Sunday, February 05, 2006 Was chatting with Adrian on MSN messenger in the afternoon and the conversation somehow went like this...Adrian: So you don't go swimming or jogging anymore ah? Me: Ah.. I got my period, how to swim or jog? Adrian: Having period, cannot jog meh? Me: Cannot, not safe. Supposedly will add a lil trauma to the uterus at this delicate period of time. Adrian: Huh? Then, I realised that Adrian has no idea what menstruation really is. And most probably, so does 70% of the male population and 20% of the female population. These people see menstruation as just a bloody mess that women pass out of their bodies every month. They would also link it to PMS - Pre-Menstrual Syndrome, which turns even the sweetest, cutest lady into a terrifying orgish creature. And so, I proceeded to give Adrian a brief lesson, from a scientific point of view, what menstruation really is. Firstly, let's get acquainted with some female sexual reproductive organs. ![]() So what goes on in the above when menstruation sets in? There are actually 2 cycles in menstruation - The Ovarian Cycle and The Uterine Cycle. What we are looking at here mainly is The Uterine Cycle. Notice that blue-shaded region labelled as the endometrium, aka uterine lining? The uterine lining is a thin layer of tissue which will grow and thicken as it nears ovulation (the release of the egg from the ovary into the fallopian tube and into the uterine cavity). Its growth and maintenence are triggered by two female sex hormones known as progesterone and oestrogen. So when the egg is released and meets with a sperm, it will be fertilised and form a zygote, and then into an embryo which will then proceed to embed itself into the thick spongy uterine lining. Tada! Pregnancy occurs! Then again, if the egg is released and does not meet with any sperm, it will stay in the cavity for at most a day. Then the uterine lining will be shed and disintegrate together with the unfertilised egg and some mucus, and passed out through the vagina as the usual bloody mess we see. And ladies, it is normal to pass out pieces of blood clots during menses because these blood clots are actually pieces of the shed off uterine lining. After finishing explaining to Adrian, he said he felt like a little student who just had a sex education lesson from a teacher. Haha... So like I said, when the uterine lining is shed during menses, the uterus is pretty fragile and delicate, and so I would prefer to keep sports to a minimum during that time of the month. *****
Good news for y'all men out there. Studies have shown that abstinence from sex or masturbation is detrimental to the health. " "The perception is that if a man abstains for a long time, he'll improve his fertility," he says. "That's true to a point - five days - but beyond that, things start to go downhill a bit. "The longer the sperm hang around in the male reproductive tract, they begin to degenerate, die, and release free radicals, which will then damage other sperm. It's a chain reaction - the fresh sperm coming down the tubes enter an environment of free radicals and get damaged." In the next three months, not just will power will be tested. There are other physiological effects outside of fertility. " For the full report, turn to page L10 of today's The Sunday Times Lifestyle section - Better Laid Than Never. ![]() People dressed as sperm run across a road during a campaign promoting the use of condoms in Colombia. Yeah! Keep the sperm moving! It's good for you. So go ahead, guys! You've got another good reason to masturbate/make love. Go wank! Go jerk off! Go make more babies! Go have protected sex! Ermm... I don't really approve the idea of casual sex, hence the tiny font. *cringes*
