Conception: Sperm enter vagina in semen & then pass thru cervix, pass thru uterus into fallopian tube containing ovum or egg after ovulation. 1 sperm pierces thru membrane covering ovum & nucleus of sperm fuses with nucleus of ovum. This fertilized ovum now divides from 1 cell to 2 then 4 & so on.Now an embryo, transfers to body of uterus. Stem cells, within embryo divide, now a fetus develop various tissues ...Read more
Does a uterine polyp 3 weeks prior of embryo transfer could cause a healthy blastocyst with no chromosomes abnormalities not to implant?
How does metabolic influences of mitochondria processing of simple sugars during pregnancy effect the development of the corpus callosum in a fetus?
Fetal development: Truth to say, we don't really know what effects the development of the corpus callosum in the fetus. We do know that about 10% of adults do not have a corpus callosum and are essentially normal. Partial absence of the corpus callosum is abnormal and associated with mental retardation. ...Read more

Nope: Some people think that an orgasm of the female can cause the cervix to "dip" into a puddle of semen which could enhance delivery of the sperm to the fallopian tubes. But in your scenario, sperm have already been delivered and one of them has penetrated the egg. Orgasm is unlikely to make any difference.

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 fetal doppler detect womb sounds, maternal heart beat, and umbilical cord (abdomen the size of a 26 week pregnancy) with a pseudo pregnancy. ?
B/c it is foreign.: A newly transplanted organ is still from another body. The immune system recognizes this as foreign because it has slightly or greatly different hla/tissue types in its cells. These are matched as well as possible before transplant, but there are usually some differences as no two peopl;e are alike. Thus, it attacks it and will kill it unless immunosuppression is done by drugs, etc. ...Read more
Is it possible that past hard drug abuse damage the ova (egg cells) in a woman and cause mental retardation or birth defects?
I have been trying: To find information on this, but the information seems to be focusing on maternal use during pregnancy and not before.It is also heavily focused on alcohol and cigarettes, with results showing that the children of women who smoke or drink have decreased attention spans. I believe, however, that your hypothesis is indeed possible. Perhaps one of my colleagues has found some research on this. ...Read more
