Serum AMH and testicular function
REGRESSION
All men were stratified in tertiles according to serum AMH at day 1 and baseline characteristics are presented in Table Characteristics of included men stratified in tertiles according to serum A﻿MH﻿ at day 1Data presented as median (25th, 75th percentiles) unless otherwise is indicated. *Men with low serum AMH had impaired gonadal function compared with men having higher serum AMH. In accordance, serum AMH was positively associated with sperm concentration (Association between markers of Sertoli cell function (serum AMH, ﻿inhibin B, and FSH) and semen quality All analyses are adjusted for age and BMI. β, regression coefficient. Since AMH is a product and FSH a stimulator of Sertoli cells, we evaluated whether a combination of serum AMH and FSH would be superior to either hormone alone. Men with AMH in the lowest tertile and FSH in the highest tertile corresponds to 16% of the cohort, who had a significantly lower sperm production (differences in median; sperm concentration (∆19 million/mL (475%), sperm count (∆70 million (500%), motile sperm count (∆33 million (550%), progressive motile sperm count (∆20 million (500%) and morphologically normal sperm count (∆1.9 million (950%); Characteristics of included men stratified according to serum AMH and FSH at day 1Data presented as median (25th, 75th percentiles) unless otherwise indicated. *
