the sperm. This secretion constitutes more than half the bulk of semen. Semen is a grayish white, sticky mixture that consists of sperm and other fluids from the accessory glands. The prostate gland secretes a milky, alkaline fluid that is essential in the neutralization of the acidity in the vagina during intercourse. The Cowper’s glands secrete an alkaline, mucous-containing fluid into the penile urethra that is lubricating and protective and adds to the bulk of the semen. An ejaculation is the process by which semen is ejected from the body and is a spinal reflex like an erection. An orgasm, which is an intense pleasurable sensation, usually follows an ejaculation. Although, some men report that for them ejaculation and orgasms do not always occur simultaneously. The sex

glands of males include the hypothalamus, the anterior pituitary gland, the testes, and the adrenal glands. Their hormones (chemical regulators) are responsible for sperm cell production and for the evolution and preservation of a man’s sexual traits. Testicular hormones are necessary for the prenatal growth and differentiation of the male genitalia. The hypothalamus controls the pituitary gland and the pituitary gland responds by stimulating the sex glands. Androgens (male sex hormones) are produced in the testes, with the most abundant being testosterone. At puberty and thereafter, testosterone is responsible for the development and maintenance of male secondary sex characteristics such as; the growth and development of male genitalia; and the pattern of hair growth. The

development of a low-pitched voices; the thickness and texture of the skin; and the increased muscle and bone mass.Sleeplessness, a decreased interest in sex, and an inability of concentration, depression, loss of appetite and fatigue as stated by the author Curtis Byer characterize the male climacteric (mid-life crisis or transition). While other changes can result from diseases as the man progresses in age. One of the most common types of cancers in younger men is testicular cancer and in older men prostate cancer. Prostate cancer is one of the leading causes of death amoung American men. Some ways that men can keep their reproductive system healthy is to exercise, trim the fat out of their daily diet, which tends to irritate the prostate and increase cancer risk. Take plenty

of vitamin A and vitamin C, for the maintenance of the reproductive system. Eat zinc, to help contribute to the quantity of ejaculate. Stay away from nicotine, which destroys vitamin C. Routinely do testicular self-exams and check mate cancer with regular check-ups. In addition, practice safe sex to avoid the transmission of STD’s (sexually transmitted diseases). For added protection use condoms coated with nonoxynol-9, which is a spermicide that has been shown to help kill HIV. For a man to be successfully health-savvy he must read the signals that are both subtle and conflicting from his body. The human body while awe-inspiring in its complexity, is not as hard to take care of as we may think. “For we are lovers of the beautiful, yet with simplicity, and we cultivate the

mind without loss of manliness.” – Pericles
