Ph and boy sperm

Preconceptual sex selection is still a highly debatable process whereby X- and Y-chromosome-bearing spermatozoa are isolated prior to fertilization of the oocyte. The aim of this study was to separate X- and Y-chromosome-bearing spermatozoa using methods based on the viability difference between the X- and Y-chromosome-bearing spermatozoa. A total of 18 experimental semen samples were used, written consent was obtained from all donors and results were analysed in a blinded fashion. Spermatozoa were exposed to different pH values 5. The live and dead cell separation was done through a modified swim-up technique. Changes in the sex-chromosome ratio of samples were established by double-label fluorescent in situ hybridization FISH before and after processing.

Effects of pH on the migration of X and Y sperm

Winners published at: www. So why is the idea of natural gender selection gaining ground? Rosalind Scutt investigates. If one of those sperm finds its way successfully to the egg the egg is neutral, being neither male nor female and circumstances are favourable, that fertilised egg will develop into a foetus and eventually a baby. Whether you get a boy or a girl depends entirely on which type of sperm meets the egg first a male sperm is programmed with the XY chromosomes and a female sperm is programmed with XX chromosomes. However, contrary to this is the idea that a couple can increase their chances of conceiving a particular gender by manipulating two main factors: body chemistry and the time of intercourse. Though unproven, some believe that the manipulation of body chemistry with diet and exercise and other factors like wearing loose knickers to keep sperm cool can skew the environment to better favour a particular sperm male or female.

Boy or Girl — Can You Choose Your Baby’s Gender?

Despite most parents ultimately just wishing for a healthy baby, there are many cultural and social factors that can drive the desire for a baby of a particular sex. The medical technology for sex selection of embryos has existed in Australia for many years, but such an option is only available for medical reasons, such as sex-linked chromosomal disorder. This leaves parents who do have a gender preference looking for natural ways of predetermining the sex of their baby.
