Because unlike the human system, the female opposum has two separate uteri, one just below each ovary.  The forked penis allows sperm to be deposited into each fork of the vagina, thereby reaching both uteri.

Sex is always good.  Make a poster of all the tubes and organs that a sperm travels through or next to on it's way out of the body.\n\nsome help with the diagram here --> http://images.google.com/imgres?imgurl=http://ib.berkeley.edu/courses/ib140/male%2520erection%2520ejaculation_files/image014.jpg&imgrefurl=http://ib.berkeley.edu/courses/ib140/male%2520erection%2520ejaculation.html&h=1088&w=960&sz=86&hl=en&start=4&tbnid=1PYBLzfybcKM6M:&tbnh=150&tbnw=132&prev=/images%3Fq%3Dsperm%2Bpath%26svnum%3D10%26hl%3Den%26lr%3D%26sa%3DG

Plain and simple.  It is called the Pituitary.  A gland iny our brain the produces sex hormones.  A built in function in our brain that drives us towards sex.  Sex promotes procreation.  \n\nOriginal man was a basic as animal. The goal is reproduction.  The strong surive and produce as many as yourself to ensure a part of you lives on.  Our bodies also developed a great sensation towards sex. A greater reinforcer to have sex and reproduce.  Would you want to have sex or reporoduce if it didn't feel good?

The female sexual cycle is a repeating process on average lasting for 28 days.\nIt's purpose is to;\n\n    * release a single mature ovum\n    * prepare the uterine endometrium for implantation\n\nThe cycle can be broken down into a number of phases...\n\nFollicular Phase (10-16 days)\nThe follicular phase corresponds to the proliferative phase of the endometrium.\n\n    * The pituitary gland, located in the middle of the base of the brain, releases two hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH).\n    * These stimulate the ovary and cause follicular growth.\n    * It is during the follicular phase that a cohort of eggs are recruited and begin to develop and mature inside fluid-filled follicle within the ovary.\n    * As these eggs develop fewer and fewer progress until only one remains.\n      At about days 5-7 of cycle the dominant ovarian follicle emerges and vascularity doubles for this follicle.\n    * The developing follicle secretes the hormone estrogen.\n\nOvulatory Phase (36 hours)\n\n    * The ovulatory phase begins when the level of LH surges, causing the follicle to burst and the egg to be released from the ovary.\n    * The fimbria of the fallopian tube sweep over the ovary and wave the egg into the fallopian tube.\n    * There are changes in the cervical mucus, which becomes clear and thin and increases in quantity, helping sperm through the cervical canal.\n\nLuteal Phase (14 days)\nCorresponds to the secretory phase of the endometrium.\n\n    * During the luteal phase, the follicle that produced the egg becomes a functioning gland called the corpus luteum.\n    * The corpus luteum produces oestrogen which continues to promote the proliferative activity in the endometrium and progesterone which prepares the uterus with the thick lining needed for implantation.\n\nIf implantation does not occur then;\n\n    * The ovum passes through the uterus,\n    * The corpus luteum will cease to function on about Day 26 and regress,\n    * There will be a rapid fall in the secretion of estrogen and progesterone,\n    * The endometrium shrinks due to extracellular fluid loss,\n    * The endometrial blood flow decreases with cell death and destruction of blood vessels,\n    * The uterus will then break down and shed its lining,\n\nMenstruation (4 - 5 days)\nMenses\n\n    * The menstrual bleeding as the uterus sheds the endometrium from the previous cycle.\n    * Blood Loss: 20-80 ml (av. 35 ml).\n    * Demise of corpus luteum.\n    * Estrogen and Progesterone withdrawal.

Nature designed most animal bodies to give-receive pleasure so as to keep the reproduction and the karmic wheel going! "NATURE WANTS MORE AND MORE BABIES! Peek sex drive of most organisms is during the peak fertility periods, esp those during puberty and early adulthood when the DNA of the gametes hopefully is not too damaged yet by the various mutagens out there in the environment and before the prospective parents are too old and tired and diseased to take cre of their offspring.

Based on the 2 conditions above, there are 4 functions.\n\nDigestive:\n\n * Production of Bile\n\nBile contains bile salts which help emulsify lipids (fats) into small oil globules.  Remember, Bile does not digest fats.  It 'chops' up fat in to smaller molecules so as to increase the surface area for enzymatic reactions.--> faster\n\n\n\nExcretory:\n\n * Deamination of excess protein (amino acids)\n\nThe toxic amino group is removed, converted to urea and is passed to the kidneys to be excreted.\n\n\n * Breakdown of red blood cells\n\nAlthough most of the breakdown of the RBCs occur in the spleen, products from the RBCs are sent to the liver for storage purposes.\n\n\n* Detoxification\n\nSolid matter are broken down by phagocytosis.  Bio-chemical conversion of soluble substances (e.g. drugs, alcohol) into harmless substances

Generally fertility drugs are used to try to encourage the ovaries to produce ovum. \n\nIVF - fertilisation outside the womans body of an ovum which has been removed from her ovary.\n\nThere are other methods, but I just can't remember exactly what they are right now. Sorry.

The basic functions of blood are: carry oxygen and nutrients to cells; remove waste from tissues; maintain body temperature by carrying heat to all parts; allow communication between organs (e.g. hormone and neurotransmitter transport)

This organ has two main functions.  \n1. functions as an exocrine organ by producing digestive enzymes\n2. functions as an endocrine organ by producing hormones, with insulin being the most important hormone it produces\n\nThe pancreas secretes its digestive enzymes, through a system of ducts into the digestive tract, while it secretes its variety of hormones directly into the bloodstream. \n\nAbnormal pancreatic function can lead to pancreatitis or diabetes mellitus.

Beneficial Dietary Supplements\nVitamin E helps balance hormone production.\n\nZinc aids proper functioning of the reproductive system.\n\nDMG increases oxygen supply to all tissues.\n\nEssential Fatty Acids enhances function of the reproductive organs.\n\nL-Tyrosine lowers stress and elevates mood.\n\nManganese maintains sex hormone production.\n\nDamiana, Ginseng, Sarsaparilla and Saw Palmetto are helpful for female infertility.\n\nMotherwort regulates menstruation. \n\nYou could also call your local health food store. The people are very knowledgeable in alternatives. Don't be afraid to call. I know someone who could not get pregnant. She went to an herbalist and she suggested some herbs and she became pregnant. She also used it all three times she got pregnant!\nGood luck!!
