Oogenesis02:07

Oogenesis

63.9K
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...

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

597
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle.  At puberty, GnRH secretion increases in both frequency and...

Infertility in Females01:28

Infertility in Females

357
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Disorders of the Female Reproductive System

422
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.0K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Ovarian Cycle01:27

Ovarian Cycle

1.5K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Area of Science:

  • Reproductive Endocrinology
  • Immunology
  • Metabolic Health

Background:

  • Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder affecting reproductive-aged individuals.
  • It is linked to anovulation, infertility, and increased risks for metabolic, cardiovascular, and psychological conditions.
  • The underlying pathophysiology of PCOS remains incompletely understood, with evidence suggesting a role for persistent low-grade inflammation and visceral obesity.

Conclusions:

  • Immune system abnormalities are implicated in the pathophysiology of Polycystic Ovary Syndrome (PCOS).
  • Persistent inflammation and altered immune cell function may drive ovulatory dysfunction in PCOS.
  • Further research into immune factors is crucial for understanding and managing PCOS-related reproductive and metabolic complications.
