Is the development and stages of zygote, blastocyst, etc. The same whether or not u have had IVF or the natural way?

Same: Development is the same, the difference is ivf embryos enter the uterine cavity earlier than in natural conception. ...Read more

Blastocyst (Definition)

We use this term for one of the early phases after fertilization, in which the mass of cells produced by the division of the fertilized egg has acquired a central cavity, making it hollow, and one can tell which cells will become ...Read more

Do you believe in destroying a zygote thru abortion?

Do you believe in destroying a zygote thru abortion?

Faith issue: For the religious trained to believe that life begins at fertilization, loss of any fertilized egg or fetus is a killing. A few religions say life begins at implantation - mormons for instance. Many say nothing. If the death of a fertilized egg is abortion, than your diety is the big perpetrator since about 70-85% of ferilized eggs pass out without implantation. None of this is in the bible. ...Read more

What is the definition or description of: zygote?

Merger sperm/egg: The union of sperm cell and egg cell forms a new cell which is called the zygote. This single cell represents the beginning of each of us as a human being. ...Read more

In which location does the formation of a zygote occur?

It depends on how: Early or late in your ovulation cycle the sperm penetrated the ovum. Early on, the fertilization generally occurs in the oviduct, or Fallopian tube, then the zygote travels towards the uterus within the next 48 hours. Spermatozoa can stay viable in the uterus for 72 hours. Thanks for trusting in HealthTap. ...Read more

Do choice advocates believe that the zygote is not yet a human being?

Do choice advocates believe that the zygote is not yet a human being?

Matter of law/ethics: Certainly, all potential that is human is in a zygote. But we have a very long legal history of allowing the needs/rights of one human entity to over-ride those of another. Until a zygote/embryo/fetus can be cared for outside the mother's body, it is, without question, still an extension of her body and therefore subject to her choices about her body. Without choice, her humanity is diminished. ...Read more

What is zygote intrafallopian transfer?

ZIFT: Zygote intrafallopian transfer (zift) is a surgical, laparoscopic, procedure where a zygote is placed in the female's fallopian tube. The zygote continues to grow and migrates to the uterine cavity where it implants. ...Read more

Can being tipsy harm the egg, zygote, or baby?

Can being tipsy harm the egg, zygote, or baby?

Toxic effect: When ethanol is broken down in the body, byproducts including acetaldehyde can have a direct toxic effect on tissue formation. Some are more susceptible than others. The severity alcohol effects correlates directly with the intensity of alcohol exposure. There is no known safe level of alcohol consumption but occasional exposure is common & most kids with that history are fine. ...Read more

Who could benefit from zygote intrafallopian transfer?

Old treament: Zift, or zygote intrafallopian transfer is an old technology that is no longer in use. It is more invasive than routine ivf because it requires abdominal surgery (laparoscopy) and pregnancy rates are lower. ...Read more

What is involved in zygote intrafallopian transfer (zift)?

ZIFT: Zygote intrafallopian trasfer (zift) is a laparoscopic surgical procedure where zygotes are placed in the fallopian tube of the female partner. The zygote will continue to grow and eventually migrate to the endometrial cavity to implant. ...Read more

Where do I go to get a zygote intra fallopian transfer done?

You Don't: No reputable program would offer this technique unless perhaps you were born without a vagina. This was once an option for clinics that demonstrated poor ivf results, but as knowledge improved this is simply a great way to experience ectopic pregnancies and multiple births for twice the cost of normal ivf. ...Read more

Who is not a suitable candidate for zygote intrafallopian transfer?

ZIFT candidate: Embryos live best in the environment of the tubes which act as natural incubators. For women older than 42, ivf may not offer much advantage over the natural cycle. Some studies had shown that placing embryos (zift) or the sperm and eggs (gift) into the distal tubes could yield higher live birth rates than ivf. For most patients, however, ivf is more cost effective than zift or gift. ...Read more

What would happen if the zygote did not implant in the uterus?

What would happen if the zygote did not implant in the uterus?

Passes out: A non-implanted zygote, like the millions of fertilized eggs in normal physiology that do not implant, will either degenerate or pass out and cease to exist. The uterus will remain normal and ready to accept another fertilized egg when the opportunity presents itself. ...Read more

Does thinning of the uterine wall by birth cause the zygote not to attach next time?

Maybe: The uterine wall is designed to stretch and thin out as the pregnancy advances. Once a person has delivered the uterus returns to its ~ normal size and shape. It is rare for the uterine wall to remain thin after a delivery unless someone had a cesarean section where the incision didn't heal as expected. Sometimes in areas of scarring (from prior surgery, placental attachment) egg might not attach. ...Read more

Can you implant a zygote into the uterus?

Can you implant a zygote into the uterus?

Implantation: In vitro fertilization consists of retrieving a woman's egg and fertilizing it in the lab. The resulting zygote is then implanted into the uterus surgically. This is a common technique for infertility. ...Read more

What is a reason for a zygote not implanting in the uterus?

Implantation: Implantation of the zygote require the following to be working together:
1. Intact fallopian tube for the journey back to the endometrium.
2. Adequate endometrial thickness of 7 to 8mm.
3. Adequate level of cytokines, progesterone and estrogen.
4. Intact genetic make of the zygote.
Combination of all the above factors facilitate implantation and lack of the above impede implantation. ...Read more

Does a failed zygote implantation delay the menstrual cycle?

Does a failed zygote implantation delay the menstrual cycle?

Implantation: Theoretically yes, but it wouldn't delay more than 1-2 days without a positive pregnancy test. If a period is late and test negative it's possible, but no way to say for certain. ...Read more

Do consecutive failed zygote implantation affect fertility? My uterus lining will be recovering from a marina coil removal (which thins the u wall out)

Do consecutive failed zygote implantation affect fertility? My uterus lining will be recovering from a marina coil removal (which thins the u wall out)

Fertility recovers: The Mirena (levonorgestrel) releases progestin which thins your uterine lining and makes it unfavorable for implantation. Once the Mirena (levonorgestrel) is removed your lining recovers and your fertility should be back to normal very rapidly. Not getting pregnant the first 2 months after Mirena (levonorgestrel) removal does not affect your future chances, but at 32 you should get pregnant in the first year of trying. See your doctor if not. ...Read more

Can pcos affect the stage of implantation of the fertilized ovum, after the fertilization of ovum implantation can not occur because of pcos factors?

Can pcos affect the stage of implantation of the fertilized ovum, after the fertilization of ovum implantation can not occur because of pcos factors?

Clarify?: Polycystic ovary syndrome has certain effects on the ability to conceive, but I don't believe that extends to altering the stage of implantation of the fertilized ovum. You really should discuss questions like this to a reproductive endocrinologist, I think that would help in your understanding of the physiology and effects of PCOS ...Read more

Can a day 5 blastocyst be transferred in day 7 of my natural cycle through ivf?

Can a day 5 blastocyst be transferred in day 7 of my natural cycle through ivf?

No: The window of implantation appears to close at about noon on day 6 post-retrieval. While there may be occasional pregnancies, the success rate drops significantly. I am not sure why you or your doc would want to transfer on day 7, but it is almost certainly a poor idea. ...Read more

Hi, I had day 5 embryo at blastocyst stage grid bc transfer and today is 5 days pass the transfer I don't any symptoms does this means negative.

Embryo transfer: We presume implantation takes place within 48 - 72 hours of the transfer but you won't detect any pregnancy hormones until 7 - 12 days after the transfer. Therefore you could still be pregnant even if you don't have any symptoms. ...Read more
