fertilization of the Xenopus eggs. To begin‚ the female frogs were gently massaged in a manner that was similar to the method of amplexus males use in order to release the eggs. The released eggs were placed in a petri dish where they were to be fertilized by the sperm of a male frog‚ who had donated his life prior to the running of the IVF treatment. In order to fertilize the eggs‚ the testis was diced into a small piece and then was moved around the petri dish touching every egg present in hopes of fertilizing

first of all sexual intercourse in which there is ejaculation of sperms‚ by the male‚ into the female’s reproductive tract. Ejaculation is in form of semen. Sperms travel to fertilize eggs in females. This results in fertilization leading to the development of the baby. Function of reproductive system in females is to produce eggs and to nourish developing offsprings. On the other hand‚ male reproductive system is to produce sperms. Male reproductive system involves organs located inside and outside

Since the live birth of Louise Joy Brown (the first successful ’test-tube’ baby) in 1978; we have heard massive praise‚ accompanied by huge controversy about the use of In-Vitro Fertilization (IVF) and other methods of technology-assisted

in all living organisms. Most ova are unicellular because they are only one cell at first but becomes multi cellular once fertilized by the sperm and begin dividing. However‚ in other organisms‚ such as protists‚ they can start off as multi cellular as well. The ova is the female gamete produced by the female reproductive system and joins together with the sperm‚ the male gamete‚ during fertilization to form the embryo. Gametes are haploids which is the only type of cell that contains only one set

with different sexes. Both gametes produce gametes for fertilisation Sexual reproduction involves the production and fusion of male and femele gametes. In human‚ male gametes called Sperms are produces in the male gomard (reproductive organs) called testes while the famale gametes called ova (singular: ovum) are gametes in the female gonards called ovaries. folio on the contribution of science and technology to human reproduction

process begins with the male producing sperm in the testes and the female producing an egg in the ovaries. Once every 28 days or so‚ an egg matures in the ovary‚ bursts from its follicle and enters the Fallopian tube. Once sexual intercourse has taken place‚ millions of sperm released from the penis swim up the vagina‚ through the uterus and into the Fallopian tube. A single sperm fertilizes the egg; the others are locked out. ’ (Time‚ 1997‚ pg. 66) Once the egg has been fertilized‚ cell division

Brown as she was named brought forth a new hope and era for making babies especially for people who had been diagnosed infertile or sterile. This marked the first time that a human offspring had been created outside the body from the union of an egg and a sperm. The people responsible for this medical breakthrough were Dr. Patrick Steptoe and Dr. Robert Edwards whom had been trying to develop a method to conquer infertility. They were successful with Louise Brown and it has paved the way for many couples
