$\huge\fcolorbox{aqua}{aqua}{\underline{Explanation !}}$

• Human chorionic gonadotropin (hCG) :

hCG is an important hormone in early pregnancy. It’s produced by the placenta after implantation, and supports the function of the corpus luteum. The corpus luteum is a temporary structure in the ovaries which produces other key hormones during early pregnancy.

• Progesterone :

During the early weeks of pregnancy, the corpus luteum produces progesterone. After 8-12 weeks, the placenta takes over.Progesterone stimulates growth of the blood vessels that supply the womb lining. It also stimulates the lining to release nutrients, providing nourishment for the early embryo. Additionally, progesterone inhibits contraction of the smooth muscle of the uterus so that it grows as the baby does.

• Oestrogen :

As with progesterone, the corpus luteum produces oestrogen in the early stages of pregnancy before the placenta takes over. Oestrogen is actually a collective group of similar compounds: oestrone, oestradiol, and oestriol.Oestrogen helps the uterus grow and maintains its lining. It supports foetal development, including the development of organs and bodily systems. It also activates and regulates the production of other important pregnancy hormones.

• Prolactin :

Prolactin is the main hormone needed to trigger the production of breast milk. It enlarges the mammary glands to prepare for this (though as previously noted progesterone levels prevent lactation until the baby is born).Prolactin has other roles unrelated to milk production. It contributes to the development of the foetal lungs and brain, and also to the mother’s immune system tolerating the foetus.

• Relaxin :

Relaxin levels are highest during the first trimester of pregnancy, but it is present throughout. It has several roles, including prohibiting contraction of the uterine muscles to prevent premature birth.Relaxin also helps the mother’s body prepare for birth. It relaxes joints in the pelvis and softens and widens the cervix to make delivery of the baby easier.

• Oxytocin :

Oxytocin only appears in significant amounts towards the end of pregnancy, though it is present in lower amounts before this. Its levels rise when labour starts, triggering contractions.
