A fertilized egg outside the uterus should be removed as quickly as possible because the most common outcome of untreated ectopic pregnancy is a burst fallopian tube, which is a medical emergency and in some women leads to infertility.
A fraternal twin set is made when a woman releases two eggs, and each egg is fertilized by its own sperm (unlike identical twins, where one egg splits into two).
A male sperm lives approximately 72 hours inside the woman waiting for an egg to be fertilized.
A tubal pregnancy means that the egg was fertilized inside the fallopian tube and cannot progress to a healthy pregnancy.
A tubal pregnancy occurs more often in women with unaltered tubes when the fertilized egg implants itself in the fallopian tube before reaching the uterus.
Additionally, because eggs can be fertilized for 24 hours after release, the day after ovulation is still considered a fertile time.

Identical twins are formed when one fertilized egg is split into two during the first twelve days after the egg is fertilized.
Identical twins are formed when one fertilized egg splits into two.

In Ephedra helvetica, as described by Jaccard, no proembryo or suspensor is formed; but the most vigorous fertilized egg, after undergoing several divisions, becomes attached to a tissue, termed the columella, which serves the purpose of a primary suspensor; the columella appears to be formed by the lignification of certain cells in the central region of the embryo-sac. At a later stage some of the cells in the upper (micropylar) end of the embryo divide and undergo considerable elongation, serving the purpose of a secondary suspensor.
In fresh-water culture the eggs thus fertilized may be at once distributed to the waters to be stocked, or they may be kept in special receptacles provided with a suitable stream of water until the fry are hatched, and then distributed, or again they may be reared in the hatchery for several months until the fry are active and hardy.
In Naccaria, one of the Gelidiaceae, it is observable that the ooblastema filament, as the tube arising from the fertilized carpogonium has been called, fuses completely with a cell contiguous to the carpogonium before giving rise to the foraging filaments already refered to.
In Peronospora, Saprolegnia, &c., the ends of the branches swell up into sporangia, which develop zoospores in their interior (zoosporangia), or their contents become oospheres, which may be fertilized by the contents of other branches (antheridia) and so form egg-cases (oogonia).

In very rare cases, the tubes can grow back together and an egg can successfully go on to be fertilized.
It is believed that from the nature of the cell in which she is ovipositing, the queen derives a reflex impulse to lay the appropriate egg - fertilized in the queen or worker cell, unfertilized in the drone cell, as previously mentioned.
It is not produced until implantation (when the fertilized egg attaches to the uterine wall).
It is the male element which fertilized the ovule.
It may also prevent an egg from being fertilized or prevent a fertilized egg from implanting in the uterus.
It may be regarded as derived from a wholly dependent sporogonium not unlike that of some of the simpler Bryophyta; the latter are assumed to have arisen from primitive Algal forms, in which, as the first step in the interpolation of the second generation in the life cycle, the fertilized ovum gave rise to a group of swarm spores, each of which developed into a new sexual plant.
It may, however, well be that the capacity for wintering in the dry state has physiologically replaced the need for resistent fertilized eggs.

Of Phanerogams, only the Dryas octopetala covers small areas of the debris, interspersed with isolated Cochlearia, &c., and, where a layer of thinner clay has been deposited in sheltered places, the surface is covered with saxifrages, &c.; and a carpet of mosses allows the arctic willow (Salix polaris) to develop. Where a thin sheet of humus, fertilized by lemmings, has accumulated, a few flowering plants appear, but even so their brilliant flowers spring direct from the soil, concealing the developed leaflets, while their horizontally spread roots grow out of proportion; only the Salix lanata rises to 7 or 8 in., sending out roots I in.
On this view the origin of the sporophyte is looked for in the gradual development of sterile tissue in the generation arising from the fertilized ovum, and a consequent postponement of spore-formation.
Once fertilized, the eggs continue their journey to the uterus where they will implant themselves at regular intervals in the uterine wall.
Only a small proportion of these get fertilized, and still fewer ever emerge from the egg.
Oral contraceptives also change the uterine lining so that a fertilized egg cannot lodge there to develop.
Ovulation is the process in which the female egg travels to the uterus where it can be fertilized by sperm.
Ovulation is the process where the egg leaves the ovary and travels down the fallopian tube to be fertilized by the sperm.

Since the egg can no longer reach the uterus, the chances of it being fertilized are very slim.
Since the egg is unable to travel down the fallopian tubes, they can't make their way to the uterus and they can't get fertilized.
Since the fertilized egg is implanted in an area too small for a growing fetus to survive and it can endanger the life of the mother if the organ where the egg is implanted ruptures, medical care is mandatory.
Since the male's sperm can live up to a week after delivery, breeding as soon as ovulation begins increases the chance that each ripened egg will become fertilized.
So they arranged to produce a number of fertilized embryos which were tested for compatibility with their daughter's DNA.

Suddenly the attraction ceases, and the oosphere is fertilized, probably at that moment, by the entry of a single antherozoid into the substance of the oosphere; a cell-wall is formed thereupon, in some cases in so short an interval as five minutes.
That is to say the animals are fed on what is produced from the fields fertilized with manure.
The Archegoniatae are characterized by a well-marked alternation of gametophyte and sporophyte generations; the former bears the sexual organs which are of characteristic structure and known as antheridia (male) and archegonia (female) respectively; the fertilized egg-cell on germination gives rise to the spore-bearing generation, and the spores on germination give rise directly or indirectly to a second gametophyte.

The doubling process is provided by the act of fertilization, where an antherozoid with the single number of chromosomes fuses with an oosphere also with the single number to provide a fertilized egg with the double number.
The earlier advocates of artificial propagation and fish-hatching seem to have been under the impression that the thousands of fry resulting from a single act of artificial propagation meant a corresponding increase in the numbers of edible fish when once they had been deposited in suitable waters; and also that artificial fertilization ensured a greater proportion of fertilized eggs than the natural process.
The egg consists of a fertilized ovum and a mass of yolk-cells.
The egg consists of an outer casing, or chorion, inside which is the females fertilized ovum.
The egg lives approximately 24 hours and must be fertilized during this time or pregnancy won't occur.
The eggs are fertilized, practically in the ovary, and develop in situ.
The female is fertilized by the male and three or four days later lays a single egg - the winter egg - and then dies.
The female lays two kinds of eggs - " summer-eggs," which develop without fertilization, and " winter-eggs" or resting eggs, which require to be fertilized.

The fertilized egg charged with food reserves rests for a considerable period, surrounded by its cortex, the whole having assumed a reddish-brown colour.
The fertilized egg-cell (oospore) forms a filamentous structure, the proernbryo, from a restricted basal portion of which one or more embryos develop, one only as a rule reaching maturity.
The fertilized ova, provided with yolk and a shell, are next transferred to the "uterus" along which they travel to the exterior.
The filaments arising from the carpogonia grow into long thin tubes, which fuse with special cells rich in protoplasm contents; and from these points issue isolated tufts of sporogenous filaments, several of which may form the product of one fertilized female cell.

The male possesses elaborate copulatory structures of a chitinous nature, and the eggs are fertilized in the female without even quitting the place where they are formed on the wall of the reticular gonocoel.
The offspring of the virgin females are in most of these instances females; but among the bees and wasps parthenogenesis occurs normally and always results in the development of males, the " queen " insect laying either a fertilized or unfertilized egg at will.
The oosphere is in all cases fertilized while still within the oogonium, the antherozoids being admitted by means of a pore.
The ova are fertilized in the genital duct, and before their escape have undergone the earliest stages of segmentation.
The ova pass out of the mouth and are fertilized externally.
The pill contains small amounts of the hormones estrogen and progesterone, which regulate ovulation, thicken the mucus in the cervix, or prevent implantation of the fertilized egg.
The secretion of LH is what causes the most mature follicle in the ovary to burst and release a egg that is ready to be fertilized.
The segmentation of the fertilized nucleus results in the formation of a number of nuclei which arrange themselves around the periphery of the egg and, the protoplasm surrounding them becoming constricted, a blastoderm or layer of cells, enclosing the central yolk, is formed.

The thin-walled eggs are often termed "summer-eggs," the fertilized ones "winter" or "ephippial" eggs (by parity with the phyllopod Entomostraca, q.v.).
Then the fertilized egg must travel to the woman's uterus (womb), where it lodges in the uterus lining and develops into a fetus.
There might not even be one fertilized egg, and even if there were two, pregnancy wasn't guaranteed.
There, the eggs are fertilized and continue to develop.
They are attracted to the flower by its colour or its perfume; they seek, collect or feed on its honey, and while so doing they remove the pollen from the anther and convey it to another flower, there to germinate on the stigma when its tubes travel down the style to the ovary where their contents ultimately fuse with the "oosphere" or immature egg, which becomes in consequence fertilized, and forms a seed which afterwards develops into a new plant (see article Angiosperms).
They enacted the story of his birth and life and death; the Earth, the Mother, is fertilized only by an act of violence by her own child; the representative of the god was probably slain each year by a cruel death, just as the god himself died.
They have two fertilized eggs and they want final consent.
They may also prevent fertilized eggs from implanting in the uterus.
This creates the potential for two separate eggs to be fertilized at the same time.
This ensures that you don't miss the small window of opportunity in which the egg is ready to be fertilized.
This individuality is the result of the particular selection of qualities it receives from its parents, a selection that obviously differs in different cases, as, save in the case of "identical twins," which are supposed to be the product of a single fertilized ovum, no individual pair of brothers, or pair consisting of brother and sister, are alike.
This means that any female flower can be fertilized by pollen from any male.
This phenomenon is usually attributed to the timing of when the fertilized egg was split and may be identified in nearly 25 percent of identical twins.
This remarkable double fertilization as it has been called, although only recently discovered, has been proved to take place in widely-separated families, and both in Monocotyledons and Dicotyledons, and there is every probability that, perhaps with variations, it is the normal process in Angiosperms. After impregnation the fertilized oosphere immediately surrounds itself with a cell-wall and becomes the oospore which by a process of growth forms the embryo of the new plant.
Thus in Erythronium and Limnocharis the fertilized egg may form a mass of tissue on which several embryos are produced.

Tubal pregnancies are caused in instances where something blocks the fertilized egg from implanting in the uterus.
Twins can also result from a fertilized egg that divides slightly later in development.
Very early in pregnancy, vaginal bleeding can be caused by the fertilized egg nesting into the lining of the uterus.
Weismann has also ingeniously argued from the structure of the egg-cell and sperm-cell, and from the way in which, and the period at which, they are derived in the course of the growth of the embryo from the egg - from the fertilized egg-cell - that it is impossible (it would be better to say highly improbable) that an alteration in parental structure could produce any exactly representative change in the substance of the germ or sperm-cells.
Weismann, however, doubts these conclusions, and having found a spermaster in every one of the eggs that he examined from workercells, and in only one out of 272 eggs taken from drone-cells, he supports Dzierzon's view, explaining the single exception mentioned above as a mistake of the queen, she having laid inadvertently this single fertilized egg in a drone instead of in a worker cell.
Wheat is grown year after year without rotation - except in a few cases - on a third or more of our wheat acreage; not one acre in fifty is directly fertilized for the crop, and only a minimum amount of attention is given to the betterment of seed stock.
When a fertilized egg implants itself into the blood lining of the uterus, some women experience mild cramping.
When an egg is fertilized, it travels through the fallopian tubes where it implants into the uterus.
When tubes are cut but remain their original size, the ends can reattach over time, making it possible for an egg to make it down to the uterus where it can be fertilized.
When you figure in the fact that the sperm can survive in the canal for a few days, some eggs could actually have been fertilized a day or more after the final breeding.
When your ovaries release a fertile egg during ovulation, it is typically only available to be fertilized for about one day, or around 12 to 24 hours.
Whether the fertilized egg shall develop into a queen or a worker depends upon the nature of the food.
While thus carried about by the host-insect, the female is fertilized by the free-flying male, and gives birth to a number of tiny triungulin larvae.
With the photos in her hands, the fertilized eggs were a thing of the past.
Without hormones, a normal, healthy woman will release an egg once a month, and her uterus will build up a thick, blood-rich lining to receive the egg in case it gets fertilized by a man's sperm.
