Abstract
Purpose of review: Integrating sex-based analyses is becoming a key point in the new recommendations, particularly in nephrology.
Recent findings: Whereas single nephron glomerular filtration rate (GFR) is not different between men and women, male sex is associated, after multiple adjustments, with a higher number of nephrons. However, after indexation to body surface area, measured GFR (mGFR) in healthy potential kidney donors is not different between men and women between 20 and 50 years of age. After 50 years, mGFR decline seems faster in women than in men, which is concordant with the protective role of estrogens on renal function, as demonstrated in animal and some human studies. Conversely, testosterone has a detrimental effect on renal function. Of note, although testosterone has been shown to increase the kidney volume of the remnant kidney after a unilateral nephrectomy in animal models, this may generate deleterious hyperfiltration in the longer term.
Summary: Taken together, these data highlight the impact of sex on GFR, notably through sexual hormones whose receptors are expressed in glomerular cells.
