Insights

Both paternal and maternal factors influence placental and offspring birth weight. Maternal factors like pre-pregnancy BMI and diabetes are independent predictors for placental weight, while maternal weight gain and smoking impact offspring birth weight.

Area of Science:

  • Reproductive biology
  • Perinatal medicine
  • Human genetics

Background:

  • Placental and offspring birth weight are critical indicators of fetal development and long-term health.
  • Understanding the influence of parental factors on these metrics is crucial for identifying potential interventions.

Purpose of the Study:

  • To investigate the association between parental factors, specifically paternal influences, and the weight of the placenta and offspring.
  • To identify independent predictors of placental and offspring birth weight.

Main Methods:

  • A population-based birth-cohort study involving 2947 singleton births in Drenthe, The Netherlands.
  • Data collection included placental weight, birth weight, and parental information via questionnaires.
  • Statistical analysis employed univariate and multivariate linear regression models.

Main Results:

  • Paternal birth weight and father's body mass index (BMI) were associated with placental and offspring birth weight, but not as independent predictors.
  • Maternal pre-pregnancy BMI, birth weight, and diabetes were identified as independent predictors of placental weight.
  • Maternal weight gain during pregnancy, birth weight, smoking during pregnancy, and diabetes independently predicted offspring birth weight.

Conclusions:

  • Both paternal and maternal factors significantly influence placental and offspring birth weight.
  • Maternal factors play a more prominent role as independent predictors for both placental and offspring birth weight.

Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Parental Care00:55

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Factors Affecting Drug Distribution: Miscellaneous Factors

Drug distribution in the human body is a complex process influenced by various individual factors, including age, pregnancy, obesity, diet, body water composition, pH levels, and specific disease conditions.
Age plays a significant role due to differences in body composition among different age groups. Infants, for instance, have a higher proportion of total body water and lower albumin levels, a protein that binds drugs in the bloodstream. This unique composition in infants enhances the...
Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
