Which of the following hormones will most likely increase water retention?

Question

BlackTom AI · Accepted Answer

Question focus: which hormone is most likely to raise water retention?
Option 1: Testosterone. While it influences many cardiovascular and renal processes, it is not primarily associated with promoting water retention. In some contexts testosterone can have diuretic-like effects, so this choice is not the best fit for increased water retention.
Option 2: Luteinising hormone (LH). LH mainly acts on the gonads to stimulate sex steroid production; it does not play a direct or major role in regulating renal water handling or fluid retention, making this option incorrect.
Option 3: Atrial natriuretic peptide (ANP). ANP actually reduces water and sodium reabsorption by the kidneys and promotes diuresis and natriuresis. Therefore, this option would decrease, not increase, water retention.
Option 4: Oestrogen. Estrogen has been associated with increased water retention in several physiological contexts, partly through modulation of the renin–angiotensin–aldosterone system and shifts in fluid balance across membrane channels. This makes water retention more likely when oestrogen levels are elevated.
In summary, among the given hormones, oestrogen is the one most plausibly linked to increased water retention, whereas testosterone and LH do not primarily drive fluid retention, and ANP acts to reduce it. The reasoning aligns with the general understanding of renal fluid regulation and hormonal effects on water balance.
