Female infertility in Niger: clinical characteristics, etiologies and challenges in access to assisted reproductive care in a tertiary referral hospital

In many parts of the world, the ability to have children is often taken for granted, but for millions of couples, the path to parenthood is blocked by medical conditions that prevent conception. This condition, known as infertility, is defined as the inability to become pregnant after a year of regular, unprotected attempts. While the biological reasons for this struggle vary widely—from hormonal imbalances that stop the release of eggs to physical blockages in the tubes that carry them—the social weight of childlessness is particularly heavy in certain regions. In many African societies, where family identity and marital stability are deeply tied to having children, the inability to conceive can lead to profound social stigma and personal distress. Despite the existence of advanced medical treatments that can help couples overcome these barriers, access to such care is often limited in low-resource settings, leaving many without a clear path forward.

Researchers in Niger recently sought to understand the specific landscape of this challenge within their own country. They conducted a detailed review of medical records at the National Referral Hospital in Niamey, the nation's primary center for advanced care, looking at the experiences of women who sought help for infertility between 2022 and 2024. By examining the files of nearly 400 women, the team aimed to map out who was struggling, why they were struggling, and what medical options were actually available to them. Their work provides a rare, clear window into the reality of fertility care in a region where data has been scarce, revealing a pattern of causes and barriers that differs significantly from what is seen in wealthier nations.

The study began by looking at the sheer scale of the issue within the hospital. Out of more than 2,100 women who visited the clinic during the three-year period, nearly 400 were being treated for infertility. This means that roughly one in every five women seeking care at this major facility was there because she could not conceive. The researchers found that the women facing this challenge were typically in their thirties, with the largest group falling between the ages of 30 and 39. Interestingly, more than half of these women were not experiencing their first struggle with conception; they had previously had children but were now unable to conceive again. This condition, known as secondary infertility, was more common than primary infertility, where a woman has never been able to conceive at all.

When the medical team investigated the root causes of these struggles, a clear picture emerged. The most frequent culprit was damage to the fallopian tubes, the delicate pathways that transport eggs from the ovaries to the uterus. In over a third of the cases, these tubes were blocked or damaged, often due to past infections or inflammation. Hormonal disorders, which disrupt the body's natural cycle of egg release, were the second most common cause, followed by structural issues with the uterus itself. The investigation did not stop with the women; the researchers also examined the partners and found that in nearly one-third of the couples, the male partner had sperm that was either missing, malformed, or infected. This highlighted that infertility is often a shared challenge requiring the evaluation of both partners.

The journey to a solution, however, was fraught with obstacles. The most common treatment offered was medication designed to stimulate the ovaries to release eggs, a strategy used for more than half of the women. Some women underwent surgery to remove fibroids or repair tubes, but these procedures were available to only a small fraction of the patients. The most significant barrier appeared when the researchers looked at advanced treatments. Nearly half of the women in the study had medical conditions that would require in vitro fertilization, a process where eggs are fertilized by sperm in a laboratory and the resulting embryo is placed back into the uterus. Despite this clear need, the hospital did not have the equipment or technology to perform these procedures. Consequently, only a tiny number of couples were able to undergo less advanced artificial insemination, where sperm is placed directly into the uterus, while the vast majority of those needing the most sophisticated help were left without local options.

The financial reality of seeking care added another layer of difficulty. The cost of the diagnostic tests and medical treatments available in Niger was high relative to the average household income. While a course of medication and basic testing cost a few hundred dollars, and surgery cost slightly less, the inability to access the most effective treatments meant that many couples were spending money on interventions that had a low chance of success for their specific condition. The results of these efforts were modest: out of all the women treated, fewer than one in ten achieved a clinical pregnancy, and of those, some pregnancies ended in miscarriage. The researchers noted that the overall success rate was lower than what has been reported in some other African fertility centers, likely due to the combination of delayed diagnosis, the high prevalence of tubal damage, and the lack of advanced reproductive technologies.

The study also identified specific factors that made it more likely for a woman to be struggling with secondary infertility. Women who were older, who worked in salaried jobs, and who had previously given birth via cesarean section were more likely to be in the group facing secondary infertility. This suggests that the medical history of a woman, including past surgeries and infections, plays a critical role in her future fertility. The researchers concluded that the situation in Niger is defined by a heavy burden of preventable reproductive diseases, particularly those affecting the tubes, and a severe lack of access to the advanced care that could help these women. They emphasized that to improve the situation, national health policies must prioritize preventing infections that damage reproductive organs and work toward making fertility treatments more affordable and available. Without these changes, the cycle of infertility and the social hardships it brings will continue to affect countless families.
