A 65-year-old Berlin woman, who already has 13 children, is pregnant again with quadruplets, reports Germany's RTL broadcaster.
Annegret Raunigk made headlines 10 years ago when she gave birth to her 13th child at the age of 55.
The Russian and English teacher's pregnancy, whose oldest children is 44-years-old, follows several attempts abroad at artificial insemination over the last 18 months.
Her decision to have another child came after her youngest daughter, who is nine, asked for a little brother or sister, the RTL channel reported on its website.
It said it would broadcast an interview with the expectant mother, who has seven grandchildren, on Monday evening and plans to track her through the pregnancy and afterwards.
It said the pregnancy had so far been without any major complications and that if everything went well, the babies were due in the summer and that Ms Raunigk would be the world's oldest mother of quadruplets.
Mass circulation newspaper Bild am Sonntag reported the four-baby pregnancy on its front-page, quoting the prospective mother-of-17, recalling the moment doctors broke the news.
"Certainly that was a shock for me. After the doctor discovered there were four, I had to give it some thought to begin with."
"On the scan it was just clear to see," Bild quoted her as saying, adding however she had not considered it an option to reduce the number of embryos.
"At first, I only wanted one child," Bild quoted her as saying at the time. "Not all were planned. But then things happen. I'm not a planner but rather spontaneous. And children keep me young."
At a time when other women her age are preparing to slow down and take things easier, Ms Raunigk indicated she had no reservations about the challenges ahead.
"I'm not actually afraid. I simply assume I'll remain healthy and fit. In matters of organisation I have enough experience, that's not new for me," she said.
Asked about moral doubts, RTL quoted her as asking: "How does one have to be at 65? One must apparently always fit some cliches which I find rather tiring."
