Characteristics of participants in three cohorts.

<p>For AMH, to convert pmol/L to ng/mL, divide by 7.14.</p

A comparison of Sertoli hormone levels between 3 New Zealand cohorts.

<p>The Otago cohort (205 community dwelling men in Dunedin) is illustrated with brown open circles; the Vascular cohort (153 men in Dunedin selected for their absence of cardiovascular disease) with red open circles and the LiLACS NZ cohort (257 men from a distinct geographical area to Otago) with green open circles. Each circle represents an individual. A: The Vascular cohort had a higher mean AMH value than the aged matched portion of Otago cohort (p&lt;0.001), but were not different to the younger subset (20–50 years), p = 0.35. B: The vascular cohort had similar InhB levels to the aged matched subset of the Otago cohort (p = 0.13), but lower than levels than the younger Otago subset (p&lt;0.001). C: The LiLACS NZ cohort showed similar aged related decline in both A: AMH (p = 0.08) and D: InhB (p = 0.76) when compared to the aged matched subset of the Otago cohort, whilst being different to the younger subset for both hormones, p&lt;0.001 (20–50 years).</p

A cross-sectional study of the AMH levels across the adult lifespan of males.

<p>The levels of serum AMH in 205 community dwelling men (Otago cohort) are illustrated. A: each dot represented an individual. B: the geometric mean and 95% confidence interval is indicated for various age groups. The levels of AMH in the older men (80–93 years) were significantly less than those in the younger men (20–40 years) (p = 0.006). To convert pmol/L of AMH to ng/ml, divide by 7.14.</p

A cross-sectional study of the serum InhB levels across the adult lifespan of males.

<p>The levels of serum InhB in 205 community dwelling men (Otago cohort) are illustrated. A: each dot represented an individual. B: the geometric mean and 95% confidence interval is indicated for various age groups. The levels of Inhibin B in the older men (80–93 years) were significantly less than those in the younger men (20–40 years) (p&lt;0.001).</p

A cross-sectional study of the balance of Sertoli cell hormones across the lifespan of men.

<p>The relationship between AMH and InhB in 205 community dwelling men (Otago cohort) is illustrated. A: The ratio of the hormones across the age spectrum was calculated as described in the Methods. B: Each open circle represents an individual. The linear regression between AMH and Inhibin B was r = 0.48 (p&lt;0.001).</p
