Question

Menstrual flow occurs due to lack of which hormone?
A. Progesterone
B. FSH
C. Oxytocin
D. Vasopressin

Answer 1

Hormones are chemical messengers that are secreted directly into the blood that brings them to the organs and tissues of the body to fulfil their functions. There are several types of hormones that work on various facets of body function and operation.

Complete Answer:
- Every month, one ovary releases an egg through a mechanism called ovulation. Around the same time, hormone shifts are preparing the uterus for birth. When ovulation happens and the egg is not fertilised, the lining of the uterus goes into the vagina. This is a time of menstruation.
- Progesterone is an ovarian-released hormone. Changing progesterone levels can lead to abnormal menstrual cycles and menopausal symptoms. Progesterone is also essential for the uterine implantation of the fertilised egg and for the continuation of pregnancy. Low progesterone can cause excessive uterine bleeding in women who are not pregnant.
- Irregular or missing cycles can mean malfunctioning ovaries and low progesterone. When you get pregnant, you will need progesterone to maintain your uterus before your baby is born.
- In women, the deficiency of follicle-stimulating hormone contributes to inadequate growth of puberty and poor ovarian function. In this case, ovarian follicles do not develop properly and may not release the egg, leading to infertility.
- If we're lacking in oxytocin, we're not going to feel as linked to others or feel as good about ourselves. The lack of oxytocin in the brain amygdala induces anxiety and panic.
- Vasopressin is a naturally occurring hormone that helps regulate different body functions. Vasopressin enables proper cellular activity by preserving the required amount of water in the space that covers cells within the body.

So, the correct answer is 'Option A- Progesterone'.

Note: Some disorders, such as elevated prolactin (a hormone that induces milk production), hypothyroidism, or polycystic ovarian syndrome (PCOS), can cause infrequent or absent ovulation, contributing to low progesterone levels.
