Gender of a baby is basically determined by the type of  Sperm [male Gametes] that first fertilize the Ovum [egg]. Sperm produced by man are made up of a mixture of both the X and Y sperm and due to their unique characteristics, the sperm are commonly known as ‘Hardy X’ and ‘Speedy Y’ and the ratio is almost invariably 50/50: -

Hardy X

This female-bearing, oval-headed  X-sperm [Gynesperm] are relatively bigger, slower and live much longer. They have far greater staying power against the hazards of the vaginal environment and they can survive up to 5-6 days.

Speedy Y

The male-bearing , round-headed  Y-sperm [Androsperm] are relatively smaller but have a longer tail that make them faster and more agile. However, they do not live long and in most cases, Y-Sperm will die within 2 days.

During a sexual intercourse, some 100 – 300 million sperm are typically ejected into vagina and about 5% will make it to the neck of the womb [Cervix]. It is here sperm get into contact with Cervical Mucus [CM] and a process called capicitation will take place in which the sperm cap [aerosome] is removed. Only when this happened is the sperm capable of penetrating the Ovum, which is waiting suitably emplaced in the Fallopian Tubes. Within 5 -10minutes after ejaculation, the egg may be fertilized by one of the sperm that has survived this incredible journey. Conception takes place in Fallopian Tubes. The successful sperm loses its tail on entering the egg and its head becomes the a second nucleus in the cell, called Pronucleus. It lies alongside  the females Pronucleus for a few hours before they fuse together in fertilization. A mature egg allow only one sperm to penetrate it and then immediately put up a chemical barrier which prevent other sperm from entering ... download GenderLabs™ for more information  

Gender the baby is genetically determined by the chromosome of the sperm and the formula is a straightforward XX for a girl, XY for a boy: -

If a man’s X-sperm fertilizes the Ovum, a girl will be conceived

X Ovum + X-sperm = XX = Girl

If a man’s Y-sperm fertilizes the Ovum, a boy will be conceived

X Ovum + Y-sperm = XY = Boy

How does the presence of Y-chromosome assigns maleness to a developing foetus? In actual fact, the foetus remains in a sexual limbo and waiting to see what sex it will be even 6-7 weeks after fertilization. A fertilized embryo has the potential of becoming either sex as it contains the rudiment of testicles and ovaries. The testes await a chemical signal from the Y-sperm to kick them into action, the male Y-chromosome contains a tiny gene which produce a putative chemical message [arbitrarily called the ‘Testis Determining Factor’]. On receipt of this message , the testes produce a sudden spurt of Progesterone which stimulate the production of penis and scrotum. Thus it is ensured that male sexual characteristics proceed and female development is sternly suppressed ... download GenderLabs™ for more information
