The main hormone of the postovulatory phase is
(a) Progesterone
(b) Estradiol
(c) Estrogen
(d) Luteinizing hormone

검증된 단계별 안내

Understand the phases of the menstrual cycle: the follicular (preovulatory) phase, ovulation, and the luteal (postovulatory) phase.

Recall that the postovulatory phase, also known as the luteal phase, occurs after ovulation when the corpus luteum forms from the ruptured follicle.

Identify the hormone primarily secreted by the corpus luteum during the luteal phase, which prepares the uterus for possible pregnancy.

Recognize that progesterone is the main hormone of the postovulatory phase because it maintains the uterine lining and supports early pregnancy.

Conclude that among the options given, progesterone (option a) is the correct hormone associated with the postovulatory phase.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Postovulatory Phase

The postovulatory phase, also known as the luteal phase, occurs after ovulation and before menstruation. During this phase, the body prepares the uterus for possible pregnancy, and hormone levels change to support this process.

Progesterone

Progesterone is the primary hormone produced by the corpus luteum during the postovulatory phase. It helps maintain the uterine lining for potential embryo implantation and inhibits further ovulation during this cycle.

Role of Luteinizing Hormone (LH)

Luteinizing hormone triggers ovulation and the formation of the corpus luteum. Although LH peaks just before ovulation, its levels decline during the postovulatory phase, making it less dominant compared to progesterone.
