According to recent news reports, a woman in England became pregnant when she was already pregnant and eventually gave birth to rare twins three weeks apart.
Usually, when a woman becomes pregnant, her body initiates some biological processes designed to prevent concurrent pregnancy, including releasing hormones to stop ovulation. However, in rare cases, a pregnant woman may continue to ovulate or release an egg, which can then be fertilized by sperm and implanted in the uterus. This rare phenomenon is the implantation of two fertilized eggs into the uterus at different times. This phenomenon is called “super fetus.”

At 12 weeks of pregnancy, the doctor found a second baby during an ultrasound examination, whose size was three weeks different from the first baby. Because overweight is very rare, Roberts’ doctors were unable to explain the difference in size between the two babies at first.

“My initial reaction was that I missed the second twin,” Dr. David Walker, an obstetrician and gynecologist at the Royal Women’s Hospital in Bath, told Good Morning America. “then [I] It was not my fault, but an extraordinary pregnancy, and I felt relieved about it. “

The doctor diagnosed Roberts as having hyperspermia and told her that the baby might not survive. When Roberts was 33 weeks pregnant, in September of last year, doctors induced a childbirth because the young twin Rosalie stopped growing normally due to an umbilical cord problem.
The older twins Noah (Noah) stayed in the neonatal intensive care unit (NICU) for three weeks and Rosalie (Rosalie) stayed for 95 days. Now, both babies can go home and stay healthy.

Roberts told the Good Morning America: “When we put them together, as they knew immediately-they reached out and touched each other’s faces, that was the most beautiful thing.” “Anyway, twins have it.” Stunning connection, but the story between these two, when they are big enough to be discovered, they will feel even more different.”
It is not yet clear how many types of overmarriage have occurred. According to the “Life Science” report, because the fetuses are so close in age and so large in size that they are considered ordinary twins, many cases may go undetected. According to Healthline, the most common cases of superconception involve patients using assisted reproductive technologies (such as in vitro fertilization).

Nevertheless, this phenomenon is considered extremely rare, because three separate, impossible events must occur: ovulation (usually prevented by pregnancy hormones), and fertilization (usually stopped by mucus blockage in the early stages of pregnancy). According to Healthline, “This form prevents sperm from passing through the cervix) and implantation (which requires enough space to accommodate another embryo in the uterus, and hormones that are normally not released once someone becomes pregnant). But in other Among animals (such as fish, hares, and badges), super fat is actually quite common.
