Epidemiological and Clinical Pattern of Patients with Female Infertility Prior Hysteroscopy at Yaoundé ()
1. Introduction
Worldwide, infertility concerns approximately 15% of couples of reproductive age [1]-[3]. The causes of infertility are divided into female, male, mixed, and idiopathic causes.
In Cameroon, a previous study revealed that the etiology of infertility in our population was predominantly female, accounting for 177/406 cases (43.6%), followed by male factors in 114/406 cases (28.1%). Overall, at least one female factor was found in 263/406 cases (64.8%) [4]. Uterine pathologies generally considered to be involved in infertility include fibroids, polyps, uterine synechiae, and congenital anomalies.
Hysteroscopy has proved to be useful in the diagnosis and management of intrauterine pathologies [5] [6].
We undertook this research to determine the clinical profile of patients with uterine-related female infertility at the Gynecological Endoscopic Surgery and Human Reproduction Teaching Hospital of Yaoundé (GESHRTH) awaiting hysteroscopy.
2. Materials and Methods
We conducted a prospective cross-sectional study covering the period January 2016 to June 2023 (eight years) at the Gynecological Endoscopic Surgery and Human Reproduction Teaching Hospital of Yaoundé (GESHRTH). The GESHRTH is a specialized center addressing infertility issues with IVF in Yaoundé.
The target population was all patients with exclusive female infertility and proof of intracavitary pathology awaiting hysteroscopy. Transvaginal ultrasound, saline hysterosonography, and hysterosalpingography were used to identify intracavitary pathology. We excluded files of patients with mixed infertility and patients with co-existing other female factors. The semen analysis of patients’ partners was used to exclude male infertility. While hysterosalpingography was used to rule out tubal infertility. The minimum sample size was estimated based on the Cochrane formula. The sampling method was consecutive.
After obtaining ethical clearance and research authorizations, we identified patients’ records from operating room registers, retrieved files, and filled out the established and pretested data collection form. Besides, to deal with missing data on the files, we collected the phone numbers of those patients, called them to obtain verbal informed consent, and interviewed them. Data analysis was performed using Cs Pro version 8.0 and R Studio version 2024.12.1-563.
3. Results
We retained 126 cases (Figure 1). The mean age of our patients was 37.9 years ± 5.5 years, with extremes of 25 and 45 years. The median age was 39 years. Figure 2 shows that the [40 - 45[ years age group was the most represented with 45 patients (35.7%).

Concerning socio-demographic characteristics of our study population, as shown in Table 1, 81 patients (64.3%) were married. The majority of them have a higher education level (66.7%), followed by secondary level (27.8%). Private sector and civil servants were the most represented occupations recorded with 42.1% and 38.9% respectively.
Regarding the past history of our patients (Table 2), HIV infection was noticed in 12 patients (9.5%), whereas high blood pressure and diabetes were reported in 3.2% and 2.4% cases, respectively. A past history of myomectomy and cesarean section was noticed in 35 (27.8%) and 22 (17.5%) cases. In addition, a past hysteroscopic procedure was observed with management of synechia in 4 (3.2%), polypectomy in 2 (1.6%), and resection of the uterine septum in 1 (0.8%).

Concerning the gynecological and obstetrical history, the mean age of menarche was 13.8 years ± 1.8 years, with extremes of 10 and 19 years. The mean length of the menstrual cycle was 28.3 days ± 3.7 days, with extremes of 25 and 36 days.
The mean parity was 0.6 ± 0.8 with extremes of 0 and 3. A past history of abortion was reported in 71 (74.7%), with a curettage done in 32 cases (25.4%).
As part of clinical signs (Table 3), dysmenorrhea, menorrhagia, and dyspareunia were the most frequent signs with 52 (41.3%), 35 (27.8%), and 23 (18.5%), respectively. Besides, secondary infertility was noticed in most cases, 92 (73%). The mean duration of infertility was 7.8 years ± 4.6 years, extremes 1 and 22 years. The [5 - 10[ years group was the most represented (42.9%).

On routine scanning, intrauterine anomalies observed (Table 4) were submucosal fibroids in 82 (65%). The mean number of fibroids per patient was 4.1 ± 3.1 (Min 1 - Max 13). The mean size of fibroids was 3.4 cm ± 1.8 cm (Min 0.9 – Max 10.8). In addition, polyps and synechia were found in 72 (59.5%) and 17 (13.9%).

4. Discussion
In our study, the mean age of our patients was 37.9 years ± 5.5 years. This figure was already found by Nyada et al. and Noa Ndoua et al. with 38.7 years ± 7.6 years and 39.3 years ± 7.8 years, respectively [7] [8]. These results are consistent with the profile of patients who consult at GESHRTH, a facility dedicated to addressing infertility issues.
The majority of our patients had a higher level of education; our results are similar to those of Voundi et al. in 2025. The latter found that the risk of infertility increases with the level of education, women with higher education having 10.44 times the risk of infertility than those with a secondary education [4]. This could be explained by the societal and professional pressures that women face, thus relegating the desire for motherhood to a secondary concern.
In our study, patients working in the private sector were mostly frequent. Our results are comparable to those of Voundi et al., who found that the risk of seeking help for female infertility was 4.9 times higher for women working in the private sector. The private sector appears to involve more physical or psychological constraints and consequently impacts the desire for motherhood.
Dysmenorrhea (41.3%), menorrhagia (27.8%), dyspareunia (18.3%), and amenorrhea (11.1%) were the main clinical signs found in our patients apart from the inability to conceive. Our results are similar to those of Noa Ndoua et al., who found, with the exception of dyspareunia, that dysmenorrhea, menorrhagia, and amenorrhea were the main clinical symptoms in infertile patients [8].
A past history of abortion was recorded in 74.7% of our patients, with curettage as management in 33.8%. Noa Ndoua et al. and Nyada et al. found the same figures [7] [8]. The high proportion of curettage could explain the occurrence of uterine synechiae.
Fibroids are the most frequently occurring benign tumors of the uterus. Therefore, a history of myomectomy was recorded in 27.8% of our patients.
Secondary infertility was the most common in our study (73%). Our results are similar to those of Sule et al. in Nigeria, who found 77.5% [9]. Odunvbun also found similar results, with 76.8% [10].
The main abnormalities detected were fibroids (65%), polyps (59.5%), and synechiae (13.9%); our results are consistent with those of Ray-Offor et al. in Nigeria in 2021 [11].
5. Limitations
This was a single-center design study in a specialized center, which may include selection bias. Furthermore, it was a descriptive study with no comparison done. And we chose to rely on pre-hysteroscopic scanning workup rather than hysteroscopic findings.
6. Conclusion
Patients with intracavitary female infertility awaiting hysteroscopy at GESHRTH have a mean age of 37.9 years, and most have a higher education level. The majority have secondary infertility that has been present for 7.8 years, and the identified intracavitary lesions are fibroids (65%), polyps (59.5%), and synechiae (13.9%).
