Maclaurin used Newton's theory to show that a smooth sphere covered by a sufficiently deep ocean under the tidal force of a single deforming body is a prolate spheroid (essentially a three-dimensional oval) with major axis directed toward the deforming body. Maclaurin was the first to write about the Earth's rotational effects on motion. Euler realized that the tidal force's horizontal component (more than the vertical) drives the tide. In 1744 Jean le Rond d'Alembert studied tidal equations for the atmosphere which did not include rotation.
If a young man's low testosterone is a problem for a couple trying to get pregnant , gonadotropin injections may be an option in some cases. These are hormones that signal the body to produce more testosterone. This may increase the sperm count. Hedges also describes implantable testosterone pellets, a relatively new form of treatment in which several pellets are placed under the skin of the buttocks, where they release testosterone over the course of about three to four months. Injections and nasal gels may be other options for some men.
Many non-organic foods on the market contain harmful chemicals, pesticides or added hormones that act as xenoestrogens if you consume them. Always try to avoid non organic and processed foods in general. This is especially important when purchasing meat products. If you go to any grocery store in the US and look at the meat section. If you see a pack of chicken breasts that are huge but a very cheap you can be pretty sure that they aren’t completely natural. You should always purchase meat and poultry that is “hormone free”. You should try to decrease your consumption of processed foods and look to eat more organic fruit and vegetables to reduce your risks of eating with additional hormones and pesticides.
