The plant Dracaena arborea (Willd) Linn is a member of the Dracaenaceae family. It grows abundantly in western Nigeria where its leaves are used as traditional herbal treatment for male infertility and as aphrodisiacs and also in the treatment of gonorrhoea, viral ailments like small pox, chicken pox, and measles, epilepsy and stomach troubles. This work was aimed at providing some pharmacognostic standards for the leaf of Dracaena arborea (Willd) and also to provide a scientific rationale for the traditional use of the plant in treatment of male infertility. Standard Pharmacognostic methods were used to conduct microscopic studies of the leaf and also biological activities of the leaves were evaluated. The physicochemical characters such as the ash values, extractive values, moisture content tannins content, swelling index, foaming index, microbial contaminants of the leaf of D. arborea were evaluated according to the methods in the WHO manual (1998). Acute toxicity studies was carried out using the method of Lorke (1983) and the Pro-fertility evaluations for sperm count, motility, viability and abnormal morphology of the methanol extract on male wistar rats was done according to the protocols of Saalu et al (2007) and WHO (1999).The leaf is amphistomatic with anomocytic stomata measuring 36.00 µm in length and 24.20 µm in width with no trichomes. The stomatal number was (10.40-

12.20-14.00) at the upper epidermis and (46.30-54.50-62.70) at the lower epidermis. The stomatal index was (7.80-9.20-10.60) at the lower epidermis and (1.30-1.50-1.70) at the upper epidermis. The palisade ratio was (5.60-6.60-7.60). The powdered leaves had a moisture content of 3.89 ± 0.61 %. The total ash, acid insoluble ash and water soluble ash values were 14.78 ± 0.61 %, 0.53 ± 0.23 %, and 11.22 ± 0.48 % respectively. The alcohol extractive value was 1.13 ± 0.35 % and water extractive value was 1.29 ± 0.13 %.The swelling index was 5.60 ± 0.13 ml and foaming index was less than 100(<100 14="" 4.42="" 6="" aerobic="" and="" aqueous="" bacteria="" cfu="" count="" extract="" for="" fungi.="" in="" methanol="" ml="" of="" plant="" present="" quantity="" relatively="" safe="" span="" tannins="" the="" total="" was="">50 >5000 mg/kg) after oral administration to adult male wistar rats.

1.0              INTRODUCTION
Plants have been used in traditional medicine for thousands of years by humans (Watcho et al., 2009). It is estimated that 80% of the population in developing countries continue to use medicinal plant and plant products in handling primary medical problems due to their accessibility, availability and affordability (Fonge et al., 2012).

Interest in medicinal plants as a re-emerging health aid has been fuelled by the rising costs of prescription drugs in the maintenance of health and the search for new plant-derived drugs as a potential alternative to combat the problems of drug resistance by micro-organisms and as a cheaper and safer alternative to chemical drugs (Soetan and Aiyelaagbe, 2009).

Infertility is a common problem affecting perhaps one in six couples and a large proportion of childless couples are confronted with social stigmatization and personal frustration (Nantia et al., 2009).

Male infertility represents the commonest single defined cause of infertility and amongst the methods used to treat male infertility, medicinal plants have been used. These medicinal plants are used in the treatment of dysfunction of the libido, erection and sperm disorders (Nantia et al., 2009).

A variety of plants are claimed to be used as male fertility enhancers in traditional medicine and biological activities of some of these plants have been shown in some animal and human studies, some of these plants include Sesamum radiatum (Schum. and Thonn.), Cissus populneas L., Tribulus terretris L., Asparagus recemosusWilld., Gingko biloba L., Moringa oleifera Lam., Withania somnifera (L.) Dunal, Mucuna prureins (L.) DC., Lophira lanceolata van Tiegh., Phoenix dactylifera......
