A thirty-four-year-old lawyer in Ikoyi has had crippling pelvic pain on the second and third days of every cycle since she was fifteen. She describes it, when she is finally asked properly, as a wire pulled tight from the small of her back through her pelvis and twisted slowly for about thirty-six hours. The first gynaecologist she saw, when she was nineteen, told her some women just have heavier periods and prescribed mefenamic acid. The second, at twenty-six, told her that the pain was probably stress and that she should consider seeing someone about her anxiety. The third, at thirty-one, told her — and she has remembered the exact phrasing for three years — that she would feel better when she got married and had children.
She has not had children. She has been trying, with her husband, for four years. At the fertility workup last month a transvaginal ultrasound performed by a sonographer who knew what to look for surfaced bilateral endometriomas, deep infiltrating disease across the pouch of Douglas, and what the radiologist’s report described, with admirable understatement, as “extensive endometriotic burden, consistent with long-standing untreated disease.” She is nineteen years late to her diagnosis. The conversation she got to have with her reproductive endocrinologist last week was about IVF success rates given her ovarian reserve, not about treatment options she might have had at twenty.
This is not hypothetical. The international literature on endometriosis has converged for two decades around a delay-to-diagnosis figure that no specialty in clinical medicine should be comfortable with. Nnoaham and colleagues, in the multi-country World Endometriosis Research Foundation study published in Fertility and Sterility in 2011, reported a mean diagnostic delay of 6.7 years from symptom onset, with the upper end of the country-level distribution exceeding ten. Hudelist’s Austrian-German cohort the same year landed at 10.4 years. The Endometriosis UK figures, repeatedly cited, have hovered around seven to eight. The 2022 European Society of Human Reproduction and Embryology guideline opens by naming the delay explicitly, and devotes a substantial part of its updated recommendations to closing it by moving the diagnostic threshold off the laparoscopic gold standard and onto clinical and imaging grounds — because the gold-standard surgical confirmation, while diagnostically clean, has itself become part of the bottleneck.
The Nigerian delay is worse. There is no clean published figure for the local mean — the studies that exist are small, hospital-based, and likely undersample the women who never reach a tertiary gynaecology clinic — but the clinical experience of any Nigerian gynaecologist who treats the condition seriously is that the patient in front of them has typically been in pain for a decade or more, has been seen by multiple doctors, and has been told some version of one of three things. That the pain is normal. That the pain is psychological. That marriage and childbirth will fix it. None of these is medicine. All of them delay diagnosis, and the delay is measured in fertility, in working life, in marriages, and in the patient’s slow, quiet loss of faith that the medical system intends to help her.
The second vignette
A twenty-eight-year-old marketing director in Wuse II — different demographic, more privileged access, more confident about her own body — started having cyclical pain at twenty-one and went to her family’s gynaecologist within the first year. She was told it was normal. She tried two more gynaecologists over the next eighteen months and was told it was normal twice more. At twenty-four, having read enough online to be specifically afraid of the word endometriosis, she walked into the consulting room of a Lagos-based gynaecologist with a printed list of her symptoms scored against the international diagnostic criteria she had found in an ESHRE patient leaflet, and asked, in plain language, for a diagnostic laparoscopy.
She got it. The disease was moderate. She has been on appropriate hormonal management since, has had her fertility counselling proactively rather than reactively, and is the lucky one in this piece. The mechanism that delivered her the diagnosis four years late rather than nineteen years late was not better medicine in the room. It was her, alone, advocating for herself harder than any patient with a comparable cardiovascular symptom would ever be required to do. She had to read the European guidelines herself to get the test her physician should have ordered. That is the structural fact this piece is trying to name.
What endometriosis actually is
Endometriosis is the presence of endometrial-like tissue — glandular and stromal, hormonally responsive, behaving cyclically — outside the uterine cavity. The lesions most commonly occupy the pelvic peritoneum, the ovaries (where they form the chocolate cysts properly called endometriomas), the uterosacral ligaments, and the pouch of Douglas; deep infiltrating disease extends into the bowel wall, the bladder, the ureters, and occasionally the diaphragm. Each cycle, under the same hormonal signals that drive the eutopic endometrium, the ectopic lesions bleed, inflame the surrounding tissue, and over years lay down adhesions and fibrosis that distort pelvic anatomy and produce the specific pattern of pain the condition is known for.
That pain is cyclical at first and then becomes constant. It is concentrated in the pelvis but radiates to the back, the thighs, the rectum. It is exacerbated by intercourse — dyspareunia — and by defecation around menses — dyschezia — and by micturition where bladder disease is present. It is associated, in a substantial subset of patients, with primary infertility through the combined mechanisms of anatomical distortion, inflammatory effects on oocyte and embryo quality, and impaired tubal function. The 2022 ESHRE guideline now formally recognises that the condition causes a chronic pain syndrome with central sensitisation in a meaningful proportion of long-untreated patients, which is why pain often persists after surgical excision in women diagnosed late — the peripheral disease has, by then, retrained the central nervous system.
Prevalence in reproductive-age women globally sits at approximately 10 percent. The Nigerian figure, where it has been studied, is consistent with that range. It is not a rare disease. It is, by any reasonable accounting, one of the most common chronic conditions in Nigerian women of reproductive age, and one of the most systematically under-diagnosed.
The diagnostic standard has, until recently, been laparoscopic visualisation with histological confirmation. The 2022 ESHRE guideline has moved deliberately away from that as a prerequisite for diagnosis and treatment, recognising that requiring a surgical procedure to start care is itself a contributor to the delay. A clinical diagnosis can now be made on history, examination, and quality imaging, with surgery reserved for cases where it adds clear value — either through definitive excision or because medical management has failed. That shift exists specifically to shorten the diagnostic delay. In Nigeria, where laparoscopic gynaecology is concentrated in a handful of centres and where many women would not be offered the surgery in any case, the guideline change should — in theory — help. In practice it only helps if the clinical and imaging steps are done at all.
Why the Nigerian delay is worse
Three structural reasons compound, and they are why a condition with reasonably well-mapped clinical criteria is missed for sixteen years in a Lagos lawyer with comprehensive private insurance and the resources to consult any gynaecologist she chooses.
The first is the cultural script. The single most common sentence Nigerian women hear from clinicians, family, and one another about menstrual pain is that pain is normal. It is not. Pain that disrupts work, that requires bed rest, that does not respond to over-the-counter analgesia, that is associated with vomiting or syncope, that interferes with relationships or fertility, that scales in severity with the menstrual cycle in a reproducible pattern — none of that is normal. All of it is clinical signal. The script that flattens severe pain into the same category as mild cramping is doing real diagnostic damage, and it is being spoken in the consulting room as often as in the family living room. A nineteen-year-old who is told by her gynaecologist that her pain is normal has been told it by an authority she had no reason to doubt, and she will carry that sentence forward for the next decade before she stops believing it.
The second is the fertility script. The advice to get married and have children, offered as a response to gynaecological pain, is not medicine. It is a life-event recommendation in place of a clinical workup. It is offered in clinics that should know better, and it does two specific kinds of harm. It delays the diagnosis by years — the patient leaves the consultation feeling that the medical question has been answered when it has not — and it forecloses the management decisions that would have most affected her future fertility. By the time she presents back at thirty-four with primary infertility, the disease that should have been managed at twenty has done what untreated disease does. The advice was wrong at the time it was given. It is no less wrong because it was given gently.
The third is the diagnostic infrastructure gap. Endometriosis-aware gynaecology — clinicians who think of the diagnosis early, sonographers trained to look for the specific markers of deep infiltrating disease on transvaginal ultrasound, MRI protocols configured for pelvic endometriosis mapping, multidisciplinary teams that combine gynaecology with pain medicine and fertility — is concentrated in a small number of Lagos and Abuja centres. Most Nigerian women presenting with cyclical pelvic pain see general gynaecologists for whom endometriosis is not high on the differential, and undergo imaging by sonographers who were not trained on the disease and would not recognise its early sonographic signatures. The patient is not failing the system. The system is failing to look.
The third vignette
A twenty-three-year-old graduate student in Abuja, registered with a concierge family physician for two years because her diaspora-based sister pays the membership, mentions during her annual physical that her periods have become noticeably more painful over the last eight months. The physician asks. He asks her to describe the pain, when in the cycle it falls, how it compares with what she had at sixteen, whether it disrupts her work or sleep, whether intercourse hurts, whether defecation hurts around her period, whether there is a family history. He does not interrupt and he does not minimise. He refers her — by name, with a written summary of the consultation — to a Lagos-based gynaecologist who runs an endometriosis service and who, in his experience, takes new presentations seriously.
The transvaginal ultrasound, done by a sonographer the gynaecologist trusts, shows mild ovarian involvement and early markers of pouch-of-Douglas disease. She is started on appropriate hormonal management. She is given a fertility-preservation conversation now, at twenty-three, while the conversation can still meaningfully shape her decisions. She is two years into her diagnostic journey, not nineteen.
The fertility outcomes will be different. The pain trajectory will be different. The career disruption will be different. The mental-health cost — and the mental-health cost of being disbelieved repeatedly about one’s own pain is real and well documented — will be different. Nothing exceptional was done. A history was taken seriously, an examination was done with the right question in mind, the imaging was ordered to the right standard, and the referral was made to a clinician who knew the condition. That is the entire intervention. It is unremarkable medicine. It is also, in the Nigerian system as it currently runs, vanishingly rare.
What proper diagnostic and management actually looks like
The history is the diagnostic test. A pain calendar across at least two cycles. Pain scores. Cycle correlation. Impact on daily function. Dyspareunia, dyschezia, dysuria. Family history, because there is a heritable component. Where appropriate, the Endometriosis Health Profile-30 or comparable validated questionnaire, used not as a research instrument but as a clinical one — because it forces the conversation to cover ground the patient and clinician will otherwise skip. Most of the diagnostic work is done here. Most Nigerian gynaecology consultations do not include it.
Examination follows — performed gently, with attention to uterosacral nodularity, fixed retroversion, adnexal tenderness, and deep tenderness in the pouch of Douglas. Findings are not always present and their absence does not exclude the diagnosis, but the examination must be done.
Imaging is the next layer. Transvaginal ultrasound, done by a sonographer specifically trained on the endometriosis sonographic markers — kissing ovaries, sliding-sign assessment for pouch-of-Douglas obliteration, deep infiltrating nodules in the rectovaginal septum or bladder. Most Nigerian sonographers have not had this training. Where deep disease is suspected or the clinical picture is severe, pelvic MRI with an endometriosis-specific protocol becomes appropriate.
Management is multidisciplinary by nature. Gynaecology leads. Pain medicine contributes where central sensitisation is established or suspected. Fertility specialists are involved early where the patient is of reproductive age and the disease is more than minimal. Mental-health support is part of the management of the disease, not an adjunct — the experience of being repeatedly disbelieved about severe physical pain has measurable psychological cost.
The hormonal options are discussed honestly, with the patient as a participant rather than a recipient. Combined oral contraceptives. Progestin-only options including dienogest. GnRH analogues with appropriate add-back therapy for longer use. The levonorgestrel intrauterine system in selected cases. The choice belongs to the patient with the clinician’s honest counsel. Surgery — laparoscopic excision by a surgeon experienced in endometriosis — is appropriate in defined situations: failure of medical management, ovarian endometriomas where conservative observation is not warranted, deep infiltrating disease affecting bowel or urinary tract, fertility-related decisions where the surgical intervention has documented benefit. It is not the first answer, not the only answer, and not always the right answer.
What is lost when the conversation does not happen
The cost of the delay is measured in concrete things. Fertility, where untreated disease over a decade reshapes the pelvis and reduces ovarian reserve. Working life, where women lose days each cycle to pain they have been told is not real. Marriages, where dyspareunia goes undiscussed for years and the relational cost compounds in silence. Mental health, where the cumulative experience of being told by clinicians that the pain is in her head produces, in some patients, a depression that is iatrogenic in its origins. Faith in medicine, where the woman who was told three times that nothing was wrong eventually stops bringing other symptoms to clinicians at all.
The shape of what is happening here is the same shape we named in the men’s health piece on erectile dysfunction. An early-warning signal received by the patient, brought to a clinician, dismissed at the consulting-room threshold, accelerated by a cultural script that tells the patient the symptom is not the kind of thing medicine is for. The men’s version of that pattern unfolds over three years and ends at a catheter lab. The women’s version unfolds over a decade and ends in a fertility clinic. The mechanism is the same. The next piece in this series, on fibroids and the question of when surgery is the right answer, takes up the next thread of the same fabric.
What Kinedic does about it
The annual physical for any female member of our practice includes a real menstrual history, taken at length, by the named physician who will see her the following year. Pain scores. Cycle correlation. Functional impact. The questions are asked plainly and the answers are recorded. Cyclical pelvic pain that meets clinical criteria for further workup is referred — not deferred, not parked behind “come back if it gets worse” — to a named, credentialed, endometriosis-aware gynaecologist whom we have vetted and whom we trust. The referral is warm. The follow-up is owned by our practice, not handed off and forgotten.
The patient does not have to know what to ask for. She does not have to print the ESHRE guideline and walk into the consulting room ready to argue for her own diagnostic test. She does not have to have a sister in London paying for her care to be taken seriously. The relationship across the diagnostic and management arc — over the years it takes to actually manage this condition properly — is held by one physician who knows her file, who knows her, and whose job it is to make sure the years are not lost.
Closing
Endometriosis is one of the most common, most chronic, and most consequential conditions in Nigerian women’s health, and it is being missed for a decade or more at a time by a system that knows how to find it and chooses, repeatedly, not to look. The cost of that failure is being paid by women who were told their pain was normal, by women whose fertility was discussed only after it was already compromised, and by women who learned, in their twenties, that the medical system would not believe them about their own bodies.
The diagnosis is available. The management exists. The years do not have to be lost. If you have been in pain that you have been told is normal, and you suspect it is not, the next conversation does not have to be with the same clinician who has told you it is normal for the last decade. The first conversation is private and costs nothing.
