[Endocrinologic aspects of habitual abortion]
Summary
Disorders in the luteoplacental progesterone shift cause insufficient progesterone secretion, leading to early and late abortions. Progesterone replacement therapy effectively reduces abortion rates without increasing malformations.
Area of Science:
- Reproductive endocrinology
- Obstetrics
- Maternal-fetal medicine
Context:
- Disorders of the luteoplacental progesterone shift are a significant cause of pregnancy loss.
- Endocrinological issues related to ovarian malfunction typically manifest between weeks 5-10 of gestation.
- Distinguishing between early/late corpus luteum graviditatis disorders and relative luteal deficiency is crucial.
Purpose:
- To investigate the role of progesterone insufficiency in early and late abortions.
- To explore the causes of delayed luteoplacental progesterone shift, including trophoblast and placentation disorders.
- To evaluate the efficacy and safety of progesterone replacement therapy in preventing abortion.
Summary:
- Insufficient progesterone secretion due to luteoplacental shift disorders is a primary cause of abortion.
- Delayed shifts result from trophoblast issues and placentation disturbances, leading to low progesterone levels.
- Progesterone therapy during insufficiency significantly lowers abortion rates, with no observed increase in malformations.
Impact:
- Provides evidence for progesterone's critical role in maintaining early and late pregnancy.
- Highlights the importance of timely diagnosis and intervention for luteal phase defects.
- Offers a safe and effective therapeutic strategy to reduce pregnancy loss and improve outcomes.

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...
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...

Hormonal Regulation of the Menstrual Cycle
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 release.

Ovarian Cycle
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 length...
Hormonal Control of the Ovarian Cycle
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...

Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
