What does amenorrhea mean?

Amenorrhea refers to the absence of menstruation. This condition can occur for various reasons, including hormonal imbalances, stress, significant weight loss or gain, and medical conditions that affect the reproductive system. It is an important term in gynecology and reproductive health, as understanding the absence of menstrual cycles can help identify potential health issues.

The other choices describe different medical conditions or procedures. For instance, the presence of serum protein in urine relates to kidney function and can indicate issues such as nephrotic syndrome. Transabdominal puncture of the amniotic sac refers to an amniocentesis procedure, which is performed during pregnancy to collect amniotic fluid for testing. Improvement of a condition, while a relevant medical term, does not specifically relate to menstruation or reproductive health. Thus, the understanding of amenorrhea is crucial for identifying and addressing women's health concerns effectively.
