As it turns out, the color of an egg's shell is determined by the breed of chicken that lays it. Brown eggs often cost more than white ones because they're usually laid by a larger breed of hen that requires more food, which makes the eggs more expensive for farmers to produce.

Mangamma gave birth to twins at the age of 74 through in-vitro fertilisation via caesarean section in Hyderabad, India.
Ovarian reserve testing is a test healthcare providers use to evaluate your fertility potential. This means the results are interpreted as a comparison to people the same age as you. Ovarian reserve testing uses a blood test and a vaginal ultrasound to estimate your egg count.
There is good evidence that even after menopause (up to the age of 60 years old), the ovaries produce small amounts of female hormones, which help to maintain both bone and cardiovascular health. This hormone production stops at 60 years old. There is no benefit to keep your ovaries after the age of 60yo.
