Abstract
This study evaluates the effect of aqueous stem bark extract of Anogeissus leiocarpus on the
ovaries and ovarian function through investigating its effect on the histomorphologic changes in
the ovaries using Hematoxylin and eosin for light microscopy, and the associated changes in the
serum levels of estradiol and progestin hormones using the enzyme-linked-immunosorbent assay
(ELISA). Twenty-four young adult Wistar rats were used for the study. The experimental
animals were synchronized using 0.5ml injection of prostaglandin PGF2α to ensure uniformity in
the estrous cycle before extract administration. Four experimental groups were assigned and
received an extract concentration of 600mg/kg, 400mg/kg, and 200mg/kg for groups I, II and III,
while the control group (IV) received distilled water for the period of six (6) weeks respectively.
The extract has no effect on the microscopic slides of the ovaries prepared at the end of the
experiment.There was an increase in the concentration of progesterone in groups II, and group III
following the extract administration. The progesterone level in the orally treated group was 19%
higher, and statistically significant (p< 0.05), and an increase in the level of serum estradiol in
groups II, and III was also observed after extract administration (p< 0.05).These results suggest
that Anogeissus leiocarpus has a potential effect on the ovarian function indirectly via its
inhibitory effect on PDEs; an effect which is established to promotes developmental competence
of mice oocytes retrieved from small antral follicles.
