Hint: The female reproductive system consists of primary sex organ known as ovary. There is an ovary found on each side of the body. Ovaries are the primary female sex organs that produce the female gamete known as ovum or egg and several steroid hormones. Each ovary is about 2-4 cm in length.
Complete answer:
- The ovary is a primary female sex organ found in each side of the lower abdomen.
- Ovulation: Ovulation is the release of the ovum or egg from one of the female’s ovaries.
- After the release of egg, egg travels down to the fallopian tube where fertilization may occur with sperm.
- It typically lasts for one day and occurs in the middle of women’s menstrual cycle.
- Ovulation is followed by the luteal phase during which the remaining parts of the graafian follicle gets converted into corpus luteum.
- Corpus luteum secretes progesterone which is necessary for the maintenance of the endometrial lining.
- FSH known as Follicle stimulating hormone which is released from the anterior part of pituitary gland help in stimulating the growth of the ovarian follicles.
> LH or luteinizing Hormone stimulates growth of ovarian follicles in females. Hence, it is responsible for ovulation and formation of corpus luteum.
> Luteotropic hormone or Prolactin is also known as lactogenic hormone is produced by the pituitary gland. This hormone stimulates the production of milk in mammary glands during pregnancy.
> ICSH or Interstitial cell stimulating hormone is luteinizing hormone found in the males and it further affects the Leydig cells of testes.
Hence, the correct answer is option (B).
Note: Menstrual cycle: The reproductive cycle in the female primates is known as menstrual cycle.
Menarche: It is the starting of the menstrual cycle.
Menopause: It is the ceases of the menstrual cycle usually occurs at the age of 50 years.
Various events of menstrual cycle are:
- Menstrual phase
- Follicular phase
- Ovulatory phase
- Luteal phase
