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

In which location does the formation of a zygote occur?

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 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

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

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 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

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 didnt heal as expected. Sometimes in areas of scarring (from prior surgery, placental attachment) egg might not attach. ...Read more
