When a foetus is formed, it has 2 sex chromosomes which decide if the foetus will be male or female. XX chromosomes give a female individual and XY chromosomes give a male. Initially, a foetus is bipotential but at about 6 weeks, the chromosomes ´switch on´ and the testes start to develop. As they develop, they release sex specific hormones. The testes release testosterone and the ovaries release oestrogen.
It starts off with a woman producing an egg which happens each month around two weeks after the menstrual period. The egg then travels from the ovary towards the uterus along the fallopian tube. Conception takes place during sexual intercourse. While the egg is in the fallopian tube, a sperm can fertilise it this happens when the man has an orgasm and ejaculates but only one sperm will be able to fertilise the egg. The fertilisation of the egg means that both genetic material from the egg and sperm joins together to give the beginning of a new life.
Hence it is always the male who determines the sex of the child. For the first 7 weeks of development, the external genitalia appears identical in both sexes. Internally, the same two sets of ducts develop in both males and females. After 7 weeks the differentiation between the sexes begin. The presence of the Y chromosome induces the developing gonads to produce hormones, including testosterone , which stimulate the development of the male internal reproductive system.

Human life begins with conception. A fertile woman produces an egg cell each month two weeks after the last menstrual period. The egg cell travels from the ovary along the fallopian tube towards the uterus. If sexual intercourse takes place while the egg is in the fallopian tube, there is a possibility of conception. Fertilisation is when the genetic material in the sperm joins with the genetic material in the ovum to start a new life.
Summary “Biology Does Matter: Intersexuality, Gender Reassignment Surgery, and Psychological Trauma” is an article written by biological science major, Allison Brown. The introduction starts off by providing information that explains intersexuality, and the procedure involved in reassigning babies as male or female. A famous study known as the “John/Joan” case is introduced, which describes how a newborn genetic male was reassigned female at 17 months of age, and later, at the age of 14, rejected his gender and received reversal surgery to match his genetic sex, male. The article proceeds by explaining in greater detail the process of newborns becoming male or female, followed by the effects of gender reassignment surgery on a child such as depression or having psychological damage later on. Continuing with information about gender reassignment surgery, the article provides a quote from a 1996 policy regarding intersex children, as well as arguments and opinions of professors studying sexuality.
How can we say it is a fetus when everything that makes us original from every other life on earth is implanted within 1 hour? Most abortions occur after or at 9 weeks after conception. A baby has a steady heartbeat 4 weeks after conception. At 9 weeks, this baby has every internal organ it needs to survive. Some people will fight for animal rights, arguing that they should be treated fairly and not killed.
Abortion Should Remain a Woman’s Right According to the Centers for Disease Control (CDC),“In 2010 more than 765,000 legally induced abortions were performed and reported from 49 reporting areas for women ages 15-44, with the majority of abortions performed on women in their 20s” (Abortion Surveillance, 2014). Proponents, or supporters of abortion, believe that it should be a woman’s choice to choose whether or not she wants to bear a child. Those who are
Gender is socially constructed, which doesn’t necessarily signify that females and males are the same nor does their culture makes them different. But, the reason might possibly be that features affiliated with masculinity and femininity is different. In her essay “The Egg and the Sperm: How science has constructed a romance based on stereotypical male-female roles,” Emily Martin argues that the way in which sperm and egg cells
