THE SPERM TRACT AND THE PRODUCTION OF SEMEN

From its site of production in the testes, the sperm must travel through the sperm tract to reach the outside of the body. As it does so, the various components that make up the seminal fluid are added to the sperm. The sperm tract, illustrated in figure 3.7, consists of a number of ducts including the epididymis, the vas deferens, the ejaculatory duct, and the urethra. In addition, a number of glands that secrete various fluids join the sperm tract through a series of small ducts.

After being produced in the seminiferous tubules, the sperm are stored in the epididymis, which is a highly coiled, interconnected network of seminiferous tubules lying in the upper part of the testes. As the sperm mature in the epididymis, they become capable of movement as the neck of each sperm becomes flexible.

The vas deferens carries the sperm from the epididymis to the ejacu-latory duct. At this point, the ducts of the seminal vesicles join the sperm tract and provide a viscous, alkaline secretion containing fructose and prostaglandins. The fructose, a sugar, is a source of energy for the sperm; the prostaglandins stimulate uterine contractions and help the sperm move to the female's fallopian tubes where fertilization takes place. The prostate gland surrounds the ejaculatory duct at the place where it becomes the urethra. It secretes a milky fluid that aids in sperm motility. The fluid contains, among other things, a large concentration of bicarbonate ions that gives the semen its alkaline pH. The alkaline nature of the seminal vesicle fluid and the prostate gland fluid reduces the acidity present in the urinary system, which is joined to the sperm tract at the urethra. This is particularly important since sperm motility is adversely affected by an acidic environment. Finally, the bulbourethral glands (Cowper's glands) secrete a mucuslike substance that provides lubrication for the urethra.

The secretions just described are called seminal fluid, and the combination of sperm and seminal fluid is called semen. Since there frequently is confusion as to the distinction between sperm and semen, it is worthwhile to point out that while sperm are under the careful hormonal control previously described, the seminal fluid is produced by the body as needed and is not affected by hormonal levels. Also important is the fact that the semen contains an antibiotic substance called seminalplasmin. Were it not for seminalplasmin, seminal bacteria would almost always infect women's vaginas, making sexual intercourse a routine health hazard.

WHAT MAKES A WOMAN FEEL CONNECTED AND INTIMATE: WOMEN FEEL CONNECTED AND INTIMATE WHEN A MAN COMMUNICATES WITH US


For women, connection is very much about communication. Most women are traditionally more verbal than most men, so one of the fastest and most effective ways to connect with a woman is with words.

What Women Want Men to Know:

Words build a bridge between a man's inner world and the heart of the woman he loves. They create instant intimacy.

What do women want men to communicate about? Of course, you already know the answer: EVERYTHING! We want to know about your work and your worries, your dreams and your fears, your ups and your downs. Remember: Emotional connection is created when you share what's inside of you with your partner, and communication is the only way to do that.

I'm well aware that men have many issues about opening up and revealing themselves. We'll talk more about these in our communication section. The point here is just to remind men of how powerful communication is in helping your woman feel connected to you. "When my boyfriend shares things with me he doesn't share with anyone else," one woman told me, "it makes me feel special and loved. I know he wouldn't open up to me like that if he didn't really cherish me."

If communicating with a woman makes her feel connected, not communicating with her about important things definitely creates a feeling of being disconnected. Here's what women expressed about this:

"When a man keeps things from me, and doesn't share something important that is going on with him, I feel disconnected and discounted, like we're in two different worlds, and he's put a wall between us."

"Withholding information is the biggest turnoff to me. I don't understand how my husband expects me to want to have sex when I know he hasn't been sharing much about himself. If he wants me to open up, I need him to open up."

What Women Want Men to Know:

Withholding feelings or information from your partner is not a harmless act It creates a sense of disconnection between you and eventually destroys the intimacy.
