Lecture 13: Ovulation and Inflammatory Reactions in the Follicular Phase

These flashcards cover key concepts about ovulation, inflammatory responses, hormonal changes, and the types of ovulators, among others.

What are the cardinal signs of inflammation?

Heat, redness, swelling, pain, and loss of function.

What triggers the preovulatory LH surge?

Histamine and increased levels of PGE2 and PGF2α.

What role does collagenase play in ovulation?

It breaks down the tunica albuginea connective tissue, allowing the follicle to rupture.

Define spontaneous ovulators.

Animals that ovulate with regular frequency in response to hormonal changes, such as cows and primates.

What is the effect of GnRH in estrus synchronization?

assists in the acceleration of estrus.

What is the significance of the stigma in ovulation?

The stigma forms when the follicular apex weakens and pushes outward due to increased follicular fluid.

How does the hormone PGF2α affect ovarian contractions?

PGF2α increases contractions of ovarian smooth muscle.

What happens to the follicular wall during ovulation?

It weakens due to increased follicular pressure and release of lysosomal enzymes.

What is the function of the zona pellucida in oocyte maturation?

It is essential for oocyte survival and fertilization, formed by the oocyte during the follicle stage.

How does immunity relate to fertility drugs?

Fertility drugs may induce an immune reaction affecting the development and function of reproductive hormones.
