Too much seed oil might hurt egg cells
Linoleic acid induces human ovarian granulosa cell inflammation and apoptosis through the ER-FOXO1-ROS-NFκB pathway

This study looked at what happens to egg-supporting cells when they're exposed to a fat called linoleic acid, found in seed oils. It found that too much of this fat can make the cells stressed and inflamed, and even cause them to die.
Surprising Findings
Linoleic acid activates estrogen receptors — not just inflammation pathways.
Most assume omega-6 fats cause harm only through inflammation, but this shows they may directly interfere with hormone systems, mimicking or disrupting estrogen signaling.
Practical Takeaways
Reduce intake of processed foods and seed oils (soybean, corn, sunflower) to lower linoleic acid exposure.

Linoleic acid might make certain human ovary cells more inflamed, based on lab tests with a specific dose.
In certain human ovarian tumor cells, a type of fat called linoleic acid turns on a protein pathway linked to inflammation and cell death, but this only happens if a chain of other molecules (ER, FOXO1, and ROS) are active first.
When a certain type of human ovary cell is exposed to a specific amount of linoleic acid, it starts to die off more — and this might explain why high levels of this fat could mess with egg development.
In certain human ovary tumor cells, a type of fat called linoleic acid seems to cause stress inside the cells, but blocking two specific proteins (ER and FOXO1) can undo that stress.
Eating too much omega-6 fat—especially from vegetable oils and meat from grain-fed animals—might increase body-wide inflammation, which could lead to long-term health problems like heart disease or diabetes.
