Background: About 90% of the worldיs contraceptive users are women. This gender-based usage
has occurred due to the emphasis of family planning programs and contraception research. Condom,
vasectomy and withdrawal are the only male contraception devices available with less assurance for
men. For new male contraceptive to have an impact, they must be acceptable to both men and
women, as well as effective. A hormonal method will likely come to the market within the next few
years. It is necessary to use biologically active botanical substances or fertility-regulating agents of
plant origin which are ecofriendly.
Objectives: The epididymis is a site which can be exploited for male contraception without undue
side effects. It was therefore of interest to investigate the effect of biologically active botanical
ecofriendly plants such as Azadirchta Indica (neem) seed alcoholic extract as an efficient and
competent male contraceptive on male mouse epididymis. "
Materials and Methods: In this experimental case control study sixty adult healthy mice divided
into two groups of 40 as the control and 20 as the treated group. The treated group was administered
by Iranian Botanical Azadirachta Indica seed alcoholic extract, cultivated at Dashteh Moghan
(Ardabil province). The seeds was extracted with ethanol then administered first 50 mgikg body
weight /day then 100 mgikg body weight/day orally for 15 days, following WHO guide lines (MB50).
The target organ, epididymis parameters viz. sperm motility, sperm count fertility rate,
Scanning Electron Microscopic (SEM) morphology of spermatozoa and ATPase activity of
epididymis of the two groups were compared.
Results: The 50 mgikg body weight (BW)/day showed no significant change in epididymal sperm
motility, as compare to the control. Therefore the dose was changed to 100 mg/kg BW/day for 15
days . The body and organ weights (epididymis) of the treated animals were not significantly
changed as compare to control group (p>0 .05). The treatment brought about a significant reduction
in fertility rate when normal cycling female mice were mated with treated males (p<0.00 1). Decline
in ATPase activity in caput and cauda epididymis was observed (p
