    Other transhumanist themes include space colonization and the possibility of creating superintelligent machines, along with other potential developments that could profoundly alter the human condition.The reproductive systems in human beings become functional (or start functioning) at a definite age called puberty.The female reproductive system has several additional functions: to be the location for joining of the male and female gametes, to protect and nourish the new human during the period of gestation , and to nourish the newborn infant for some time after birth, though lactation and nursing.ANIMAL REPRODUCTION & DEVELOPMENT Dr Ilma • The two earthworms in this picture are mating • Each worm produces both sperm and eggs, which will fertilize – And in a few weeks, new worms will hatch Asexual And Sexual Reproduction • Both occur in the animal kingdom • Asexual reproduction is the creation of new individuals – Whose genes all come from one parent • Sexual reproduction is the creation of offspring – By the fusion of male and female gametes to form a zygote Mechanisms of Asexual Reproduction • Many invertebrates reproduce asexually by fission – The separation of a parent into two or more individuals of approximately the same size Mechanisms of Asexual Reproduction • Budding – In which two new s in patterns of sexual reproduction • Sexual reproduction presents a special problem for certain organisms – That seldom encounter a mate • One solution to this problem is hermaphroditism – In which each individual has both male and female reproductive systems • Another remarkable reproductive pattern is sequential hermaphroditism – In which an individual reverses its sex during its lifetime Fertilization • Fertilization depends on mechanisms that help sperm meet eggs of the same species • The mechanisms of fertilization, the union of egg and sperm – Play an important part in sexual reproduction External Fertilization • Some species have external fertilization, in which – Eggs shed by the female are fertilized by sperm in the external environment Eggs Internal fertilization • Other species have internal fertilization, in which – Sperm are deposited in or near the female reproductive tract, and fertilization occurs within the tract • In either situation, fertilization requires critical timing – Often mediated by environmental cues, pheromones, and/or courtship behavior • Internal fertilization – Requires important behavioral interactions between male and female animals – Requires compatible copulatory organs • The embryos of many terrestrial animals – Develop in eggs that can withstand harsh environments • Instead of secreting a shell around the embryo – Many animals retain the embryo, which develops inside the…It lies in the interval between the crura of the penis.For fertilization to take place, sperm must be present either a couple of days prior to or on the day of ovulation.These are characteristics that distinguish males from females. The haploid egg cell is called the ovum and is surrounded by the Graafian follicle which produces the female hormone called oestrogen. The egg will die in the tube if it is not fertilised. It promotes an interdisciplinary approach to understanding and evaluating the opportunities for enhancing the human condition and the human organism opened up by the advancement of technology. Introduction This essay addresses the moral status of the human embryo.In many ways, asexual reproduction is a better evolutionary strategy: Only one parent is required, and all of that parent's genes are passed on to its progeny. This essay offers possible explanations of this evolutionary paradox.Corona The corona is a rounded projecting border that forms the circumference of the base of the glans.

    The organs associated with the process of reproduction in human males (men) and human females (women) are different, so the reproductive systems in males and females are different which are known as male reproductive system and female reproductive system, respectively.The organs that comprise the male genital system are the testicles, the epididymis, the vas deferens, the seminal vesicles, the ejaculatory duct, the prostate, the bulbourethral glands, the urethra and the penis.The urethra is where urine comes out of the body from the bladder.The parts of the female reproductive tract normally include two ovaries, two uterine tubes (also called fallopian tubes ), a single pear-shaped uterus, and a single vagina.Genetically sperms contain X and Y chromosomes while the ovum contains the X chromosomes alone.Both the male and female reproductive systems are essential for reproduction.What we shall call the Panglossian view maintains that this past record of success gives us good grounds for thinking that evolution (whether biological, memetic, or technological) will continue to lead in desirable directions.It is broken by sexual intercourse or with the use of tampons.Since only one of the Fallopian tubes contains an egg, many sperm travel in the wrong direction. Transhumanism is a loosely defined movement that has developed gradually over the past two decades.

    If you write about other issues to do with human cloning, you may go off topic.You are specifically being asked to discuss the issue of creating human clones to then use their body parts.Preventative checks reduced the birth rate; positive checks increased the death rate. Reproduction — the process by which organisms make more organisms like themselves — is one of the things that set living things apart from nonliving matter.Testosterone, the male sex hormone, is also produced in the testes.So the best way to answer this human cloning essay is probably to look at both sides of the issue as has been done in the model answer.The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system to create a new individual.
