(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).
Sun spots are actually cool spots on the surface of the sun that are associated with large magnetic fields. The surface of the sun has a temperature of 5800 Kelvin (what is that in Celsius or Fahrenheit?). A sunspot is typically 1600 Kevlin cooler. Sun spots are about 4000 Kelvin or over 7000 degrees Celsius.
