When Mariam Nabatanzi from Uganda gave birth to her first set of twins at just 13 years old, she had no idea her life would become one of the most extraordinary stories in modern medical history. Over the next two decades, she gave birth to 44 children through a remarkable series of multiple pregnancies, including six sets of twins, four sets of triplets and three sets of quadruplets. Her story earned global attention, with many media outlets dubbing her the world’s most fertile woman. Behind the astonishing numbers, however, lies a deeply human story of child marriage, a rare medical condition, poverty and a mother’s determination to raise one of the world’s largest documented families.
How the world’s most fertile woman became the mother of 44 children
Born in 1980 in Uganda, Mariam Nabatanzi was married off at the age of 12 in what has been widely reported as a child marriage. A year later, she became a mother after giving birth to her first set of twins. Instead of spending her teenage years in school, she found herself caring for children while still growing up herself.In interviews with Reuters, Mariam revealed that she had once hoped to have only six children. She wanted to rebuild the family she had lost after her mother abandoned them, and according to her account, five of her older siblings later died after allegedly being poisoned by their stepmother. Reflecting on her early life, she said, “I started taking on adult responsibilities at an early stage. I have not had joy, I think, since I was born.“Over approximately 25 years, Mariam gave birth 38 times, resulting in 44 children because of repeated multiple births. Her pregnancies included six sets of twins, four sets of triplets, three sets of quadruplets and two single births. Tragically, six of her children later died, leaving her to raise 38 surviving children.The extraordinary frequency of multiple births made her case one of the best documented in modern medicine. Unlike many historical claims about exceptionally large families, Mariam’s pregnancies have been extensively reported and medically documented, making her story unique among contemporary cases.
The rare medical condition behind the multiple births
Doctors later diagnosed Mariam with hyperovulation, a condition in which the ovaries release multiple eggs during a single menstrual cycle instead of the usual one. When several eggs are fertilised, the chances of twins, triplets or quadruplets increase dramatically.According to Dr Charles Kiggundu, a gynaecologist at Mulago National Specialised Hospital in Kampala, Mariam’s unusually large ovaries caused her to release multiple eggs repeatedly, making successive multiple pregnancies far more likely than in the average woman. While hyperovulation itself is not unheard of, specialists say a case involving repeated high-order multiple births over so many years is exceptionally rare.Medical experts also note that genetics plays an important role in hyperovulation, which is why fraternal twins often run in families. However, having repeated pregnancies resulting in triplets and quadruplets remains an extremely uncommon occurrence.
Why doctors did not stop the pregnancies earlier
After several pregnancies, Mariam sought medical help because she did not want any more children. However, according to interviews she later gave, doctors initially advised against certain birth control methods because of concerns about complications linked to her enlarged ovaries.As a result, she continued becoming pregnant until her final delivery. After giving birth to her last child, doctors performed a tubal ligation, a surgical procedure that permanently prevents pregnancy, bringing one of the most remarkable childbearing histories ever documented to an end.
Raising dozens of children on her own
Life became even more challenging when Mariam’s husband reportedly abandoned the family in 2015. Left to care for dozens of children alone, she took on whatever work she could find, including farming, tailoring, hairdressing, selling herbal medicines and decorating events.In one Reuters interview, Mariam described the constant struggle to provide for such a large household, saying, “All my time has been spent looking after my children and working to earn some money. I have grown up in tears, my man has passed me through a lot of suffering.”Her eldest son, Ivan Kibuka, also described the family’s daily reality, saying, “Mum is overwhelmed, the work is crushing her. We help where we can, like in cooking and washing, but she still carries the whole burden for the family.”Reports indicate the family has at times needed around 25 kilograms of maize flour every day simply to prepare enough food for everyone, while meat and fish were considered occasional luxuries because of their cost.
Life inside one of the world’s largest families
At various points, Mariam’s household has included more than 60 people, including children, grandchildren and daughters-in-law. The family lives in several modest brick houses with corrugated iron roofs, where older siblings help cook, clean and care for the younger children.Despite the enormous responsibilities, Mariam has repeatedly stressed the importance of education. Whenever possible, she has prioritised sending her children to school, believing education offers them opportunities she never had.Mariam Nabatanzi’s life is about far more than giving birth to 44 children. Her story highlights the lasting effects of child marriage, the importance of maternal healthcare and the challenges of raising a large family in poverty. While the world may remember her for an extraordinary medical rarity, her greatest achievement has been raising dozens of children despite overwhelming financial and personal hardships.
