Study of the effects of a long acting injectable-progesterone on the ovarian and uterine histomorphology of the androgenised female rats of Long-Evans strain.

The study was aimed at determining the possible role of long acting progesterone-DMPA in effecting reversal of the effect of TP on neonatally treated female Long-Evans rats. Five day-old female litters injected with 1.25 mg. TP went into persistent estrous on attaining maturity. DMPA when given in proper dosage and time reverted the condition.
