However, I can provide you with some information about the types of eggs and the menstrual cycle's follicular phase.

Types of Eggs:

1. Chicken Eggs - these are the most common type of eggs that we consume. They are laid by chickens and come in different sizes and colors.

2. Duck Eggs - these are larger than chicken eggs and have a creamier texture. They are commonly used in Asian cuisine.

3. Quail Eggs - these are smaller than chicken eggs and have a delicate flavor. They are often used in hors d'oeuvres and salads.

4. Turkey Eggs - these are larger than chicken eggs and have a richer flavor. They are not as commonly consumed as chicken eggs.

Menstrual Cycle: Follicular Phase

The follicular phase is the first phase of the menstrual cycle. It starts on the first day of menstruation and lasts for approximately 14 days. During this phase, follicle-stimulating hormone (FSH) is released from the pituitary gland, which stimulates the growth of follicles in the ovaries. Each follicle contains an egg.

As the follicles grow, they produce estrogen, which thickens the lining of the uterus in preparation for a potential pregnancy. As the follicles continue to grow, one dominant follicle will emerge and release its egg into the fallopian tube, which is called ovulation.

If the egg is not fertilized, the follicular phase will end, and the luteal phase will begin, leading to menstruation. However, if the egg is fertilized, it will implant in the uterus, and a pregnancy will begin.
