Question:
Read the following passage carefully and answer the question that follows:
During the menstrual cycle, the endometrium undergoes cyclic changes under the influence of hormones. Ovulation generally occurs around the 14th day of a 28-day menstrual cycle. After ovulation, the ruptured Graafian follicle transforms into a temporary endocrine gland known as corpus luteum. If fertilisation does not occur, the corpus luteum degenerates leading to menstruation.
Which hormone is mainly responsible for maintaining the endometrium after ovulation?

Which hormone is mainly responsible for maintaining the endometrium after ovulation?
Show Hint
Corpus luteum = Progesterone secretion. This is one of the most important biology facts for CUET and NEET.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
After ovulation, the ruptured Graafian follicle converts into corpus luteum which secretes progesterone.
Step 1: Understanding the role of corpus luteum.
Corpus luteum acts as a temporary endocrine gland.
Step 2: Hormone secreted by corpus luteum.
The corpus luteum mainly secretes: \[ \text{Progesterone} \]
Step 3: Function of progesterone.
Progesterone:
Step 4: Identifying the correct option.
Hence, progesterone is the correct answer.
Step 1: Understanding the role of corpus luteum.
Corpus luteum acts as a temporary endocrine gland.
Step 2: Hormone secreted by corpus luteum.
The corpus luteum mainly secretes: \[ \text{Progesterone} \]
Step 3: Function of progesterone.
Progesterone:
- Maintains the endometrium
- Prepares uterus for implantation
- Supports early pregnancy
Step 4: Identifying the correct option.
Hence, progesterone is the correct answer.

Top CUET Human Reproduction Questions
- Humans are sexually reproducing and viviparous. The male reproductive system is composed of a pair of testes, the male sex accessory ducts, the accessory glands, and external genitalia. The female reproductive system consists of a pair of ovaries, a pair of oviducts, a uterus, a vagina, external genitalia, and a pair of mammary glands. The reproductive cycle of female primates is called the menstrual cycle. The menstrual cycle starts only after attaining sexual maturation (puberty). Coitus followed by fertilization leads to the formation of a zygote. After 9 months of pregnancy, the fully developed foetus is ready for delivery.
- Sex in human embryos is determined by:
- Arrange the following stages of oogenesis in order of their occurrence:
(A) Ovum
(B) Oogonia
(C) Primary oocyte
(D) Secondary oocyte
Choose the correct answer from the options given below: Arrange the following events in the correct order pertaining to fertilization in the human reproductive system.
(A) The blastocyst becomes embedded in the endometrium.
(B) Finger-like projections appear on the trophoblast called chorionic villi.
(C) The blastomeres are arranged into trophoblast and the inner cell mass.
(D) The zygote divides mitotically and transforms into an embryo with 8-16 blastomeres, called a morula.
