Gonadal and Placental Hormones

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...

Teratogenicity

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...

Development of the Sexual Organs in the Embryo and Fetus

Development of the Sexual Organs in the Embryo and Fetus

Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Neurotransmitters

Neurotransmitters

Neurotransmitters are essential chemical messengers within the nervous system, facilitating the communication between neurons. These chemical messengers, varying in function and effect, are critical for sustaining various aspects of neurological health and emotional well-being.

Hormonal Regulation

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Area of Science:

Neuroscience
Endocrinology
Developmental Biology

Background:

Estradiol, a key estrogen, is vital for fetal and newborn brain development.
Estradiol receptors are nuclear transcription factors with membrane actions, crucial for brain development.

Purpose of the Study:

To elucidate the mechanisms and permanent impacts of estradiol on the developing brain.
To highlight the sensitivity of the developing brain to endocrine-disrupting compounds.

Main Methods:

Review of existing literature on estradiol's effects on neuronal and glial cells.
Analysis of cellular endpoints like apoptosis, synaptogenesis, and morphometry.
Examination of molecular signaling pathways involved in estradiol's action.

Main Results:

Estradiol exerts region-specific effects on apoptosis and synaptogenesis.
Estradiol modulates neuronal/glial cross-talk, calcium handling, gene expression, and kinase activity.
Signaling molecules like prostaglandins and glutamate are involved in sex differentiation.

Conclusions:

Estradiol's actions on the developing brain are permanent and regionally specific.
Environmental endocrine disruptors pose a significant risk to brain development.
Further research is needed to fully understand estradiol's complex mechanisms and potential disruptions.
