Summary
Hormonal contraception use rose from 35% to 39% in Danish women over a decade. Hormone-intrauterine devices (IUDs) are replacing combined oral contraceptives (COCs), especially in older age groups.
Area of Science:
- Reproductive Health
- Pharmacovigilance
- Public Health Trends
Background:
- Hormonal contraception (HC) has been widely used for 60 years, with extensive research on its effects.
- Understanding current trends in HC use is crucial for public health initiatives.
- This study analyzes recent shifts in HC product selection among Danish women.
Purpose of the Study:
- To analyze trends in the use of different types of hormonal contraception (HC) in Danish women over the past decade.
- To examine these trends across various age groups.
- To identify reasons behind any observed changes in HC utilization.
Main Methods:
- Utilized individual-level HC sales statistics from the National Registry of Medicinal Products.
- Calculated usage in defined daily doses per 1,000 women per day.
- Analyzed absolute numbers and user distributions to identify trends.
Main Results:
- Overall HC use increased from 35% to 39% among women aged 15-49.
- Second-generation combined oral contraceptives (COCs) have largely replaced older generations.
- Hormone-intrauterine devices (IUDs) show a steep increase in use, particularly among women aged 30 and above, replacing COCs.
Conclusions:
- Hormonal contraception use has seen a modest increase, driven by a significant shift towards hormone-IUDs.
- Hormone-IUDs now dominate HC choices for women aged 30 and older.
- These trends are anticipated to lead to substantial reductions in venous thrombosis and menorrhagic complaints.

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

01:22Hormonal Regulation of the Menstrual Cycle
931
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...

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...

01:22Target Cell Response to Hormones
4.2K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

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.

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.
