Overview of the Reproductive System01:31

Overview of the Reproductive System

1.4K
The reproductive system generates offspring, ensuring the survival of the species. In humans, the reproductive system is complex and involves a variety of organs and hormones that work together to ensure successful reproduction.
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...

Neurotransmitters01:31

Neurotransmitters

958
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.

Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

1.5K
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...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

396
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

281
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

3.4K
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Area of Science:

  • Reproductive biology
  • Endocrinology
  • Human reproduction

Background:

  • The endocannabinoid system (ECS) plays a fundamental role in regulating various stages of human reproduction.
  • It influences sperm and egg function, fertilization, implantation, placental development, and childbirth.

Purpose of the Study:

  • To summarize current knowledge on the ECS's role in human reproduction.
  • To emphasize the necessity of precise ECS regulation for maintaining a physiological pregnancy from implantation to delivery.

Main Methods:

  • Review of existing scientific literature on the endocannabinoid system in reproduction.
  • Analysis of the interplay between enzymes (NAPE-PDL, FAAH), endogenous cannabinoids, and cannabinoid receptors (CB1, CB2).

Main Results:

  • The ECS, through enzymes and receptors, is vital for reproductive organ function and successful pregnancy outcomes.
  • Dysregulation of the ECS is linked to pathological conditions such as implantation failure, embryo development issues, placental dysfunction, and miscarriage.

Conclusions:

  • A well-regulated ECS is indispensable for a healthy pregnancy and timely delivery.
  • Future research may lead to pharmacotherapeutic interventions targeting the ECS for reproductive health.
  • Components of the ECS may serve as potential biomarkers for monitoring pregnancy and childbirth.
