SEX HEALTH - MALE PHYSIOLOGY ARTICLE

MALE PHYSIOLOGY

Whether or not you ever become a father, the male reproductive system is designed to help you do just that. Your male sex organs produce, store and deliver millions of tadpole-shaped spermatozoa (‘sperm’), each primed to fertilise a female’s egg after sex.
Many of the most dramatic physical and emotional changes you experience as you become an adult are driven by chemicals that your glands and other tissues produce, called male sex hormones or androgens. Your hypothalamus and your pituitary gland, at the base of your brain, control the release and levels of these hormones. Testosterone, which is mostly produced in the testes, is the most potent androgen in men.
PubertyPuberty, the transition from child to sexually mature adult, usually takes between about 2 to 5 years. A growth spurt that could kick in between the ages of 10 and 16 may be the first outward sign for boys. Testosterone secretion surges, stimulating the growth of the beard, body hair, bone, muscle and prostate gland (your prostate produces some of the fluid that mixes with sperm when you ejaculate). Testosterone also fuels powerful emotional urges, most notably your sex drive and aggression. Sperm journeyTestosterone also fosters the development of your sex organs, including your testes, where sperm is produced. From the testes, sperm move through the epididymis, which is five metres of tightly coiled tubing tucked up behind your testes. In the epididymis, sperm develop the essential ability to move or swim (become ‘motile’). They are stored in the epididymis until you have an erection. In very simple terms, when you have an orgasm, muscle contractions move the sperm along a series of ducts where they collect fluids that mingle to become semen. The sperm-bearing semen is pushed out through the penis during ejaculation.
More changesDuring puberty, as your glands become active, pumping out more hormones, you may grow:– more muscular– taller, broad-shouldered and heavier – a deeper voice – pubic hair, underarm hair and chest hair– more sweaty– oilier skin and pimples.
Along with the rest of your body, your penis and testes grow bigger and you get erections – your penis gets hard, sometimes when you least expect it. With puberty, as your sperm production begins you might ejaculate when you get an erection, releasing semen. Sometimes this happens while you sleep; it’s called a ‘wet dream’. It’s a normal sign that the plumbing in your reproductive system works.
After age 40, male testosterone levels fall very gradually. In some older men, testosterone levels get too low, causing health problems. Older men are also more likely to suffer from conditions such as prostate disease and erectile dysfunction. Erectile dysfunction can affect young men too, but usually due to different causes.

Even if you never have a baby, your body's capacity to conceive and carry children drives many of the important physical changes you experience throughout your life. Hormones, chemicals produced by your glands or other tissues, control these changes and others, such as the emotions you experience as you mature into adulthood.
PubertyPuberty, the transition to sexual maturity, usually takes between 2 to 5 years. Girls usually start puberty between ages 12 and 15, but sometimes as young as 8. During puberty the female sex hormone oestrogen fosters the growth of the sex organs: the ovaries, Fallopian tube, and uterus. This is when your ovaries - your reproductive glands - start to fully function by releasing a mature egg each month. The lining of your uterus (or womb) builds up each month, ready to support a fertilised egg. The egg is carried into your Fallopian tube but if no sperm fertilises that egg, the uterine lining sheds, mixed with blood, during your menstrual period. Among other changes, oestrogen also makes you:- grow tall quickly- develop breasts- grow pubic hair and underarm hair- get broader hips- perspire more- get oily skin, and maybe pimples- grow coarser hair on your legs- have vaginal secretions.
PregnancyIf you get pregnant, your body undergoes many more, dramatic changes, regulated by a variety of hormones. This includes the growth of the placenta within the uterus. The placenta acts like a spongy lifeline carrying nutrients, gases and wastes to and from the embryo. Externally, the most obvious changes to your body include the expansion of your abdomen to accommodate the foetus, weight gain and bigger breasts.
MenopauseMenopause is when you stop menstruating and usually occurs between ages 42 and 56. Your ovaries start producing less oestrogen in the years leading up to your last period and your menstrual cycle may become unpredictable - irregular, lighter or heavier, until they stop altogether. This lead-up to menopause is called perimenopause. You might also experience symptoms like hot flushes, weight gain, night sweats and mood swings, although some women have no such problems. For those who do, treatments to ease the symptoms include HRT (hormone replacement therapy) and natural therapies. Without the protective effects of oestrogen, after menopause women may be more vulnerable to other health conditions, such as osteoporosis (thinning bones) and heart disease.
Sometimes serious health problems may cause a young woman to experience early menopause, also called premature ovarian failure. This is when a woman stops ovulating, or producing eggs, or ovulation may become infrequent and unpredictable. Health problems that might bring on early menopause could include causes such as dysfunctional ovaries, difficulties with the pituitary gland, which releases hormones, radiation treatment or chemotherapy.
