In events of ovarian cycle, ovulation occurs before:
Correct answer: B. Formation of early corpus Iuteum
- A. Maturation of follicle
- B. Formation of early corpus Iuteum
- C. Regression of corpus luteum
- D. Development of follicle
Explanation
Ovulation occurs before the luteal phase of the ovarian cycle.The ovarian cycle is a monthly cycle that prepares the body for pregnancy. It is divided into two phases: the follicular phase and the luteal phase.The follicular phase begins with the menstrual period and ends with ovulation. During the follicular phase, the ovaries produce a mature egg. This process is controlled by hormones, including follicle-stimulating hormone (FSH) and luteinizing hormone (LH).Ovulation is the release of the mature egg from the ovary. It usually occurs 14 days before the next menstrual period. After ovulation, the empty follicle becomes the corpus luteum. The corpus luteum produces progesterone, which helps to prepare the uterus for pregnancy.The luteal phase begins after ovulation and ends with the onset of the next menstrual period. During the luteal phase, the corpus luteum continues to produce progesterone. If the egg is not fertilized, the corpus luteum will eventually degenerate and the levels of progesterone will decline. This will trigger the onset of the next menstrual period. So option B is correct.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
