Doctors, what is the difference between: intrauterine insemination & in vetro fertilization?

Doctors, what is the difference between: intrauterine insemination & in vetro fertilization?

IVF: In-vitro fertilization is the most advanced ART (assisted reproductive technology) for helping women become pregnant. What is unique about ivf is the woman's oocytes (eggs) are removed from her body to be fertilized in the laboratory with male partner's sperm. Resulting embryos are placed back in her uterus a few days later. Insemination means putting sperm in the woman's uterus. Best wishes. ...Read more

Could someone tell me some differences for in vivo and in vitro fertilization?

Could someone tell me some differences for in vivo and in vitro fertilization?

Vitro is in the lab: In vitro fertilization, ivf, means in latin 'in glass', that is, in the laboratory. In vivo is in the body. In ivf, eggs are removed from the ovary with a needle and inseminated in the laboratory. Ivf is a good treatment for blocked fallopian tubes, and works great for simply enhancing fertility. In addition, new technologies for embryo assessment are great for choosing healthy embryos. ...Read more

What are the differences in days 1-4, 5-13, 14, and 15-28 of the menstrual cycle when fertilization occurs? And when it doesn't?

What are the differences in days 1-4, 5-13, 14, and 15-28 of the menstrual cycle when fertilization occurs? And when it doesn't?

Midcycle: Ovulation usually happens at mid cycle, which is about 2 weeks before the onset of the next period. That would be around day 14 with a 28 day cycle. Keep in mind the sperm can live in the cervical mucus for up to 3 days extending the fertile period. ...Read more

What lenght should I suppose to penetrate a woman for her to get fertilize?

What lenght should I suppose to penetrate a woman for her to get fertilize?

Fertilization: Fertilization of an egg depends on many factors, of which length of sperm travel is just one. However, to maximize the chance of fertilization, the sperm should have the least distance to travel as possible. Thus, depositing sperm at the opening of the cervix would be the most highly beneficial. This, however, is difficult to judge during intercourse. Normal penetration usually does just fine. ...Read more

I'm curious, when a due date is given, it infers a date of fertilization, correct?

Yes: Yes it infers or suggests a conception date; but this is only an estimate from working backwards. No one should take that as anything more than a good guess. ...Read more

If I'm not ovulating and I have unprotected sex is it okay if he cums inside me since there is no egg to fertilize ?

If I'm not ovulating and I have unprotected sex is it okay if he cums inside me since there is no egg to fertilize ?

Not necessarily: Sperm can survive up to 6 days, so even though you are not ovulating now, you are at risk if it happens sometime in the next week. It is unlikely that you can be certain that will not happen. Don't take chances unless it will be OK if you get pregnant. ...Read more

Does menstruatio stops immediately if fertilization occured d?

Does menstruatio stops immediately if fertilization occured d?

Immediately: After conception a woman's menstrual period in most instances ceases immediately; there are exceptions, which is why uterine bleeding is no sure sign for not being pregnant. By the same token, missing a period does not automatically mean there is a pregnancy. ...Read more

After fertilization, is there a certain type of discharge? I'm experiencing a different type of discharge.

Non-specific: There is no type of discharge that is specific to fertilization. A pregnancy test 1-2 days before the expected period is the first reliable sign of pregnancy. Good wishes. ...Read more

If i have sex on the 7th will that sperm fertilize the egg before sperm during sex on the 11th?

If  i have sex on the 7th will that sperm fertilize the egg before sperm during sex on the 11th?

Hmmm....: Have never known sperm to be selflessly polite, and swim in place (they can't stand in line), waiting for sperm from an earlier day to go first. However, many sperm from an earlier day would likely have tired out by the time the newer sperm arrived on the scene. But still, nobody knows. If one man, it doesn't matter. If two men, the rule is to separate men by at least TWO weeks. It's a good rule. ...Read more

If there is a chance I could've gotten pregnant while on my period but the period continued, did fertilization occur?

Period: Not all bleeding is your period, so yes it is possible to conceive while bleeding. It sounds like you have irregular cycles and spotting, which makes it even more likely. ...Read more

What is the process of fertilization?

What is the process of fertilization?

Union of sperm/egg: Fertilization is union of the sperm and egg. At fertilization, many sperm bind to the covering of the egg, the zone pellucida. At the zona, sperm become hyperactive, whipping tails back and forth, and literally drill into the egg. Once one sperm enters the egg, the egg immediately closes access to any other sperm. Egg and sperm dna combine, and cell division begins. ...Read more

Where does fertilization take place in females?

Where does fertilization take place in females?

Fallopian tube: The outer end of the fallopian tube "sweeps" the surface of the ovary and sucks up an egg that was released during ovulation. There then has to be sperm present to fertilize the egg. The fertilized egg then travels for about a week into the upper part (fundus) of the uterus (womb), where it implants. On its trip, the fertilized egg keeps doubling in size: 1, 2, 4, 8, 16, 32 cells aso. ...Read more
