Do IVF babies have low birth weight

The first successful In Vitro Fertilisation (IVF) birth took place in 1978, and since then, approximately 5 million children worldwide have been born through IVF procedures by 2012. The majority of these children are healthy. However, research suggests a slightly increased risk of birth abnormalities (congenital abnormalities) among IVF-conceived kids. For expert guidance, consider reaching out or scheduling an appointment with the World IVF Centre, renowned for its excellence in the field.


Low Birth Weight in IVF Babies:

It's vital to note that the primary risk in IVF is the potential for multiple pregnancies (twins or more) due to transferring more than one embryo. However, advancements in blastocyst culture allow the transfer of fewer embryos with higher success rates. Blastocyst stage occurs around five days post-conception, enhancing embryo and placenta formation.

Genetic Testing's Role in Reducing Abnormalities:

Preimplantation genetic screening (PGS) and preimplantation genetic diagnosis (PGD) offer tools to detect chromosomal or specific genetic conditions in IVF embryos. Identifying and excluding genetically defective embryos can prevent birth abnormalities or failed pregnancies.

Understanding IVF Birth Abnormalities:

Studies on increased congenital defects linked to IVF face methodological constraints. Infertility itself, rather than IVF treatment, might contribute to the risk. Comparing IVF children's abnormalities to those born to infertile couples not receiving treatment, rather than the general population, is crucial for accurate risk assessment.

General Birth Defects and IVF:

IVF-associated birth defect rates are estimated to increase by about 1% compared to the 3-5% in the general fertile population. Studies suggest that infertile couples, irrespective of conception methods, share similar risks of birth abnormalities as those undergoing IVF.

Specifics of ICSI and Birth Abnormalities:

Couples opting for Intracytoplasmic Sperm Injection (ICSI) might have a slightly elevated risk of anomalies, especially with extremely low sperm counts. Recent research indicates ICSI's limited effect on birth abnormalities when sperm counts are relatively normal.

Birth Malformations and Infant Development:

IVF is linked to "Imprinting Disorders," rare conditions from gene expression irregularities during embryo development. IVF-conceived infants generally exhibit normal neonatal growth, with premature birth being a primary cause of developmental issues, mainly in multiple pregnancies.

IVF's Positive Impact:

While a fraction of IVF-conceived children might face issues, most born after IVF lead normal lives. Advances in genetic testing have enhanced early detection of genetic disorders. Couples considering IVF can explore genetic testing options with their doctors to assess suitability.

Impact of Low Birth Weight:

Low birth weight babies might encounter health complications, such as respiratory problems (Respiratory Distress Syndrome), bleeding in the brain (Intraventricular Hemorrhage), heart issues (Patent Ductus Arteriosus), intestinal problems (Necrotizing Enterocolitis), eye ailments (Prematurity Retinopathy), jaundice, infections, requiring specialized care in a hospital's newborn intensive care unit (NICU).

Seeking Expert Advice:

For comprehensive guidance on IVF-related concerns or low birth weight, consulting with the World IVF Centre can provide personalized insights and support tailored to individual needs.

Diabetes Impact on Reproductive Health

Image
Yes, diabetes has been proven to have an impact on your ability to conceive and deliver a healthy child. Diabetes has been shown to have an impact on both men’s and women’s fertility and reproductive health. Diabetes may interfere with hormones, causing implantation and/or pregnancy to be delayed or failed. Diabetes has also been related to sperm and embryo quality issues, as well as DNA damage (genetic mutations and deletions). Diabetes Impact on Reproductive Health  Glucose is the body’s main energy source. Insulin, a glucose-absorbing hormone produced by the pancreas, normally regulates glucose demand and blood glucose levels. When glucose intake is properly controlled, the body’s glucose levels stay within a healthy range. Otherwise, the individual may exhibit signs or symptoms of diabetes or impaired glucose tolerance. Diabetes is a disease that occurs when the pancreas either does not produce enough insulin (Type I diabetes) or does not function correctly (Type II diabetes) (...

Positive effects of IVF on Mental health

Image
  Maintaining a positive outlook can be challenging, especially when faced with difficulties in conceiving. The initial stages of planning for a family are brimming with hope and excitement. Yet, as time passes and the months of trying extend into cycles 5, 6, or beyond, that enthusiasm may dwindle, replaced by worry and doubt about what the future holds. For guidance and support, consider reaching out to the World Infertility and IVF Centre in Delhi NCR. The Role of Positivity in IVF Mental Health: During the trying journey of fertility, sustaining a hopeful mindset is crucial. Holding onto optimism is not just about emotional resilience but can also influence fertility positively. Constant pessimism may amplify stress levels, affecting mental health, relationships, and overall well-being. Heightened stress could even impact the immune system and fertility, as indicated by various studies. Researchers from Emory University found a link between stress and the hypothalamus, a crucia...
