List of Foods Having Aphrodisiac Qualities

Apart from satisfying our hunger and taste buds, foods also have fringe benefits to them. Some foods are claimed to be able to increase arousal in both male and female. Here are the theories behind the aphrodisiac potential foods.

Arousal for Men
There are some components in oysters that have aphrodisiac qualities. For one thing, oysters contain varying levels of dopamine. Dopamine is a neurotransmitter that affects the arousal center in our brain. The effect is straight away. Secondly, oysters contain high level of zinc, that is important in raising level of testosterone in men. The effect, though, is not immediate.

Arousal for Women
Parsley and truffles may have aphrodisiac potential, as these food smell like that of androsterone, a pheromone usually responsible for men's musky body smell. This smell can influence arousal in women.

More Arousal
Ginger, cayenne pepper and garlic also can stimulate the arousal centers in the brain. Garlic which has anti-clotting properties can affect libido by increasing blood flow to brain and sex organs.

The smooth texture of chocolate and the cocoa's serotonin creating chemical, tryptophan, contributes to chocolate's aphrodisiac potential.


Happy experimenting potentially aphrodisiac foods! Best served with soft dimmed light or maybe during candlelight dinner. Do share stories of your experiences with these food (^-^)

Linking Testosterone and Financial Market Performance

I bet each of you are questioning what's with the title.

This derives from the latest findings from a British study. The study has found that finance desk jockeys with high levels of testosterone are more likely to have a profitable day. The study involves sampling the naturally occurring steroid levels of 17 traders at a big bank in the city of London. The conclusion was that the more testosterone a trader had in the morning, the more money they made for their bank. Thus, the testosterone level may be a biological explanation for the recent twist and turns on global financial markets.

However, the researchers also believe that the downturn may be contributed by another hormone, cortisol, which is a stress hormone. Cortisol responds really strongly if you put an animal or a human in a situation of uncertainty, novelty or uncontrollability. The researchers believe cortisol may cloud the judgement of people in charge.

The big hypothesis is that extreme levels of testosterone exaggerate financial market bubbles, and extreme levels of cortisol exaggerate a financial market crash. Therefore, the testosterone and cortisol levels might be the biological explanation for what happens when the markets become so volatile.

The Right Lifestyle to Improve Chances of Pregnancy

There are several reasons underlying why women are hard to conceive. These include, possibility of a structural problem with the reproductive organs, like blocked fallopian tubes, or a disease of the uterus like fibroids or endometriosis.

Most of the cases are due to a failure of ovulation. The eggs do not ripen and release when they are supposed to, usually caused by a hormonal imbalance. And at older age, our body is not producing enough sex hormones at the right time and in the right amounts to ovulate successfully.

There are good news to couples who are trying to conceive, without having to undergo methods of assisted reporductive technology. In late 2007, the US. Researchers from the Harvard School of Public Health and Harvard Medical School say that adopting a few lifestyle measures can drastically improve the chances of getting pregnant, at any age.

They followed a group of 17,544 married women who were infertile due to ovulation failure but who were trying to get pregnant. The women were part of a larger study of women's health called the Nurses' Health Study II, based at the Brigham and Women's Hospital at Harvard. The researchers followed them over an eight-year period, looking in particular whether or not they followed a range of dietary and lifestyle measures.

They looked at:
- the ratio of mono-unsaturated to trans fats in their diet
- protein consumption (and whether it came from animals or vegetables)
- carbohydrate consumption (including the amount of fibre they ate, and whether high or low glycaemic index)
- consumption of dairy products (and whether low or high-fat)
- iron consumption
- use of vitamin supplements
- body mass index (BMI, i.e. weight in kilograms divided by the square of the height in metres)

- degree of physical activity.

The researchers took into account whether a woman smoked, drank alcohol or coffee, and/or had used oral contraceptives in the past.

Those women with the lowest rate of infertility (and most likely to fall pregnant) were those who ate less trans fat, less sugar, ate food with a low glycaemic index such as pasta and whole grains, ate more protein from vegetables than from animals, had a good iron intake, took multivitamins, exercised daily, kept their BMI between 20 and 25, and (surprisingly) consumed more high-fat dairy products and less low-fat dairy products.

The more of these measures they adopted, the lower the infertility rate and the higher the pregnancy rate. This was regardless of the woman's age, or whether she'd had children before.
For example, those who adopted just five of these measures had a 69 per cent reduced risk of infertility compared to those who adopted none of the measures.

Even following just one of these lifestyle measures reduced the risk of infertility by 30 per cent compared to those women who followed none. Of all the lifestyle measures, weight and diet, rather than exercise, were the most important.

These measures improve fertility was believed is to be caused by improved insulin resistance. They help regulate insulin and blood sugar levels and this in turn may help the sex hormones to regulate ovulation successfully.

Why high fat dairy products help remains a mystery though.
Now adopting these measures won't necessarily work for other types of infertility, such as blocked fallopian tubes. But what it does mean is fertility due to ovulation problems, which account for most infertility cases, can be partly prevented through modifications of diet and lifestyle, the authors say.


The researchers also added that these measures are also good for the pregnancy if a woman does conceive. Taking multivitamins containing folic acid helps prevent neural tube defects in the foetus. And keeping weight down reduces the chances of pregnancy complications like gestational diabetes or pre-eclampsia.

Improve Pregnancy Chances of IVF

For those of you who are trying to conceive by undergoing IVF (In vitro fertilization), you can relieved now because there is a way to improve the success rate of IVF.

IVF is a technique in which egg cells are fertilised by sperm outside the woman's womb, that is in vitro. IVF is a major treatment in infertility when other methods of assisted reporductive technology have failed. Though IVF is an option, but it's time consuming, expensive and has a high failure rate. Couples usually need to undergo IVF for several cycles before they succeed.

Now you may want to look at traditional Chinese acupuncture to improve your pregnancy chances. The theories behind it is may be caused by release of hormones which control our menstrual cycle, and relief of stress (oh well, you should ask your Chinese 'sinshe' for futher details).

Researchers have brought together all the trials they could find of needle acupuncture versus pretend acupuncture in women having an embryo transferred as part of IVF, to see what the sum of the evidence might be. Seven trials involving over 1300 women met the strict criteria of inclusion.

When there was active acupuncture, the pregnancy success after embryo transfer was higher. Around nine or 10 women had to have acupuncture for one to fall pregnant or take home a baby. When the researchers looked at studies where the background success rates of IVF were already high, the add-on benefits of acupuncture were less.

The indications show that acupuncture might do the job. But given it is cheap and relatively harmless, it may save you time and money to help falling pregnant.

Pregnancy and Hair Cycle

During pregnancy, does a woman lose her hair, no changes to her hair thickness, or hair grow thicker?
We might all guess that a woman will lose her hair during her pregnancy, like myself and my frens assumed. The correct answer is, a woman's hair grow thicker during pregnancy!

The underlying reason is hormones. Initially, human hair has a life cycle, from growing to falling out (or rather is pushed out by the new hair frowing in the follicle). During pregnancy, this cycle changes.

When a woman is pregnant, oestrogen extends the hair growth cycle. Hair stays in for longer period before falling out. This explains why women in later stages of pregnancy have very thick hair.

But this 'advantage' stops when a woman gives birth. Once a baby is born, the level of oestrogen drops back to normal, and the hair grown during pregnancy stop growing and remain dormant for a few months.

About 3 months after the baby is born, the mom start to lose her extra hair. This usually happens in the same time when the baby starts to play with his/her saliva. Many traditional grandmothers could right away tell that a mom is losing her hair, only by noticing the baby starting to play with his/her saliva.

Hair loss may vary from person to person. But don't be afraid, as hair loss only lasts for a few months. Hair growth should be back to normal 12 months after birth. So my suggestion is, flaunt it while you have it!!!
