Insights

Management of gonads in androgen insensitivity syndrome (AIS) is shifting. Current evidence suggests gonadectomy can be deferred, preserving hormonal benefits and fertility while respecting patient autonomy in differences of sex development.

Area of Science:

  • Endocrinology
  • Reproductive Medicine
  • Genetics

Background:

  • Historically, gonadectomy was standard for individuals with androgen insensitivity syndrome (AIS) to mitigate malignancy risk.
  • Recent shifts in clinical practice advocate for postponing gonadectomy until late adolescence.
  • This approach is questioned by adolescents and adults with complete AIS.

Purpose of the Study:

  • To review current knowledge on malignancy risk in different subtypes of AIS.
  • To propose a management protocol for gonad retention in AIS.
  • To address patient autonomy and the benefits of endogenous hormones and potential fertility.

Main Methods:

  • Review of recent literature on gonadal malignancy risk in AIS subtypes.
  • Analysis of data supporting risk stratification for gonad management.
  • Consideration of ethical and human rights perspectives on surgical deferral.

Main Results:

  • Testicular germ cell tumors are increasingly recognized as rare in molecularly confirmed AIS, with some studies reporting 0% incidence.
  • Gonadectomy deprives patients of essential endogenous hormones and potential fertility.
  • Risk stratification offers a more nuanced approach to managing gonads in AIS.

Conclusions:

  • Current evidence supports a risk-stratified approach to gonad management in AIS, moving away from routine early gonadectomy.
  • Deferring gonadectomy respects patient autonomy and preserves hormonal function and fertility.
  • Further research and individualized protocols are needed for optimal care in differences of sex development.

Acute Coronary Syndrome V: Nursing Management

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...

Nephrotic Syndrome II : Assessment and Medical Management

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Gonadal and Placental Hormones01:24

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...

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...
