Study area
The study was conducted in Kumasi, (one of the largest metropolitan areas in Ghana and a major trading center) in the Ashanti Region of Ghana. It covers a land area of 254 km2 (98 sq mi) and has a population of 2,069,350 (2013 estimation) forming 36.2% of the total population of the Ashanti Region, the third largest of 16 administrative regions. It has been divided into 10 sun-metro areas namely Batama, Kwadaso, Nhyiaeso, Asokwa, Suame, Tafo, Subin, Manhyia, Asawase and Oforikrom. The city has this geographical location: 6° 40′ 0″ N, 1° 37′ 0″ W. This area was selected for this study because it is a centralized city in Ghana and has people from various tribes and beliefs thus it would provide a varied range of opinion.
Study type and design
A descriptive cross-sectional study on the subject was carried out in retail pharmacies randomly selected across the city.
Sampling technique and sample size determination
The study involved patronage from retail pharmacies. According to the Pharmacy council of Ghana, Ashanti Region office, there are about registered 200 pharmacy outlets within the Kumasi metropolis. Using the modification for the Cochran Formula for sample size calculation in smaller populations, the sample size for pharmacies to be visited was calculated using the formula:

Where “no” is Cochran’s sample size recommendation = 385, N is the population size = 200 medicine outlets in the Kumasi metropolis, and “n” is the new, adjusted sample size.
Thus n = 385/(1+ (384/200)) = 132. To offset possible effects of non-response, 10% of the sample size was added. The total sample size for pharmacies used in this study was 145. Stratified sampling, (a sampling technique in which the population is divided into separate groups and then a probability sample drawn from each group) was then used to select participating pharmacies for the study from the ten sub-metro areas.
Sample population
The study also involved 145 retail pharmacies. A participant from each pharmacy was either Pharmacist or a Pharmacy technician. who had been in practice for not less than 3 years.
Pre-testing of questionnaires (Data collection tool)
A pre-testing of 5 questionnaires for participating pharmacies was done at Oforikrom and Asokwa sub-metropolis to ascertain that the questions were clear and without ambiguity, and that it captures information required for this study appropriately to ensure validity of data (Nyarko-Sampson et al., 2017). After finding the data collection tool appropriate, it was used to carry out the data collection.
Data collection
Structured questionnaire, including both close and open-ended questions on the subject was also designed to collect data from the 145 pharmacy outlets recruited pharmacies. The data collection tool evaluating the type of aphrodisiacs that are frequently purchased, assessing the level of users, determining the level of use of aphrodisiacs, assessing the benefit of its consumption, and ascertaining the side effects present with the use of these drugs, among others.
Data analysis
Data was analyzed using Statistical Package for Social Scientists (SPSS version 20) (SPSS Inc IBM, USA). Graphs were drawn with Sigma Plot version 11 (SYSTAT Software INC, UK). Statistical significance was assessed using the Pearson Chi-Square statistical analysis tool using a 95% confidence interval. P-value ≤ 0.05 shows that there was significant variation between variables compared.
Purchase of aphrodisiacs
Data from the sampled retail pharmacies showed that the rate of purchase of aphrodisiacs from retail outlets is high [104, 70.3%] (Table 1) with the majority of males [56, (38.5%)] who purchased were between the ages of 31 and 45 years (Figure 1).

That notwithstanding, they still prefer to use them, the reason being to satisfy sexual partners and avoid being embarrassed in bed. Among the Pharmacists or Pharmacy technician at the pharmacy retail outlets, 56 (37.8%) said that adverse effects have never been reported to them. For those to which adverse effects have been reported, headache [70, 976.1%)] was the most frequently reported. Poor perfusion, priapism and hypertension were the least reported (3.3%) (Figure 2).
