We evaluated the effect of the methanol extract of Basella alba (MEBa) on testosterone level and fecundity/fertility in
male rats exposed in utero to flutamide - an androgen receptor antagonist. For this purpose, 1.5- and 2.5 -month-old
male rats exposed in utero to flutamide were treated with the MEBa (1 mg kg(-1) ) for 2 and 1 month respectively. Five
days before the end of treatment, rats were housed with females to assess their fecundity/fertility. Thereafter, rats
were sacrificed and blood collected for the quantification of testosterone. Flutamide-exposed male rats showed a
decrease in their ano-genital distance (AGD, P < 0.05) and were infertile. In normal (methylcellulose-exposed)
animals, MEBa provoked an increase in testosterone level in 1.5- (P < 0.008) and 2.5 -month-old rats (P < 0.01)
concomitantly with the improvement in their fecundity by 25%. In flutamide-exposed male rats, MEBa increased
testosterone level in 1.5 -month-old rats (P < 0.001) without any effect on their fecundity; while in 2.5- month-old rats,
MEBa did not affect the testosterone level but improved fecundity (by 25%) and fertility (P < 0.001). This study
demonstrated the positive effect of MEBa to enhance fecundity/fertility in normal male rats and in rats exposed to the
antiandrogen flutamide during their foetal life.
