Conception

Conception is the process of becoming pregnant. Most women ovulate each month this is when an egg is released by the ovaries. For women with a 28-day menstrual cycle, ovulation typically occurs on day 14.

During intercourse the man will ejaculate and sperm will be passed from the testicles via the penis into the woman's vagina. If a sperm meets the egg, fertilisation may occur.

During a male ejaculation, there are anywhere between 60 million and 500 million sperm that have a go at the 'big race'. They cross the collar of the uterus pretty much within ten minutes. Only about 100 to 200 of the 'chosen ones' will arrive at the most strategic place.

The egg can be impregnated for approximately 24 hours from when it leaves the follicle. Once one sperm is successful and penetrates the egg it will lose its tail and it's head will increase in size. This entrance creates activation in the egg and it too begins to enlarge.

If the egg has been fertilised (the process of the sperm fusing with the egg) it will move to the uterus and attach itself to the uterine lining, a process called implantation. The cells are called a zygote. The cells will begin to divide which will lead to the development of an embryo and hopefully produce a baby in nine months time!

Genetics will determine the sex of your baby. Every man and woman constitutes 22 pairs of chromosomes plus one pair that is the difference between them; these are the sexual chromosomes X and Y. Men have the chromosomes pairing of XY and women have the pairing of

    In the male, meiosis precedes sex cell differentiation. A single spermatogonium enters the first meiotic division as a primary spermatocyte. This division produces two secondary spermatocytes, each of which divides to form two haploid spermatids. Each spermatid then differentiates (by a process called spermiogenesis) into a spermatozoon by the elaboration of structural and functional specialisations that enable the sperm to fertilize the egg. Consequently, four haploid sperm result from each diploid spermatogonium. Sperm produced in the testicles are immature and not very motile. As the sperm make their journey through the tightly coiled epididymis, they mature and become motile.…

    When they do, the egg automatically changes to prevent the other sperm from entering by putting up a protective shield which cover the egg right after the sperm has penetrated it. Now comes the process of fertilisation… A new cell starts dividing at a rapid speed when the genetic material from the mother’s egg and father’s sperm are combined. These cells are known as blastocyst. This travels down to the woman’s fallopian tubes, heading to the uterus. The journey itself can take up to three days or more. Nevertheless, this doesn’t mean the woman is pregnant- it’s only when the blastocyst has attached itself on the woman’s uterus and then that then develops into an embryo and a placenta. After a few weeks, the woman will miss her period, which will indicate she’s…

    Traditional or common portrayals of the fertilization process are inaccurately based on what truly happens because of typical stereotypes and biased information of male and female. Male biologists blow off the idea of the egg “controlling” the sperm by trapping it because they feel that it makes males appear less weak in comparison to women in reality. The limitations of Martin’s study yielded to reader’s wondering why there were small, but vital lies told due to chauvinistic…

    Each cell in the human body contains a total of 46 chromosomes, 22 of the pairs are the same for both sexes, but the final pair determines whether the individual is female or male. If the embryo is a female the chromosomal pattern will be XX, but if the embryo is male the chromosomal pattern will be XY. The chromosomal make-up of the sperm that fertilises the egg determines an individual’s sex. If the sperm carries an X chromosome, the embryo will be female, but if the sperm carries a Y chromosome the embryo will be male.…

    The Sperm and the Egg

    This process all starts with the life of a female human being. When a female child is born they are born with all the ova they will ever have throughout their life, which is about 2 million. After about 15-17 years that child is more developed and goes through a stage in their life called puberty. Only about 400, 00 of the 2 million Ova make it through this stage in a women’s life. I was lucky enough to be one of those 400, 00 who made it through. After this stage myself and the remaining ova resided in a thin capsule inside the women’s ovaries called the follicle. When the woman has reached her reproductive years and the ova have reached their full ripened potential they will be released in hopes of fertilization. There are only about 400 ripened ova that typically make it to possible fertilization. This is roughly 1ova per month (Rathus, S. A., Nevid, J.S., & Fichner-Rathus, L 2011) and today is my day, the day I have been planning my whole life. Today is the day Adam and I will embark on a journey to create a life.…

    Foetal development- human life begins with conception. If sexual intercourse takes place while the egg is in the fallopian tube, there is a possibility of conception. Just one sperm may fertilise the egg. Fertilisation means that the genetic material in the egg to start a new life. Pregnancy then begins when a sperm penetrates an egg. One to one and a half days later, the single fertilised egg cell begins to divide. After two or three days there are enough new cells to make the fertilised egg the size of a pin head. This collection of cells travels to the lining of the uterus where is becomes anchored. The developing collection of cells is now called an embryo. After eight weeks, the embryo may have grown to between 3 and 4cm, has a recognisable heartbeat and the beginnings of eyes, ears, a mouth, legs and arms. At this stage the growing organism is called a foetus. During the remaining seven months before birth, the organs continue to develop. By 20 weeks, the foetus will have reached about half the length of the baby at birth. By 32 weeks, the foetus will be about half its birth weight.…

    Pregnancy begins when a sperm penetrates an egg. One to one and a half days later, the single fertilised egg cell begins to divide. After two or three days there are enough new cells to make the fertilised egg the size of a pin head. The embryo then gets attached to the wall of the uterus by a placenta. Then a chemical signal stops the woman from having another menstrual period.
