Baccaurea courtallensis is an endemic tree producing wild edible fruits, used by various ethnic communities and local folks of the southern Western Ghats. Fruits of this tree have been used to treat infertility problems in men and women. The aim of study was to investigate the effects of hydro alcoholic extract of B. courtallensis on fertility of male rats. Hydro alcoholic extract of B. courtallensis (HAEBC) contains several secondary metabolites leading to testosterone metabolism and consequently to the improvement of spermatogenesis. The Hydro alcoholic extract of B. courtallensis (HAEBC) improves the male reproductive functions in male rats
