Hypogonadism refers to a syndrome that results from failure of gonadal function. It is a relatively rare disease that is underdiagnosed, with an unknown combined prevalence in both males and females worldwide [1]. Moreover, data is scarce in Africa. The most common presentation is delayed or absent puberty. Hypogonadism does not directly influence mortality but rather morbidity with an increased cardiovascular risk, infertility, osteoporosis and above all the psychological impact on the life of patients [2]. Psychological problems may go unnoticed if the physician does not address the subject first. In several African cultures, lack of adequate sex development is seen as a taboo. This may have a considerable sociocultural impact and cause stigmatisation among the patients. The principles of management of hypogonadism consist of sex steroid replacement and psychological support. Positive outcomes are obtained in most cases despite setbacks such as the risk of physical aggressiveness, increase sexual drive and suicidal tendencies [3-5]. Consequently, judicious steroid replacement and culturally-sensitive psychological support before and during steroid therapy remains the key tool in the management of this condition, especially in the context of limited access to health services and diagnostic methods of hypogonadism [6]. The present study aimed at filling the knowledge gap of hypogonadism in Cameroon.

 

 

We conducted a cross-sectional study, over a period of 12 months, from January to December 2016. Our study was conducted in the Yaoundé Central and General hospitals; and at the Douala General hospital where patients with hypogonadism seen during outpatient visits were included. We invited people with hypogonadism-related symptoms through an announcement to consult an endocrinologist in one of the 3 study sites. For patients who already had follow-up in each unit, we recorded data from their files. All consenting patients received at outpatient endocrinology consultation with a diagnosis of hypogonadism and aged 16-50 years for males and or 16-45 years for females [7, 8] were included. Females who had undergone total hysterectomy and those with Mayer-Rokitansky-Küster-Hauser syndrome were excluded. We did a consecutive sampling.

 

Data collection

 

Clinical data: for all patients we recorded medical history including cryptorchidism, mumps orchitis, impuberism, amenorrhea and their physiological age at the first consultation for hypogonadism-related symptoms. We also looked for symptoms such as anosmia and visual field defects. Family history of infertility or impuberism was also noted. Patients underwent a clinical exam where anthropometric parameters, eunuchoid presentation and specific signs of malformation such as web neck, narrow shoulders and cleft palates were assessed. Concerning external genital evaluation in men, we verified the presence of testes in the scrotum, measured testicular size with an orchidometer and the resting penile length using a tape then both were staged using the Tanner staging system. We evaluated and staged the female breast using the Tanner staging system. In both genders, pubic and axillary hair was evaluated for type and distribution and staged using the same staging system. Complete physical examination was conducted topographically.

 

Psychosocial aspect: we invited patients to fill a form that evaluated the direct effect of hypogonadism on their psychological state and the resultant psychosomatic disorder that could be associated with hypogonadism. We used the Middlesex Hospital Questionnaire (MHQ) that has been approved and considered valid, reliable [9, 10] and one of the most promising to be recommended in evaluating the psychological state of patients in non-psychiatric settings, appropriate for clinical and research practice [10]. This questionnaire has 48 questions and evaluates 6 psychological aspects: free floating anxiety, phobic anxiety, obsessive compulsive disorders, somatization, depression and hysterical traits. Each aspect is evaluated by 8 questions rated on a scale of 0 to 2.

 

Data analysis: data were collected and analyzed using SPSS software version 23. Student T-test was used to compare means and Spearman's correlation to establish relationship between qualitative variables. The results were expressed in terms of percentages for qualitative variables, medians and means for quantitative variables. The threshold of significance was set at a value p < 0.05.

 

Ethical consideration: institutional ethical clearance was obtained from the Ethical committee of the Faculty of Medicine and Biomedical Sciences of the University of Yaoundé I to carry out this study. Each participant gave his informed written consent. They were free to withdraw from the study at any time they wished. All information obtained or used in the study was kept confidential.

 

 

We recruited 59 patients including 30 females aged 29.0 ± 9.1and 29 males aged 30.8 ± 11.7 years. The majority (69.5%) of our patients were single. The majority of our population had BMI above normal. In females, 33.3% (10) had BMI between 25 and 30 Kg/m² and 33.3% (10) also had BMI between 30 and 35 kg/m². Whereas in the male population 34.5% (10) had BMI between 25 and 30 Kg/m² and 34.5% (10) also had BMI between 30 and 35 kg/m². The main presenting complaints in the females were primary amenorrhoea 53.3% (16) and secondary amenorrhoea 33.3% (10) (Table 1). In addition, 83.3% (15) had decreased libido, 63.3% (19) had primary amenorrhoea, 53.3% had sleep disorders, 53.3% had emotional lability, 50.0% (15) had irritability, 46.7% (14) had vaginal dryness, 40.0% (12) had secondary amenorrhoea and 72.2% (13) of those who desired conception were infertile. As regards clinical signs, 76.7% (23) had eunuchoid habitus, most were either in Tanner stage 3 or 4 for pubic hair development accounting for 36.7% (11) and 30.0% (9) respectively, whereas the majority of women were in either Tanner stage 5 or 3 for breast development accounting for 36.7% (11) and 30.0% (9) respectively. The only physical syndrome identified in females was Turner syndrome.

 

In the male population, micro-penis accounted for 48.3% (14) and small testes for 37.9% (11) of the presenting complaints. In addition, 75.9% (22) had sleep disorder, 72.4% (21) had both erectile dysfunction and low libido, 55.2% (16) had fatigue, 44.8% (13) irritability, 41.4% (12) had a high pitched voice and 14 had infertility. Concerning clinical signs, 79.3% (23) had eunuchoid habitus, 69.0% (20) lacked beard and most were in Tanner stage 3 or 4 for pubic hair development accounting for 34.5% (10) and 31.0% (9) respectively. On the other hand, 72.4% of the males had a penile length in Tanner stage 5, 62.1% (18) had gynecomastia. Kallman and Klinefelter syndromes were identified. In the overall population, the most common diagnosis was congenital hypogonadotropic hypogonadism seen in 44.1% (26) of the patients. Congenital hypergonadotropic hypogonadism was found in 22.0% (13), 18.6% (11) had acquired hypogonadotropic hypogonadism meanwhile 15.3% (9) had acquired hypergonadotropic hypogonadism. In female patients, the main etiology of central hypogonadism was NIHH with a prevalence of 20.0% (6). Peripheral or primary etiologies included primary ovarian failure (POF) accounting for 20.0% (6), Turner syndrome accounting for 16.7% (5), prolactinomas accounting for 13.3% (4) and pure gonadal dysgenesis in 10.0% (3) of the cases. On the other hand, male patients presented with NIHH in 34.5% (10) of the cases and 23.8% (4) of cases were part of the combined pituitary hormone deficiency syndrome (Table 2).

 

Correlation studies: there was a significant positive correlation between testicular volume measured using the orchidometer and that measured by testicular ultrasound with a correlation coefficient 0.860 and p-value < 0.001 on both sides. There was a positive correlation between the BMI and the level of androgens in both sexes.

 

Psychological profile: concerning the psychological profile in males, compulsive obsessive trait was common with a mean score of 8.6 ± 3.4 followed by phobic anxiety and depression with scores 7.8 ± 2.9. Meanwhile women presented a score of 9.2 ± 2.5 for compulsive obsessive trait, followed by phobic anxiety with a mean score 8.7 ± 2.7 and the minimum mean was 6.9 ± 2.1 for hysterical trait (Table 3).

 

 

This cross-sectional and observational study on hypogonadism in reference centers of a low resource setting shows the burden of late diagnosis, as the main presenting complaint was delayed or absent puberty and marked deteriorated psychological profiles in both sexes. Most patients consulted late given that the main complaint was delayed puberty and their mean age was 30.8 ± 11.5 years, for men and 27.7 ± 9.1 years for women. Delayed puberty is defined as the absence of secondary sexual characteristics or any signs of puberty beyond the normal age range for a given population. The common setpoint is 13 years in girls and 14 in boys [11]. Carel et al found an age of 22.7 ± 2.6 years in patients with Turner syndrome [12]. This age is lower than ours. However, another study conducted in our setting by Wonkam et al found a mean age 18.4 ± 2.8 years at diagnosis of Turner syndrome in a population of patients followed in Yaoundé [13]. Although both studies were conducted in Cameroon, the age difference could be due to the fact that Wonkam et al worked on a pediatric population. Patients reported late because the condition was not perceived as being pathologic. Hence these developmental abnormalities could go unnoticed or be neglected by parents or the patients themselves. Generally, it is at adulthood that the patients seeked the attention of a health professional because of the absence of secondary sexual characteristics, amenorrhoea in the context of a new relationship or the desire to procreate. Moreover, poor road infrastructure, low socio-economic backgrounds, illiteracy ignorance could contribute to the delay of diagnosis [14].

 

In contrast to literature that suggests hypergonadotropic hypogonadism as being more common than hypogonadotropic hypogonadism [1], NIHH was the main cause of hypogonadism in our population. This could be explained by the fact that our population was relatively small, and hospital based rather than community based. Some specificities were observed such as one patient presenting with a history of cleft palate, cleft lip and a normal sense of smell, suggesting a mutation of FGFR1 [15] or a mutation in FGF8 [16]. Furthermore, we observed in line with literature a stronger correlation between testicular volume measured by ultrasound and that measured by the orchidometer [17]. Thus, the orchidometer which is accessible, convenient and easy to use could be a promising tool for clinical practice and patient follow up in our resource-limited setting. Concerning the psychological profile of the patients, mean scores for phobic anxiety, obsessive compulsive disorders, depression and hysteria were greater than the standardized mean scores in psychoneurotic patients at psychiatrist consultation in contrast with some studies of Western countries. Georgopoulos et al found a satisfying psychological profile in congenital hypogonadotropic hypogonadism patients compared to a control group [18]. This result reflects the low acceptability of the condition in our cultural context that may worsen the psychological profile and further explain delayed consultation. Testosterone is known to have organizational, neurotropic and neuroprotective effects on the brain thus lack of androgen could contribute to the poor psychological profile we observed especially in primary hypogonadism and in Klinefelter Syndrome cases in particular [19].

 

 

Normosmic idiopathic hypogonadotropic hypogonadism (NIHH) is the most common presentation of hypogonadism in the study population. The clinical presentation of hypogonadism is heterogeneous and there is a significant psychosocial impact requiring further investigation and attention.
