Tissue (Definition)

The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more

During post strep glomerulonephritis, can it weaken the defence system as well as affect tissue repair ability of the reproductive organs and tissues?

No: The effect is on the kidney and would not have affected other organs. Although once common, this is really a rare complication from a strep infection over the past several decades at least in the US. ...Read more

How do an egg cell and a sperm cell develop into a fetus inside the uterus?

How do an egg cell and a sperm cell develop into a fetus inside the uterus?

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?

Does a uterine  polyp 3 weeks prior of embryo transfer could cause a healthy blastocyst with no chromosomes abnormalities not to implant?

Polyp not good: If we know that someone has an endometrial polyp, we like to remove it prior to an embryo transfer. Miscarriage risk is increased if there are polyps. As expected, pregnancy rates are higher after hysteroscopies and polypectomies. Good luck! ...Read more

How does metabolic influences of mitochondria processing of simple sugars during pregnancy effect the development of the corpus callosum in a fetus?

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

Will orgasm at the time of possible implantation of a fertilized egg affect the process?

Will orgasm at the time of possible implantation of a fertilized egg affect the process?

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. On the the other hand, i don't think it will hurt! ...Read more

Can ascites caused by endometriosis prevent the sperm from fertilizing the egg and the fertilized egg attaching to the uterus?

Can ascites caused by endometriosis prevent the sperm from fertilizing the egg and the fertilized egg attaching to the uterus?

No: Endometriosis is a complex affliction. It can cause infertility by causing mechanical problelms with the fallopian tubes...Ascites will have no direct effect on the process of getting pregnant. ...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 fetal doppler detect womb sounds, maternal heart beat, and umbilical cord (abdomen the size of a 26 week pregnancy) with a pseudo pregnancy. ?

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.  ?

Fetal doppler...: ...Can detect any movement of blood in the body, but with a false pregnancy, all the doppler rhythms should be at the same rate as the woman's heartbeat. Fetal heartbeat tends to be much faster so if you find that, the pregnancy is probably real. ...Read more

Why does the immune system begin to attack a newly transplanted organ?

Why does the immune system begin to attack a newly transplanted organ?

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?

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
