Yes, this is the process of IVF with donor eggs.
Yes. However she would need many hormones to support that pregnancy. The older she is and the further in time away from the beginning of menopause, the more difficult.
The definition of a stem cell is not in question - it is a living cell taken from a living human that has the potential to become multiple different types of cells. The controversy is over embryonic stem cells - stem cells extracted from embryos. The removal of these cells causes the embryo to become non-viable and die. Some individuals feel this is acceptable - the embryos are not going to be implanted into a woman's uterus, so they are going to die anyway when they are discarded as medical waste. Further, the embryos are simply potential human life, but only if they are implanted into a uterus and carried through a nine-month pregnancy. At the time the stem cells are collected, the embryo is a potential human life, but does not have the same moral standing as a human adult. The information and potential treatments that can be derived from these tissues may save millions of lives. Other individuals feel this is unacceptable - the harvesting of stem cells causes the embryo to die, thus becomes equated with murder. To these individuals, the embryo is morally the same as an adult human, with the attendant right to life and to not be destroyed involuntarily for medical research.
There are many moons. Also its possible that in the future we will find other planets that will have other moons so it is possible.
The histology of the uterus from inside to outside consists of three layers: Endometrium: The innermost layer composed of simple columnar epithelium with underlying stroma. It undergoes cyclic changes during the menstrual cycle. Myometrium: The middle layer composed of smooth muscle fibers arranged in different directions providing strength and contractility to the uterus. Perimetrium: The outermost layer of the uterus composed of a serosa or adventitia, depending on its location in relation to other organs.
No. Not even close. Fraternal twins result from two eggs fertilized by two sperm at about the same time and being implanted in the uterus together. They are siblings.Not even identical twins, by the way, can be considered as clones, because cloning involves the removal of genetic information from one cell with its transfer to another cell. Identical twins involve splitting, not cloning.
Yes, Tubal ligation only prevents a womans own egg from reaching her own uterus naturally. Her eggs can be retrieved by a physician and fertilized artificially (test tube fertilization)and then implanted in her uterus to obtain a normal pregnancy.A donors egg could also be used. This is of course barring any other medical problems with her reproductive system.
The fallopian tube is on the other side of the uterus in a woman's sex cell.
You can attempt to have the procedure reversed. It is also possible that invetro (having a fertilized egg implanted in the uterus) would work. Other than that adopting or surrogate mothers are 100% effective.
No and no. Sperm doesn't fuse with other sperms.
IT'S CALLED IVF.
Yes. Because the migration of uterine tissue to other parts of the body is a slow process, and it is possible that the endometriosis started forming before the uterus was removed during hysterectomy.
The blood lining of the uterus gradually thickens during a woman's menstrual cycle in order to be prepared to receive the fertilized egg. This lining will shed during the menstrual period if no fertilized egg has implanted.
Yes: via artificial insemination. Another way is to have a pre-harvested egg inseminated outside the uterus and implanted into the uterus. These and other options for women who want to get pregnant but are having difficulty conceiving are available via most upscale fertility clinics and can be discussed with and explained fully by most gynecologists, but they are most often not covered by health insurance plans and can be extremely expensive and sometimes very difficult, taking a lot of hard work and careful planning. But for those who could not conceive any other way, it is often said to be more than worth it.
When the egg in the uterus is not fertilized after a full cycle, the lining of the uterus and the unfertilized egg that was in the uterus are expelled in the period. Anyone on her period is just about guaranteed to not be pregnant. But it is possible for a girl to get pregnant while on her period; while pregnancy is less likely at this time than other times in the cycle, sperm lingers for some time in the uterus, and might last long enough to fertilize the next egg that is released.
Yes. However she would need many hormones to support that pregnancy. The older she is and the further in time away from the beginning of menopause, the more difficult.
A hysterectomy (surgical removal of the uterus) will stop menstruation, but it's a last resort, and not a cure-all for other health problems. (Bleeding and other symptoms are still possible.)
A cow has only one uterus, just like all other mammals
