The Use Of Contraceptives (Part 7) – Knowing The Fertile Days (cont.)
The Use Of Contraceptives (Part 7) – Knowing The Fertile Days (cont.): I don’t know if it is good news or not that from the time of puberty until the day a man dies, he is always potentially fertile. And this is a fact!
Research shows that an average male will produce roughly 525 billion sperm cells over a lifetime. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Without a woman’s single contribution of one VIABLE EGG CELL that survives only within 24 hours of its release, a man’s day-in, day-out, year-in, year-out fertility is completely useless.
If you ever view sperm cells under magnification, you will see that they resemble tiny tadpoles. I still remember the drawing those days in our biology class and how we were told that the tails whip back and forth with astonishing speed, propelling them toward nothing else but the egg. Amazingly, only one sperm cell will end up fertilizing the egg.
Keep this always in mind. A man’s sperm is very sensitive to its environment and unless it is protected, the environment of the vagina is bad for it. This is because most of the time, a woman’s vagina secretions are acidic and actively hostile to sperm.
You know why?
Simple! It is to ensure against the possibility of sperm living and aging in the woman’s reproductive track.
Can we digress a little? Thank you!
It’s is like there is something about the fact that only fresh sperm is used. In a man’s body, one way it gets rid of older sperm is the phenomenon of involuntary orgasm: the so-called wet dream. Even without an involuntary ejaculation, nature has another way of removing aging sperm by leaking them out in the urine. This is why sperm are usually found in the urine of normally fertile men.
Back to what we were saying . . . about a woman’s vagina secretions that is acidic and actively hostile to sperm.
Now, even if there is one sperm that proved “stubborn” by withstanding this ‘almighty-acidic-python-dance’ in the vagina, nature provides a second and more effective mechanism to insure that sperm won’t travel beyond the vagina canal. There is a secretion in the cervix, a mucus secretion that acts as a barrier.
What is mucus?
Let me explain it with simple examples. If someone asked you, what is the mucus that occurs in the mouth? The answer will be saliva. Or, what is the mucus that occurs in the nose? The answer will be catarrh. So also, the vagina/cervix has its own mucus.
Many women see some kind of mucus every day. Sometimes it is sticky or tacky like your white tooth paste or pap (custard); at other times it is thin, watery, or cloudy like a creamy hand lotion; other times and this is the important moment, the mucus becomes slippery, lubricative like the catarrh in the nose or like the white part of an uncooked egg. (We shall still give more details on mucus in subsequent classes).
The sticky tacky, mucus does not only prevent the sperm from traveling towards the uterus, it makes sure that they are dead. But things change dramatically as the time of ovulation approaches: Mucus that was once a barrier give way for mucus that will serve as aid to not just the survival of the sperm but for it to get to its targeted destination. We call this mucus, FERTILE MUCUS. This is the slippery lubricative mucus. Unless fertile mucus is present, the sperm is unable to fertilize the egg and it cannot cause conception.
See you next class!
I love you all!
