As a fertility specialist, I am here to provide you with accurate and helpful information on the topic of gender selection. It's important to note that while there are certain methods and theories that suggest ways to potentially increase the chances of conceiving a baby boy, there is no scientifically proven method that can guarantee a specific gender.

The concept you mentioned is based on the Shettles method, which is a theory proposed by Dr. Landrum Shettles suggesting that male sperm are faster but less resilient, and female sperm are slower but more resilient. According to this theory, timing intercourse closer to ovulation might increase the chances of male sperm reaching the egg first, due to their speed. Conversely, having intercourse several days before ovulation could theoretically allow the slower but more resilient female sperm to survive longer and possibly fertilize the egg.

However, it is crucial to understand that this method is not scientifically proven to be effective. The Shettles method is based on observational studies and not on rigorous scientific evidence. The speed and resilience of sperm do not solely determine the outcome of fertilization, as many other factors come into play, such as the health of the sperm and egg, the woman's reproductive system, and the timing of ovulation.

Moreover, the sex of the baby is determined by the chromosomes from the parents. Males have XY chromosomes, and females have XX chromosomes. A baby boy is conceived when the sperm carrying the Y chromosome fertilizes the egg. The chances of this occurring are naturally 50/50, as each sperm has an equal chance of carrying either an X or a Y chromosome.

In modern fertility treatments, there is a technique called Preimplantation Genetic Diagnosis (PGD), which can be used to select embryos based on gender. This is typically used for medical reasons, such as preventing the transmission of sex-linked genetic disorders. However, the use of PGD for gender selection without a medical indication is controversial and not widely accepted.

In conclusion, while there are various theories and methods that claim to influence the gender of a baby, none can guarantee a specific outcome. It is essential to approach this topic with a scientific and ethical perspective, understanding that the natural process of conception is complex and not entirely within our control.

Because male sperm is the faster of the two, Shettles suggests having intercourse as close to ovulation as possible. If you have sex several days before ovulation, then the less resilient male sperm may die off, leaving more female sperm to fertilise the egg.Oct 28, 2017read more >>
