This blew me away. And if true - how cool would that be.

It is said that the sperm carrying the Y chromosome uses energy faster than the sperm carrying the X chromosome. The energy utilization is said to be due to the speed in which sperm swim. Supposedly, the Y sperm is speedy or contains less mitochondria whereas the X sperm is slower or carries more mitochondria. Mitochondria are the energy producing cellular components which are absolutely necessary for life.

Sperm contain, and can only produce, so much fuel for their journey. If one sperm type swims faster than another, the consequence of that, of course, is faster arrival - but also faster expiration.

That said, if a woman knows her cycle and when she ovulates, the odds of baby gender prediction can be in one’s favor.

Sperm can reach the fallopian tubes in about 20 minutes to 2 hours. Sperm are viable for about 4-7 days inside the woman. [This is dependent upon numerous factors - one main factor being the consistency of her cervical fluid.]

Given that the sperm carrying the X chromosome lives longer, then it is possible to gender predict.

How??

Let’s give an example of how this baby gender prediction or sex determination would work.

You want - a girl.

You know Sue ovulates 15 days into her cycle. You know you must deliver sperm no earlier than 4 days before ovulation. This way, the Y carrying sperm will likely be expired and the X carrying sperm still viable. When the egg is released at about 5 days after intercourse, the X carrying sperm will be in the fallopian tube waiting. Mrs. X chromosome sperm touches the egg and a little girl has begun!

The critical and perhaps not so obvious tip - don’t repeat intercourse again for a week! Make sure she has been fertilized with the ‘mature sperm’

To sum up:

If you want a girl - aim for earlier intercourse before ovulation - at least 4 days before she ovulates.

If you want a boy - aim for later intercourse before ovulation - say about 1 day before she ovulates.

Does older sperm mean less healthy? This is not known; however, it is not the genetic material that dies right away. It is the motility or movement of the sperm which is limited and also the fuel stores.

How do you know when Sue ovulates? She charts her cycle by temperature. In the morning, she takes her temperature before even getting out of bed. No alcohol use the night before or erratic schedule - like staying up till all hours. Recording the temperature will show normal slight variation of about +/- 0.2 points. When there is a ’spike’ in temperature she has ovulated. The upward spike is typically about 0.4-0.6 points of a degree. It will stay steady for a bit and then drop off gradually. If the temperature doesn’t drop off, she is pregnant!

Now is this baby gender prediction scientifically proven? I am not sure but I doubt it. The viability of sperm is proven. The difference of speed and viability of x vs y chromosomes is proven. So the information presented here is postulated and assumed based on that data.

Why not give it a shot? Baby gender prediction can only be fun! And if it works - how cool would that be?

We need to research this. Seriously. I wouldn’t think it would be that hard of a study to do. Anyone want to try it and let me know how it turns out?

In health,

Unless your practitioner gives you specific restrictions or instructions, you should keep active during pregnancy. This may be as simple as walking every day to get your heart rate moving, or it may be a complete fitness program designed to be safe during pregnancy. But you also need to do so safely.

Exercise and fitness are activities you can control. They are important in pregnancy, just as they are during every other time of life. We all feel better when we’re active, and this alone can make your pregnancy more enjoyable. Exercise will likely improve your mood and help you enjoy the weeks as they fly by. It also may help you be better prepared for the rigors of labor and improve your ability to reach inside of yourself when that little bit extra is called for. Here are some guidelines for safe exercise:

• Keep your heart rate moderate. Try to keep your peak pulse rate below 140. Above this level your body may begin to divert blood away from the uterus and your baby. This is probably not significant until the third trimester, but it’s still a good rule to follow. You can get a heart rate monitor at any sporting goods store or just use this rule of thumb: you should be able to carry on a conversation while you exercise.
• Stay hydrated. Always drink lots of fluids when you work out. Dehydration can cause dizziness, a tendency to faint, a drop in blood pressure, increased heart rate, and pre-term contractions.
• Don’t strain your back. Avoid any lifting using your lower back. Whether it’s a twenty-pound weight or a piece of paper you’re picking up, you should always lift with your knees instead of your back. That’s important because your lower back is already stressed due to your growing midsection. Also, placental hormones cause relaxation of the ligaments, which is good for labor but also makes it easier to pull or strain body parts.
• Avoid jarring exercises. This is most relevant in the later months, but step classes or jogging may have too much impact. Spin classes, fast walking, and supervised weight training are all safe in pregnancy. Possibly the best exercise for a pregnant woman is a swimming or pool training class, since the strain on your ligaments and back is virtually eliminated.

Common sense is one of the best gauges as to what you can do while pregnant. Certainly, walking, swimming, jogging (in the first few months), light weightlifting, and yoga are all great for you and your baby.

‘When is the best time to get pregnant?’ is a question that our web site visitors ask again and again.
The answer is simple, at the time of ovulation.
Becoming pregnant however isn’t simply a matter of depositing sperm in the woman at or around ovulation time. For the sperm and the egg to be fertile and for the male sperm count to be high a certain care of ones body and mind is needed.
Basic care such as healthy eating, * definitely no smoking, no drinking, no drug taking (including prescription drugs if at all possible - consult your doctor), combine this with a generally stress free life and your chances of conception will increase greatly.

*Smoking not only fatally damages the unborn child but also greatly reduces the risks of conception.

To further increase your chances you should be aware that excessive ejaculation greatly reduces the sperm count and therefore also reduces the chances of fertilization. Making love twice a day every day to ensure that at the unknown moment of ovulation there is sperm present is NOT the answer to getting pregnant. The woman’s cycle should be plotted as best as possible and the couple should learn the tell tale signs of ovulation so as to know exactly when ovulation is about to occur. There are many ways of ‘getting to know’ your cycle and body that are outlined in other articles which can be found at http://pregnantfocus.com

Once the couple is aware of the approximate ovulation time, make love once every 2 or 3 days, keep healthy bodies and healthy states of mind and then conception should occur without problems in the majority of couples.
