(Reprinted from Pygmy Goat WORLD magazine with permission) Sterility in the buck is usually the exception rather than the norm and is usually temporary. Male fertility is affected by such things as age, maturity, nutritional status, general health, endocrine balance and normality of sex organs. Sperm quality , nutrition, body weight, maturity, stress, disease, mating frequency, seasonal and climatic changes, and management also play roles in male fertility.
The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).
The spectacular picture to the left shows the sun's granular surface, a few surface flares, and an amazing edge prominence called the Handle. The sun's surface temperature is 5,800 Kelvin or about 10,000 Â°F. But... the temperature of its core is 15,700,000 Kelvin! The sun's diameter is 865,000 miles, which is 109 times that of the earth. Its surface area is approximately 12,000 times that of the earth. The sun's mass is 333,000 times that of earth and is about 99.9% of the total mass of our whole solar system. 73% of the sun's mass is hydrogen while 25% is helium.
