Conjoined Twins (Definition)

Conjoined twins are identical twins whose bodies are connected to each other, which is a rare phenomenon. Most conjoined twins are stillborn or die shortly after birth. Some surviving conjoined twins can be surgically separated. Conjoined twins develop when a single fertilized egg only partially splits into twin fetuses, or when an egg splits into twins but ...Read more

Are conjoined twins attached at the head considered one person?

Are conjoined twins attached at the head considered one person?

Good one - no.: Although your question has metaphysical attributes, I would say that clearly cephalopagus conjoined twins are two genetically identical individuals fused at the head, but having separate brain anatomy and psyche. ...Read more

Which type of surgeries would be performed to separate conjoined twins?

Which type of surgeries would be performed to separate conjoined twins?

Varies: Depends on the degree and site of joining. It can be as simple as a skin tube with a few vessels in it, to sharing internal organs and fusion of the crest of the skulls. The surgery to separate each in creases in complexity and sometimes would require the sacrifice of one for instance if there were only one brain or one heart. ...Read more

When conjoined twins are separated and survive the surgery do they still have the same average life span as would a baby born un conjoined?

When conjoined twins are separated and survive the surgery do they still have the same average life span as would a baby born un conjoined?

Depends: Often conjoined twins share organs and other structures that are vital for living a normal life. It would depend on how they are conjoined. Generally their life expectancy would be lower and moreso in 1 twin. Please ask your pediatric surgeon for guidance. He/she would be the best to know. All the best with this difficult dilemma. ...Read more

What are siamese twins?

Conjoined twins: The term "Siamese twins" isn't used medically any longer and may be considered a somewhat crude term for conjoined twins who are identical twins who did not fully separate from each other in the very early stages of development during gestation (prior to birth). Identical twins are really natural "clones"-- a single fertilized egg that split early long before birth into two fully separated beings. ...Read more

I have a fraternal twin brother with microdeletion 22q11.2 (velocardiofacial syndrome). What are the chances my children will have the same disorder?

I have a fraternal twin brother with microdeletion 22q11.2 (velocardiofacial syndrome). What are the chances my children will have the same disorder?

Minimal: These odd micro-deletion syndromes are thought to arise as new defects which could be dominantly passed. Unless you carry it, you won't pass it to your kids and they would have the same risk as the general population to acquire it (new). You might benefit from discussing any and all genetic risk issues from both sides of the family with a geneticist. ...Read more

How can I prevent my 3 children from suffering depressive illness like me. Ages twins 10 and 13 yrs.

How can I prevent my 3 children from suffering depressive illness like me. Ages twins 10 and 13 yrs.

Why worry?: There is nothing you can do directly to prevent if it is a genetic illness. Life bangs us all around a bit and if we have the genetics of depression, which by the way require more than one gene, then there's a chance that we will develop it and a chance that it could be recurrent or chronic. Trust that as they get older the treatments will be better and perhaps even a cure will be found. ...Read more

Twin girls, one dies complications of histiocytosis x (dod 1985) other twin has had no evidence. Are her children at risk?

Most likely no...: Langerhans cell histiocytosis is usually not inherited and typically occurs in people with no history of the disorder in their family.
A few families with multiple cases of langerhans cell histiocytosis have been identified, but the inheritance pattern is unknown. ...Read more

What do you suggest if my husband always like the idea to have twins children. Is there really a way to get yourself a twins, or is it just pure luck?

What do you suggest if my husband always like the idea to have twins children. Is there really a way to get yourself a twins, or is it just pure luck?

Not natural ways: There are medications that can cause multiple eggs to ovulate. There is also in-vitro fertilization where you place two embryos in. But there are no natural ways to promote twinning - what you hear and read are a bunch of wives tales - otherwise it is indeed just something that happens. Not always a good thing, though. Much higher risk of premature birth and all the accompanying problems. ...Read more

I have four single children, youngest being 6months old. I'm 25 years old and my husband is 23, I would like to try for twins and how.

Sorry, can't help you: The reason--multiple pregnancies pose an increased risk to both. See the booklet for parents prepared by the American Socienty of Reproductiie Medicine. One startling statistic: "after ultrasound has shown heart movement in twins, spontaneous loss of one of the fetuses occurs in up to 20% of twin pregnancies." plus a much higher serious complication rate. ...Read more

Is it safe to to take generic Clomid (clomiphene) bought offline to try and conceive twins? I have no medical problems and have two children? I am 31 and my husband is 36

Is it safe to to take generic Clomid (clomiphene) bought offline to try and conceive twins? I have no medical problems and have two children? I am 31 and my husband is 36

Clomid (clomiphene): Clomid (clomiphene) is a prescription medication and should be taken under the direction of a physician familiar with the use of this medication.

Since Clomid (clomiphene) has been around for a long time, there are generic forms of this medication that work just fine. It is a stable medication so it can be sent through the mail system and not lose its potency.

When Clomid (clomiphene) is taken, there is an increase risk of having a twin pregnancy. This is estimated at 15 to 25%. As an infertility specialist, I do not intentionally try to establish a twin pregnancy in my patients. Though the majority of twin pregnancies have a good outcome, about 5% of the time they have a very bad outcome. They are born prematurely. If they are born too premature they can die. If they live, they can have complications of prematurity such as cerebral palsy, mental retardation, blindness, or severe lung problems to name a few.

Rarely, Clomid (clomiphene) can result in triplets or more. I have seen this happen in a patient who took Clomid (clomiphene) on her own. It is always a good idea to take prescription medications only under the direction of a physician. ...Read more

Does in veto mostly come out multiples? What's the percent of me getting pregnant with more than one child by going to a fertility clinic. ..I have 2 children already (not twins) my dad is a twin and my mother got pregnant with twins twice but miscarried

Hello.: Hello. There seems to be some variability to the statistics. With Clomid (clomiphene) there is reported to be a 5 to 12 percent chance of twins. With in vitro fertilization (ivf), the odds could increase to 20 to 40 percent, depending on the number of embryos used. However, before fooling around with mother nature, think about what will you will do if your become pregnant with triplets or quads. Take care. ...Read more

Has there ever been a recorded case of conjoined triplets or only ever twins?

Has there ever been a recorded case of conjoined triplets or only ever twins?

Yes: Triplets may represent twins and a singleton or three separate fetuses. Conjoined multiple births have been describe, but usually the conjoined fetuses are monozygotic (identical twins) with other singleton fetuses that in toto make up multiple fetuses in a given gestation.

I had an u/s done at 6 weeks. I thought I was 7. Found out it was twins. Found no heartbeat or flicker. Is it to soon?

Talk w/ Dr: The Dr who did the u/s is the best to ask about the results - that's part of the procedure! If there was anything drastically wrong - even mildly off - they'd probably have told you. But do call to ask all? S you have. Yes, it might be a tiny bit soon in your case. Read here: http://americanpregnancy. Org/while-pregnant/first-trimester/. ...Read more

Faternal twins at my last u/s they where in the t shape now I'm feelings kicks all over are they able to move all around I assumed they would stay t?

Faternal twins at my last u/s they where in the t shape now I'm feelings kicks all over are they able to move all around I assumed they would stay t?

Wrong assumption: When they are small enough they will move around. As they get bigger and take up more space they will inevitably restrict their ability to move around. There growth will be monitored by your OB. There are standard growth curves. Full term for twins is frequently 38 weeks. Best wishes for a successful pregnancy. ...Read more
