Question

Ovulation in humans is controlled by:
A. FSH and LTH
B. FSH and GH
C. LTH and LH
D. FSH and LH

Answer 1

Hint: Ovarian cycle is the menstrual cycle event that occurs in the ovaries. Menstrual cycles in females begin when they reach puberty, and they include the follicular, ovulatory, and luteal phases. Menarche and menopause are terms used to describe the beginning and end of the menstrual cycle, respectively.

Complete Step by Step Answer:
Ovulation is the process through which a developed egg emerges from one of a female's ovaries. Oestrogen and progesterone, the female sex hormones, interact to cause the process of ovulation. Oestrogen levels rise just before the ovulation process. A spike in the level of luteinizing hormone produced by the pituitary gland triggers ovulation. The ovum, which is covered in a layer of granulosa cells, separates from the follicle as it leaves the ovary.

When a sperm is present, the fimbriae at the end of the oviduct pick up the ovum and transfer it to the fallopian tube, where fertilisation occurs and the zygote descends to the uterus where it is implanted in the uterine wall. The ovum deteriorates when there is no sperm present. The uterine wall thickens in response to the ovum's development phase and prepares for implantation. Menstruation results from the uterine endometrium being shed if there is no implantation. The menstrual cycle is a 28-day cycle in which this procedure is repeated. Oestrogen and progesterone from the ovaries, FSH and LH from the pituitary gland, and oestrogen and progesterone from the ovaries are the main hormones involved in the cycle.
Hence, the correct option is D. FSH and LH

Note: Ovulation causes ovum, which are formed in the ovaries, to be released. If sperm are present, the ovum is fertilised; otherwise, it disintegrates. The uterus then sheds its lining as a result. The menstrual cycle is the term used to describe this cycle. Birth control medications and breastfeeding can both inhibit the ovulation process in women.
