Transplanted ovaries adjust to recipient biological age in mouse study
Older mouse ovaries became active again after being transplanted into younger animals, allowing them to produce healthy offspring, New Scientist reported.

Ovaries from older mice that were no longer able to reproduce became active again after being transplanted into younger animals, according to New Scientist. The young mice subsequently gave birth to healthy offspring. [1]
The findings suggest that the body of a younger host lowers the molecular age of the transplanted older organs, New Scientist reported. The study showed that the recipient animals were able to restore functional reproductive capacity to the older tissue. [1]
In vitro fertilisation is a process where an egg is combined with sperm in a laboratory before being transferred to the uterus to establish a pregnancy. In contrast, the mouse study involved direct tissue transplantation between animals of different ages. [1][2]
Transplanting younger ovaries into older mice also improved the overall health of the recipient animals, according to New Scientist. [1]
In short
- Older mouse ovaries became active again when transplanted into younger hosts.
- Young mice with transplanted older ovaries successfully gave birth to healthy offspring.
- Transplanting younger ovaries into older mice boosted the recipients' overall health.
