It may be totally illegal (e.g., Italy, Germany, Austria); legal only if anonymous and gratuitous—that is, without any compensation for the egg donor (e.g., France); legal only if non-anonymous and gratuitous (e.g., Canada); legal only if anonymous, but egg donors may be compensated (the compensation is often described as being to offset her inconvenience and expenses) (e.g., Spain, Czech Republic, South Africa, Greece); legal only if non-anonymous, but egg donors may be compensated (e.g., the UK); or legal whether or not it is anonymous, and egg donors may be compensated (e.g., the US). Indication
A need for egg donation may arise for a number of reasons. Infertile couples may resort to egg donation when the female partner cannot have genetic children because her own eggs cannot generate a viable pregnancy, or because they could generate a viable pregnancy but the chances are so low that it is not advisable or not financially feasible to do IVF with her own eggs. This situation is often, but not always based on advanced reproductive age. It can also be due to early onset of menopause, which can occur as early as their 20s. In addition, some women are born without ovaries, while some womens reproductive organs have been damaged or surgically removed due to disease or other circumstances. Another indication would be a genetic disorder on part of the woman that either renders her infertile or would be dangerous for any offspring, problems that can be circumvented by using eggs from another woman.
An adenoma is a benign tumor of epithelial tissue with glandular origin, glandular characteristics, or both. Adenomas can grow from many glandular organs, including the adrenal glands, pituitary gland, thyroid, prostate, and others. Some adenomas grow from epithelial tissue in nonglandular areas but express glandular tissue structure (as can happen in familial polyposis coli). Although adenomas are benign, they should be treated as pre-cancerous. Over time adenomas may transform to become malignant, at which point they are called adenocarcinomas. Most adenomas do not transform. However, even though benign, they have the potential to cause serious health complications by compressing other structures (mass effect) and by producing large amounts of hormones in an unregulated, non-feedback-dependent manner (causing paraneoplastic syndromes). Some adenomas are too small to be seen macroscopically but can still cause clinical symptoms. Histopathology
Adenoma is a benign tumor of glandular tissue, such as the mucosa of stomach, small intestine, and colon, in which tumor cells form glands or gland like structures. In hollow organs (digestive tract), the adenoma grows into the lumen - adenomatous polyp or polypoid adenoma. Depending on the type of the insertion base, adenoma may be pedunculated (lobular head with a long slender stalk) or sessile (broad base). The adenomatous proliferation is characterized by different degrees of cell dysplasia (atypia or loss of normal differentiation of epithelium) irregular cells with hyperchromatic nuclei, stratified or pseudostratified nuclei, nucleolus, decreased mucosecretion, and mitosis. The architecture may be tubular, villous, or tubulo-villous. Basement membrane and muscularis mucosae are intact.
