Does malnutrition impair fetal development?

Does malnutrition impair fetal development?

Yes: Malnutrition can definitely impair many parts of fetal development. One example is if there is a lack of folic acid, the fetal nervous system may not properly form. It is very important to be vigilant of nutrition during pregnancy and your doctor will guide you through it. ...Read more

Ivf (Definition)

In vitro fertilization is an assisted reproductive technology. Ivf is a procedure used to treat fertility problems and assist with the conception of a child. During ivf mature eggs are retrieved from the ovaries and fertilized by sperm in a lab. A few days later, the fertilized egg (embryo) or eggs are implanted into the uterus. One cycle of in vitro fertilization ...Read more

Does conventional ivf increase risk of genetic defect of baby conceived?

IVF & genetic defect: There are genetic causes of infertility that could be passed on to the baby. Otherwise I don't think there is enough data to make conclusions - my opinion. ...Read more

Does ultrasounds give fetal age or gestionation age?

Does ultrasounds give fetal age or gestionation age?

Gestational age: Ultrasounds factor in the manner in which we 'date' pregnancies and they are basing analysis of your baby's growth against all babies of the same age. Hope that helps! ...Read more

What assesses fetal lung maturity?

What assesses fetal lung maturity?

Fetal Lung: There are several indications that the fetus is developing normally. The length of the fetus can be determined by an ultrasound. The lungs may be visualized , and the development of any changes in the lung determined within the limitations of the testing. In addition, the developing lung produces surfactant and if the infant is born prematurely, supplemental surfactant may be needed. ...Read more

Are you referring: to fetal lobulation of the kidneys? That is a normal anatomic variant, not related to an in utero twin. ...Read more

Is this normal pregnancy or miscarriage?
report details:
single intrauterine gestational sac seen measuring 2.2 cms,corresponding to 6+ weeks
no fetal

A little early: It sounds like your sonogram showed a very early pregnancy. Since no baby was seen there are two possibilities - too early to see or a miscarriage where the baby did not form. The sonogram will needed to be repeated in 1 -2 weeks to find out which is correct. ...Read more

Does your partner's sperm help fetal development?

Does your partner's sperm help fetal development?

Of course: The sperm is necessary for fertilization. If you are asking if continued sexual activity and exposure to sperm after conception helps fetal development, I am not aware of evidence to this effect. Ask your obstetrician. ...Read more

6w 4d pregnant with fetal pole, yolk sac ...heartbeat detectd...but seems gestational sac is irregular...sign of miscarriage?

6w 4d pregnant with fetal pole, yolk sac ...heartbeat detectd...but seems gestational sac is irregular...sign of miscarriage?

Don't worry: The most important thing is that the fetus has a heartbeat. Did they tell you an actual fetal heart rate? Sometimes the gestational sac looks different. There could be a nearby fibroid or subchorionic hemorrhage. Signs of a miscarriage are uterine cramping and bleeding. If you are not having those symptoms I would not worry about this. The sonogram can be repeated in 1-2 weeks. ...Read more

Anteverted,bulky gravid uterus,single intrauterine gestational sac 2.7 cm gestational age 6 weeks 6 days no fetal pole is this OK?or a miscarriage?

Blighted ovum: A gestational sac without a fetal with a gestational age of almost 7 weeks is most likely a blighted ovum (non development of the fetus). Most likely with result is a miscarriage. If not you may need a D&C. Follow up with your gynecologist in 1-2 weeks. ...Read more

What amount time/days are required for paternal genome and blastocyst development after embryo transfer?

What amount time/days are required for paternal genome and blastocyst development after embryo transfer?

What?: I'm not sure what your question is. 1. If you had a day 3 embryo transfer it will be a blastocyst in 2 days. If you had a day 5 transfer it is already a blastocyst. 2. Paternal genome is working from day one of combination of the two genomes. The dominant genes regardless of maternal or paternal origin take the lead. Sex development is initiated near the 9th week. ...Read more

Does a blighted ovum miscarriage affect future pregnancies?

Does a blighted ovum miscarriage affect future pregnancies?

No.: Most women have at least one miscarriage during their reproductive life. You should have normal fertility and ability to carry a healthy pregnancy to term. Take Folic Acid 1-5 mg daily before conception. ...Read more

Babyaa 7wks 4days visible gestational sac and fetal pole, no yolk sac heartbeat. Babybb 9wks 4days alive. Could ob/gyn and perinatal ob tested early?

Doubtful: Usually when twin pregnancies occur fertilization happens at approximately the same time. The growth should be very consistent with each other. It appears that baby a will not continue to grow. I'm sorry. ...Read more

Will art or IVF (in vitro fertilization) cause any birth defects in the baby?

Will art or IVF (in vitro fertilization) cause any birth defects in the baby?

Not likely.: See recent impactful publcation in the new england journal of medicine [n engl j med. 2012 may 10;366(19):1803-13. Epub 2012 may 5]. The increased risk of birth defects associated with ivf was no longer significant after adjustment for parental factors. The risk of birth defects associated with icsi remained increased after multivariate adjustment. ...Read more

3 MCs no live birth. 2 MCs turner's & trisomy14 in fetus. Parents karyotyping normal. What other genetic tests shld be done. Risk of abnormal child ?

No need extra tests: No need for further tests before pregnancy since the parents chromosomes are normal. For early piece of mind you can consider early non-invasive genetic screening in early pregnancy. ...Read more

10 weeks transvaginal ultrasound baby heartbeat is 183 what about gender of baby?

10 weeks transvaginal ultrasound baby heartbeat is 183 what about gender of baby?

20 weeks for gender: Domea: the gender of the baby is usually seen at the time of your full anatomy scan which is 18-20 weeks. Sometimes it can be seen sooner or sometimes the baby's position and other factors keep us from seeing it even when you are at the right gestational age. The heart rate is not a good predictor of the baby's gender. ...Read more

Single intruterine fundal gestational sac is seen with no detectable  fetal pole development at 7 weeks 4 days will the baby survive looks like 5weeks?

Less likely: So, the first assumption is that the dating is correct. If you are truly 7+4 weeks, there should be both a fetal pole and a heartbeat. But for various reasons you may be only 5-6 weeks so worth repeating ultrasound to make sure ...Read more
