells are exposed to a series of electromagnetic fields. An exemplary period of time is about 50-200 hours (e.g., 60-145 hours).
Also included in this invention is a composition comprising a plurality of yeast cells that have been cultured under acidic conditions in an alternating electric field having a frequency in the range of about 11000 to 12000 MHz (e.g., 11200-11250 MHz) and a field strength in the range of about 200 to 600 mV/cm (e.g., 240-520 mV/cm). In one embodiment, the yeast cells are exposed to a series of electromagnetic fields. An exemplary period of time is about 50-100 hours (e.g., 56-84 hours).
Yeast cells that can be included in this composition are available from the China General Microbiological Culture Collection Center (“CGMCC”), a depository recognized under the Budapest Treaty (China Committee for Culture Collection of Microorganisms, Institute of Microbiology, Chinese Academy of Sciences, Haidian, P.O. Box 2714, Beijing, 100080, China). Useful yeast species include, but are not limited to, those commonly used in food and pharmaceutical industries, such as

, and
Saccharomycodes sinenses
. For instance, the yeast cells can be of the strain
