In the world and particularly in Africa, infertility is more than a health problem but a psychosocial problem [1] [2] . Prevalence is very high in sub-Saharan Africa, where one third of the couples would be affected [3] . Males’ responsibility for the couple’s infertility is in 40% - 50% of cases [3] [4] . Substantial progress has been made in the treatment of male infertility in terms of the rapeutic sinetiological research [5] . This contrasts the prevalence of the disease in steadily increasing [6] . In our practice, very few studies have been devoted to male infertility. The aim of this study was to identify clinical, etiological and epidemiological profile of male infertility at the urology department to improve its management.

It was a descriptive cross-sectional study covered over a period of 12 months from 1^st January to 31 December 2012. The Urology department of teaching Hospital Yalgado Ouedraogo has provided a framework study. It covered topics consultant male desire of fatherhood. Were included in the study all men who viewed desire for paternity and having regular sexual intercourse with or without contraception, the same joint for at least 12 months and leading a regular life with their partners. Consent was obtained from the patient for publication. All selected subjects had at least two spaced at least three months sperm balance sheets consist of a semen analysis, spermocytogram and a semen culture. Semen was collected in the laboratory after an abstinence of 3 to 5 days. Collection after masturbation was preferred to the interrupted whenever possible coitus. Semen analysis was performed according to the WHO standards. Hormonal balance sheet included serum follicle stimulating hormone (FSH) and testosterone. The variables studied were related to:

-Socio-demographic characteristics,

-Clinical,

-Semen analysis, spermocytogram, FSH, testosterone and ultrasonography.

The variables were analyzed in terms of frequency and average. No statistical analysis had done for comparisons among groups. The study has been performed with the approval of a medical ethics committee.

During the study period, 3151 patients were admitted at the urology department and 95 male for infertility. The prevalence was 3%. The average age of patients was 36.9 years (SD = 6.8) with extremes of 23 years and 53 years. Almost 74% of patients were less than 41 years (Table 1).

The average age of brides was 28.6 years (SD = 4.9) with extremes of 19 years and 40 years. Officials, merchants and farmers accounted respectively 32%, 25% and 15%. Nearly 90.5% of the patients resided in urban areas. They were monogamous in 96.8% (N = 92) of cases and polygamous in 3.2% of cases. Patients were referred by gynecologists in 77.9% (N = 74) of cases and by general physicians in 17.9% (N = 17) of cases. Only 4.2% (N = 4) of patients were received in consultation by themselves. The average consultation delay was 3 years (SD = 2.1) and ranged from 1 year to 10 years (Figure 1).

The average duration of infertility was 5.8 years (SD = 3.9) and ranged from 1 year to 20 years. The average frequency of sexual intercourse was 2 to 3 times per week in 98.9% of cases. Infertility was primary in 68.4% of cases and secondary in 31.6% of cases. The history of genitourinary infection were noted in 24.2% (N = 23). Six patients reported, had contracted bilharzia urogenital childhood. Patient histories were reported in Table 2.

Two cases of obesity were observed with body mass index of 31.1 kg/m² and 37.5 kg/m². The review found 7 cases (7.4%) of acute prostatitis. Clinical and ultrasonography examination of the scrotal contents found 21 cases (22.1%) of varicocele, 8 cases of cryptorchidism including 3 bilateral, 4 cases of testicular atrophy and 13 cases of testicular hypotrophy. The semen analysis was performed on 94 patients. In one case there was an anejaculation. The Urine culture in post coital period performed twice did not find any sperm.

The spermatic balance of the whole study population was disrupted. The spermatic profile of our sample was reported in Figure 2.

Azoospermia was found in 47.6% (N = 10) of subjects with varicocele. The semen culture isolated a germ in 18 cases (19.1%). It was the staph in 12.7% of cases (N = 12), streptococcus in 2.1% of cases (N = 2) and pseudomonas in 1% of cases (N = 1). Candida albicans was isolated in 3 cases. In these three cases, the collection of sperm occurred in the laboratory by interrupted coitus.

Determination of serum FSH was performed by 57.9% (N = 55) patients. The rate was normal in 52.7% of cases (N = 29) and increased in 47.3% of cases. The elevation of FSH was found in 40.5% (N = 17) of azoospermia. The blood level of testosterone was achieved by 45 patients. The testosterone was low in 3 cases and normal in 42 cases.

Compared to other African series, the annual incidence of male infertility in our study was low. Its concerned 3% of all consultations in the service. It accounted for 8.2% of all consultations in the series of Bah et al. in Guinea Conakry [7] . This low frequency of the disease in our series does not seem to reflect the actual level of pathology in hospitals let alone society. The route of the infertile couple in southern societies seems more complex [1] . The use of traditional healer and religious circles for prayers first intension is the rule. This attitude is motivated by the level of knowledge on the issue and the socio-cultural aspects of infertility [1] [2] [8] .

In hospitals, two medical specialties share the management of male infertility. These are the obstetrics gynecology and urology and rology. Obstetric gynecologist is the specialty at the forefront. Most of our patients (77.9%) were referred by the gynecologist. Patients referred to the urology consultation for infertility would be those who have deep sperm alterations requiring uro-andrology exploration. Urology seems to be the last resort in the treatment of male infertility in our practice.

Age is known as a determining factor in the fertility of the couple. It is more damaging in the female. The decline in male fertility with age is a well-accepted concept [9] . The reasons given are many involving impairment of sperm parameters to genomic alterations of the sperm with age [10] . Those reasons are amplified by an alteration of sperm parameters recorded in the last two decades [6] . This is a disease in young patients in the African series, 34 in the series of Ahmed et al. in Nigeria [11] , 39 in the series of Bah et al. in Guinea Conakry [7] and that of Niang et al. in Senegal [12] and 36.9 years in our series. The primary type of infertility was predominant in most series [7] [11] [12] confirming our observations. In all cases the etiological research is an absolute necessity. Urogenital infections, main providers of obstruction of sperm ducts were found in 24.2% of patients in the study population. In addition to the obstruction they cause infections lead to a destruction of germ cells [13] . It is irreversible, these cells do not have the capacity to renew itself. Sperm quality can provide guidance on the infectious origin of the alteration; oligospermia, viscosity increase, decreased pH, low concentration of secreted by glands [13] components. Urogenital infections are the main causes of infertility both in men than in women of African environment [4] [11] [14] . It can be active infection or sequelae. Once formed, the results of management of infertility are random. Several pathogens infecting the male urogenital tract have been implicated. Gonorrhea was the most found in the study of Bah et al. [7] . Staphylococcus was the most found in the semen culture in our series as well as in the series of Owolabie et al. [15] in Nigeria. The relationship between schistosomiasis infection and male infertility is a particularity of the African environment. Patil et al. [16] were found in a study autopsy prostate achieved in nearly 58% and a violation of the seminal vesicles in 50% of cases. Schistosoma haematobium was the only involved agent. Frequently, the infestation is old since childhood or adolescence. It could have been symptomatic or not, treated or untreated. The actual impact of urogenital schistosomiasis in the occurrence of male infertility remains unclear. Its contributed by them aftermath which were irreversible. We found a history of urogenital schistosomiasis in 6 cases (6.3%).

Varicocele was the most observed physical signs (22.1%). Its involvement in the genesis of male infertility remains controversial. Its management is more so especially in developed countries where the use of medically assisted procreation seems more advantageous in terms of cost and performance [17] .

The spermatic balance was disturbed in all patients. Azoospermia was the most anomaly found (44.7%). The high prevalence of infectious and surgical history, anomalies reported by physical and ultrasound examination are crucial elements of the spermatic balance disturbances. The rates of different sperm abnormalities are variable depending on the series. Owolabi et al. [15] in Nigeria, Lee et al. [18] in Korea and Bah et al. [7] in Guinea Conakry reported respectively 6.2%, 10.5% and 39.3% of azoospermia. The management of a zoospermia remains a challenge for the urologyst. It is guided by its etiology. Azoospermia were grouped into two categories: obstructive azoospermia and non obstructive azoospermia. Obstructive azoospermia are more common in Afri- can environment because of the prevalence of infectious diseases [11] [12] [19] . The high rate of azoospermia associated with anormal FSH levels (59.5% of azoospermia) in our series argues for an obstructive etiology most likely acquired in our context. In the series of Lee et al. [18] obstructive azoospermia and non-obstructive azoospermia represented respectively 25% and 71% of all azoospermia. Azoospermia in our study was associat- ed with elevated FSH levels in 40.5% of cases moving towards gonadal causes. Testicular biopsy and histology have helped refine the diagnosis. This exploration is exceptional in our practice. This information can’t be reduced only to the diagnosis. Significant advances in the field of reproductive biology have been made in recent years especially in the field of genetics [5] reducing the scope of idiopathic infertility. In the series Lee et al. [18] , chromosomal abnormalities were the second leading cause of non obstructive azoospermia. In our practice, exploration of male infertility is limited to the clinical examination, the spermatic balance sheet, endocrinology and ultrasound. The cost of examinations especially hormonology same routine is a hindrance to exploration rights. Only 57.9% of our sample was able to achieve a dosage of FSH.

The exploration of the male infertility with gradual approach will often determine the obvious causes. Urogenital infections were the most frequent diagnoses found in our environment. A logical management of male infertility should interest man and his partner by the same multidisciplinary team including at least uro-andrologist, gynecologist and reproductive biologist. This could raise the level of health care provision and identify areas of research to better management of male infertility.
