The female sexual cell, or gamete; after fertilization and fusion of the pronuclei it is a zygote; in humans the term egg is not used. In reptiles and birds, the egg is provided with a protective shell, membranes, albumin, and yolk for the nourishment of the embryo.

egg The OVUM or female reproductive cell (GAMETE). The egg contains half the chromosomes required by the new individual, and the other half are supplied by the sperm at the moment of fertilization. The egg is a very large cell, about one tenth of a millimetre in diameter, and much larger than a sperm. This is because it contains nutritive material (yolk) to supply the embryo in its earliest stages before it can establish a supply from the mother via the placenta. If more than one egg is produced and fertilized, a multiple pregnancy results, but the offspring are not identical since half the chromosomes in each come from different sperms, with different genetic material. If a fertilized ovum divides, and each of the two halves forms a new individual, these will be identical twins, with identical chromosomes.

- see OVUM.
- a structure produced by insects, birds and reptiles whose function is to enable embryonic development outside the female on land without the use of water as a growth medium. The vertebrate egg consists of an outer shell (hard in birds, leathery in reptiles), four types of embryonic membranes, a food supply in the yolk sac and surrounding albumen (‘egg white’) and the embryo which develops from an OVUM fertilized before the shell is deposited. Domestic birds can produce unfertilized eggs in which the embryo does not develop.

Patient discussion about egg
Q. Is there any difference between brown eggs and white eggs? My fitness instructor suggested me to have brown eggs instead of white eggs so is there any difference between brown eggs and white eggs?
A. I have to agree with you. Never heard of any difference between the two and it doesnt sound reasonable that one is better to your health than the other...
Q. why the renal doctor told my husband that he needs to eat a dozen of egg a week for protein,how it will help? it won`t afect his cholesterol,also i would like to know what role the protein plays on his treatment and what other foot its rich in protein that he can can take,without causing problems to his health.
A. if i understand correctly, your husband is diabetic. like my grandfather he probably developed a "Diabetic nephropathy" which is a long name to: kidney being destroyed because of blood vessels clotted by diabetes. because of that destruction the kidneys allow protein to go out in the urine. this is a dangerous situation,a protein in the name of "albomin" helps our blood to hold fluids in blood vessels. without it fluid will leave the blood and go to our organs. not a good situation. so he needs a lot of proteins.
here is a list of a 100 protein rich foods:
Q. How can I catch Salmonella? Yesterday I ate a mousse which was made from raw eggs. Could I have caught Salmonella?
A. Salmonella infections usually resolve in 5-7 days and often do not require treatment unless the patient becomes severely dehydrated or the infection spreads from the intestines. Persons with severe diarrhea may require rehydration, often with intravenous fluids (IV). Antibiotics are not usually necessary unless the infection spreads from the intestines.
