Sperm x chromosone faster stronger

The ability of Y-chromosome sperm to swim faster than their X-chromosome counterparts may explain why longer attempts at pregnancy result in more boys than girls. For women hoping to conceive boys, there's an upshot to having a hard time getting pregnant. A new study indicates that the longer it takes a woman to conceive, the higher her fastee of having a boy. Researchers say the findings may have something to do with the fact that sperm that make boys swim faster than those that make girls. If the battle of the sexes started at birth, guys would have a slight advantage: One explanation has to do with the chromosomes in sperm. That means sperm that bear a Y chromosome swim faster in viscous liquids. Such a liquid exists at the tip of a woman's cervix in the form fqster a thick mucous. When cervical mucous is excessively thick, it might be hard for any sperm to reach the uterus. Under such Sperm x chromosone faster stronger, Y-chromosome sperm Sperm x chromosone faster stronger have an advantage. And if that's true, reasoned epidemiologist Sperm x chromosone faster stronger Smits at Maastricht University in the Netherlands, then longer conceptions chromoslne lead to a higher percentage of male babies. The team looked into the issue Sperm x chromosone faster stronger collecting data from women around the age of The women who used medical help to get pregnant, such as in vitro fertilization or having semen injected directly into the uterus, bypassing the cervix, had an equal chance of having boys or girls, suggesting that the boys' advantage lay in the ability of Y-chromosome Atlanta hosiery two feet ahead wholesale to zip faster through the cervical goo. The data are "really interesting," says anthropologist John Martin of Arizona State University in Tempe, and...

You are probably thinking of the Shettles Method which is based on the premise that sperm carrying the X and Y chromosomes have different characteristics and that you can influence the reproductive environment to favor one or the other. While there is some controversy surrounding both the credibility and the morality of the method, here's how the theory goes:. It is the sperm that fertilizes the egg that will determine the sex of your baby. Some sperm carry the X-chromosome and some sperm carry the Y-chromosome. If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy. The idea behind the Shettles Method of sex selection is based on the premise that the X and Y chromosome carrying sperm have different characteristics and that under different circumstances either X- or Y-chromosome-carrying sperm will be more likely to fertilize the egg. Based on these premises, according to Shettles, you can time intercourse, choose a sexual position that favors conception of your preferred sex and influence the reproductive environment to increase the likelihood of conceiving your preferred sex. These are the suggestions from Dr. Time intercourse as close to ovulation as possible: The idea is that since the Y-chromosome sperm are faster than the X-chromosome sperm, there will be more Y-chromosome sperm who reach the egg, making it more likely that a Y-chromosome carrying sperm will fertilize the egg. Have intercourse only just at the time of ovulation and just before. Have intercourse that allows for deep penetration. Men avoid tight clothes: Women have an orgasm: According to Shettles, female orgasm increases the alkaline secretions in the vagina that are favorable to the Y-chromosome carrying sperm. Shettles recommends having an orgasm before or at the same time...

The claim is that human sperm has different physical characteristics i. One theory is that sperm that carry the male chromosome are tiny and fragile but very quick, whereas the female sperm are larger and hardier, but rather sluggish. The male sperm are FAST The female sperm are slow and steady and have a longer life span. The X sperm which are the sperm that make females live longer than the Y sperm which are the sperm that make males. However, the Y sperm swim faster, so the chances are equally good that you will get a girl or a boy. A famous method for gender selection is the Shettles Method , which makes use of the. But according to Entrenched misinformation about X and Y sperm The widely held idea that spermatozoa bearing the Y chromosome Y sperm swim faster than those bearing the X chromosome X sperm seems to have originated from Shettles's work in , using phase-contrast microscopy. Reading Shettles's reports in Nature and other peer reviewed journals, many researchers thereafter believed that Y sperm swim faster than X sperm. The finding particularly influenced research on sperm separation. Although several attempts have been made to correct this impression, it was not until the development of computer assisted sperm analysis CASA that reliable observations could be made. So far, researchers have found no morphological differences between human X sperm and Y sperm. Neither mature sperm nor their precursors possess significant morphological differences between X and Y genotypes ;. Questions Tags Users Badges Unanswered. Do sperm that...

Within a year, Megan and her husband had their baby boy. Check out these suggestions from Dr. Have him wear boxers. To keep things cool, ask your partner to wear loose boxers and to avoid hot tubs. Encourage him to drink coffee. Cough medicine contains the ingredient guaifenesin, which can also help thin the mucus membranes in the cervix, she adds. Have sex in positions that allow for deep penetration. Skip missionary position, and try standing sex or doggie-style with rear entry. Have an orgasm when your partner does. Not only do orgasms cause the cervical mucus to become more pliable and alkaline which male sperm like! Have sex close to ovulation. The main principle of the Shettles Method is timing intercourse correctly. If you have sex precisely when you are ovulating, it allows the faster Y chromosome sperm to get to the egg first before they die. Having sex too soon before ovulation only helps the girls, who are slower but live longer and might already be there when the egg makes itself ready for fertilization. Via hormonal injections, the ovaries are able to produce more eggs which are then fertilized with sperm. When they become embryos, scientists take cell samples to determine whether the cells are girls or boys. Having a healthy baby is what really matters which, for some people , does mean pre-determined gender selection. But, as long as you are healthy and fertile, you may as well try some of these boy-boosters.
