how long after sex does implantation of the egg occur?

it depends on when you ovulate (when the egg comes out of the follicle (ovary)) and when you have sex.  If you ovulate that day and had sex that day it is possible within 48 hours the zygote (what a baby is called from conception to 12 days) implants into the uterus.

there are only about 5 days in a womans cycle when there isn't an egg possibly in her system....this is immediately after the last one is flushed out in the menstral cycle. the bad news is that sperm will last inside of a woman for about 3 days before it dies. so if you have sex on the 3rd day of not having an egg in your system, the sperm will still be alive when your ovary releases an egg and will most likely fertilize within an hour or so of it's release. women's cycles varry monthly so there is no definite way to tell if it is one of theose 5 consecutive days or not.

In humans, most fertilizations occur in the Fallopian tubes. However, sometimes it does happen in the upper uterus. And in other cases -- especially due to pelvic inflammatory disease -- fertilization can occur externally from the reproductive tract, resulting in a seriously ectopic pregnancy.

You ovulate once a month.that time is 12-16 days after your period.that is the best time to get preg.sperm can take up to a week to die.so i guess the best time to do it with as little chance of getting preg would be about 1-2 days after your period.Or 1-2 days before.but really you should always us a condom.STDs and all that stuff.

Meiosis occurs after sexual maturity in both male and females.\nIn males in happens almost all the time after maturity, as males need to produce millions of sperm.\nIn females it happens approximately once a month and happens much more slowly, producing one gamete (egg or oocyte) for use.

Human sperms take about 65 days to completely develop.

it a that time of ur menstrual cycle when the discharged ovary is thrown out of your body....\nthis egg doesnt gets fertilized due to which it dies after comin in the fallopeon tube of the female vagina .\nonce the sperms enter the vagina when the egg is on the wall of fallopeon tube it gets fertilized and a baby is born....\nthis discharge is along with blood ...

The eggs are nourished within the ovaries, and each month one fully matured egg is released. A mature egg has undergone a process of cell division that gives it 23 chromosomes -- just enough to match an equal number of chromosomes from the sperm. Once an egg is released from an ovary, it's pulled into one of the fallopian tubes leading to the uterus. But one of the 20 million to 200 million sperm released by the man has to catch up to that egg soon: If the egg doesn't encounter a healthy sperm, it will perish in 24 to 36 hours. In that case, it disintegrates and flows out with your period. If the egg does get fertilized, it leaves the fallopian tube and travels into the uterus. If everything is in good working order, it will implant there and begin to develop into a baby.

the woman has a body part called ovaries and once a month the egg (ovum) matures(that means it is ready to reproduce) it takes about 3-4 weeks to travel through the fallopian tubeswhich leads to the cervix where the egg is supposed to meet w the sperm if it doesnt get fertalized then it attatches its self to the lining of the uterus whch is blood rich and it comes out along with the blood once a month. sorry if its too complicated hope it helps!!

In humans, the period when ovulation occurs is called the ovulatory phase, and it occupies the fourteenth day of an idealized twenty-eight day menstrual cycle. Because of the variable nature of the menstrual cycle in vivo, however, normal ovulation can occur as early as day 8 or as late as day 20 and beyond. A woman with a particularly short cycle will ovulate earlier while a woman with a long cycle will ovulate later. In humans, concealed ovulation means that the female shows few visible signs of being fertile, compared to most species.(disputed — see talk page) There are evolutionary analyses of how this could evolve in terms of evolutionary game theory.\n\nBefore ovulation, the ovarian follicle will undergo a series of transformations that are necessary for the ovum to survive afterwards. This process is called cumulus expansion. After this is done, a hole called the stigma will form in the follicle, and the ovum will leave the follicle through this hole. It will then enter the fallopian tubes and travel toward the uterus, implanting there 6-12 days later if fertilized, or degrading in the fallopian tubes within 24 hours if not fertilized.\n\nThe ovulatory phase is preceded by the follicular phase, where an immature follicle-encased ovum completes growing, and followed by the luteal phase, where the uterus is prepared to receive the fertilized ovum. The complete process of follicle growth leading up to ovulation is known as folliculogenesis.\n\nScientific investigations like [1] have indicated that the olfactory acuity or the sense of smell is greatest during ovulation in women.\n\n[edit]\nA closer look at the process\nStrictly defined, the ovulatory phase spans the period of hormonal elevation in the menstrual cycle. The process requires a maximum of thirty-six hours to complete, and it is arbitrarily separated into three phases: periovulatory, ovulatory, and postovulatory.\n\n[edit]\nPrerequisite events\n \nHistology of the preovulatory follicleMain page: folliculogenesis\n\nThrough a process that takes approximately 375 days, or thirteen menstrual cycles, a large group of undeveloped primordial follicles dormant in the ovary is grown and progressively weaned into one preovulatory follicle. Histologically, the preovulatory follicle (also called a mature Graffian follicle or mature tertiary follicle) contains an oocyte arrested in prophase of meiosis I surrounded by a layer corona radiata granulosa cells, a layer of mural granulosa cells, a protective basal lamina, and a network of blood-carrying capillary vessels sandwiched between a layer of theca interna and theca externa cells. A large sac of fluid called the antrum predominates in the follicle. A "bridge" of cumulus oophorous granulosa cells (or simply cumulus cells) connects the corona-ovum complex to the mural granulosa cells.\n\nSimply stated, the granulosa cells engage in bidirectional messenging with the theca cells and the oocyte to facilitate follicular function. Research is elucidating the specific factors used in follicular messenging at a rapid pace, but such discussion is beyond the scope of this article.\n\nBy the action of luteinizing hormone (LH), the preovulatory follicle's theca cells secrete androstenedione that is aromatized by mural granulosa cells into estradiol, a type of estrogen. High levels of estrogen have a stimulatory effect on hypothalamus gonadotropin-releasing hormone (GnRH) that in turn stimulates the expression of pituitary LH and follicle stimulating hormone (FSH).\n\nThe building concentrations of LH and FSH marks the beginning of the periovulatory phase.\n\n[edit]\nPeriovulatory phase\nFor ovulation to be successful, the ovum must be supported by both the corona radiata and cumulus oophorous granulosa cells. The latter undergo a period of proliferation and mucification known as cumulus expansion. Mucification refers to the secretion of a hyaluronic acid-rich cocktail that disperses and suspends the cumulus cell networ

no. u guys did nothing.dontworry.and also ovulation period begins abt 10 to 12 days after ur first day of mesuration cycle.

Women don't "lay eggs!"  The womans period flushes everything out so it will be clean in there for the new egg!  So, usually it's right after!  You're not suppost to have sex if you have a yeast infection!  It can mess up the amount of yeast in the mans body.

Unfortunately for women, we can get pregnant at pretty much any time of our cycle. In most species, only around the time of ovulation. However, sperm can survive in the reproductive tract for 7 days!!! So for 7 days before and 7 days after ovulation, we are vulnerable. \n\nCheck out this picture http://www.fertilityplus.org/images/menstrualcycle.jpg\n\nAfter your period, all hormones are low. A new follicle (egg) from your ovary starts to develop, which makes estrogen, which normally keeps LH and FSH low (follicular phase), but if enough estrogen accumulates, it turns LH and FSH on in the brain. FSH is for follicle development in the ovary, LH is for ovulation (ovulation). The corpus luteum secretes progesterone (luteal phase). In the absence of fertilization, the uterine walls break down, causing you to bleed (menstruation).

have you taken a preg. test yet? you could be preg. already. ovulation is 14-15 days after the first day of your periond. so if you are not preg. count 14 days from the 24th.. you should have ovulated nov. 6th or 7th. good luck..

ovulation lasts from 24 to 36 hours during the middle of your cycle. if you are regular, ovulation will on the 14 day (day 1 starting the first day of your period).

That depends on a few factors:\n\n1) Where did the sperm start?  For a sperm, a couple inches can take a while.\n2) Where is the egg?  Did the woman ~just~ ovulate, or is the egg almost to the womb?\n3) How healthy are the sperm?  Has the man ejaculated in the past few days?  Has it been more than 2 weeks?  If left in the testis too long, sperm will deform and lose motility.\n\nThe text book answer is anywhere from 4 hours to 72 hours.  Really, it depends on the above.

Yes, it's possible. The egg might be fertilized and get fixed in one of the oviduct. This has happened to me too. I had 2 options to make sure I wouldn't get pregnant. \n1. Take the so called 'second day' pill in  maximum 72 hours since the sexual contact. But it has some side effects, including unbalancing the hormone level in the body. \n2. If no more than 12 hours passed to to a gynecologist to prescribe you birth control pills.\n\nI for one, chose the second option and I haven't got pregnant. 4 hours had passed. I also tried the first option when I was ovulating (more probably to become pregnant) and I had a period in the following 5 days.\n\nIMPORTANT! these help only if the egg hasn't fixed yet. Anyway, the first step is a visit to the gynecologist.\n*hugs
