Treatment | Why? | How? | What? | Pros | Cons | Ovulation induction(OI) | OI is used when the female fails to ovulate this may be due to different reasons. | Ovulation is stimulated by FSH and LH. OI treatment synthetically provides FSH and LH if the OI is caused by a direct problem with the ovary then OI can not be used as treatment. | 1. Clomiphene-increases FSH levels stimulates the P.gland 2. Gondatrophin given by injection increases LH and FSH levels | 1. Possibility of fertilisation

sperm in a dish in a laboratory. Once fertilization has occurred‚ the resulting embryos develop for 3 to 5 days before being placed in your uterus. * Intracytoplasmic sperm injection (ICSI): One of your partner’s sperm is placed inside your egg with a microscopic needle‚ rather than many sperm positioned close to the outside of the egg‚ as in IVF‚ in a dish in a lab. Once fertilization occurs‚ the resulting embryo is placed in your uterus. * Gamete intrafallopian transfer (GIFT): Your eggs

Cloning What is cloning? The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. The copied material‚ which has the same genetic make-up as the original‚ is referred to as a clone. Researchers have cloned a wide range of biological materials‚ including genes‚ cells‚ tissues and even entire organisms‚ such as a sheep. Do clones ever occur naturally? Yes. In nature‚ some plants and single-celled organisms‚ such as bacteria

Drop: Rainwater Harvesting In India By Jessica Canfield‚ Assistant Professor‚ Landscape Architecture/Regional and Community Planning ABSTRACT Only recently has rainwater harvesting begun to gain momentum as a viable‚ sustainable practice within the United States. However‚ in India‚ where economic resources are limited and where the health and survival of the population ultimately depend on rainwater from seasonal monsoons‚ citizens have been harvesting rain since antiquity. Harvesting is now prevalent

being or animal. There is a plethora of controversy about when life truly starts. Does it start right when the sperm meets the egg? Does it start when the fetus develops enough to feel? Most have their own opinion on this topic‚ but if “killing” an embryo can save lives it might be worth it. General stem cell research has been going on for many years‚ but due to cut funding‚ advancements have been inhibited. It was cut because embryonic stem cells research is considered unethical‚ but embryonic stem

According to embryology‚ all vertebrate embryos follow a common developmental path due to their common ancestry. All have a set of very similar genes that define their basic body plan. As they grow‚ the differences that will distinguish the embryos as adults become more and more apparent. The study of this development can yield insights into the process of evolution. This branch of embryology that compares and contrasts embryos from different species is called Comparative Embryology

The top side of the eggs‚ where the embryo resides‚ is marked by marker since the embryo resists rotation to a certain extent. 3. The egg is held horizontally with the marker mark on top and cracked on the edge of an 80 mm triangular magnetic stir bar laying oriented perpendicular to the long axis of the egg

Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden‚ water for livestock‚ water for irrigation‚ and indoor heating for houses etc.. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation. Contents • Advantages • Quality • System setup • Vendors • Rain water harvesting

stem cells is essentially from embryos‚ which are destroyed so the cells are taken from them. A large number of those who do oppose the research believe that the use of embryos is murder‚ since many religions such as the Catholic Church‚ believe that the embryo has a soul and so the use of embryos for stem cell research is considered murder and a sin.

The ban would only be harmful to scientists’ intent on using embryos for research. The ban of all cloning in the medical field would be beneficial to investors who would save millions of dollars on a risky investment. If the proponents were legally allowed to continue therapeutic cloning for research and other medical
