Which hormone is secreted by the corpus luteum during pregnancy?
Show Hint
• Estrogen \(\rightarrow\) follicle development
• Progesterone \(\rightarrow\) maintenance of pregnancy
• Relaxin \(\rightarrow\) relaxation of pelvic ligaments
- Estrogen only
- Progesterone only
- Progesterone and relaxin
- Testosterone
The Correct Option is C
Solution and Explanation
Step 1: Hormones secreted by corpus luteum. Corpus luteum secretes:
• progesterone
• relaxin These hormones help maintain pregnancy.
Step 2: Role of progesterone. Progesterone:
• maintains endometrium
• supports implantation
• prevents menstruation Final Answer: \[ \boxed{(C)\ \text{Progesterone and relaxin}} \]

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.
