Is the development and stages of zygote, blastocyst, etc. The same whether or not u have had IVF or the natural way?
Zygote: Zygote is first. It happens upon fertilization. ...Read more
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
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
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
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
Zift: Not exactly sure. See: http://harvardmagazine. Com/1997/11/f.science. Html ...Read more
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
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

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
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
No: It will not have any effect.Get a more detailed answer ›
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
Implantation: About a week after conception.Get a more detailed answer ›
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
I'm on cephalexin for uti. I'm ttc and just ovulated if im preg can this antibiotic harm the development of the zygote? I've read can cause birth defects
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
Is transvaginal ultrasound contraindicated in your first few days of pregnancy? If u did does it damage the fertilized ovum?
5-6 weeks: It is not possible to see a blastocyst. The very earliest a gestational sac can be seen is 5-6 weeks from the first day of your last period. ...Read more
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

Have you ever heard of someone thawing out day 3 frozen embryos, growing them out to blastocyst, doing pgd, re freezing, then unfreezing for transfer?
