We cannot escape from hearing the word “hormones” when we are talking about body systems and processes. Before we try to dig fertility hormones, let us try to define first what they are.

What are Hormones?

Hormones are considered to be our body’s communication network. It is usually released by a specific gland and it travels through the circulatory system- the blood, where it will find a cell with a receptor where it will perfectly fit. After which, these cells will be receiving signals from the master gland which is the hypothalamus to be able to perform its own function.

Fertility Hormones

Follicle Stimulating Hormone (FSH)

This plays an important role in fertility. FSH is an ovarian hormone, which means it directly acts on that specific reproductive organ. It allows the ovaries to continuously produce mature egg for fertilization. One egg equals one follicle which works together to be able to produce another essential hormone, estrogen.


As early as adolescence period, this hormone has been identified in bringing about bodily changes such as eruption of breast buds, menarche or the onset of menstruation, widening of the pelvic diameter, among others, which are all needed in preparation for giving birth.

Estrogens are present in both sexes but the levels are significantly higher in women. Essential functions of estrogen involve the following:

  • Activation of female secondary sex characteristics, as mentioned
  • Body metabolism
  • Growth and stimulation of uterus
  • Thickening of vaginal wall and vaginal lubrication
  • Increasing bone formation
  • Improves coagulation
  • Synthetic estrogen is used as a form of contraception & hormonal replacement therapy to prevent post menopausal diseases


Progesterone is a precursor of estrogen.This hormone is necessary for the survival of the fertilized ovum resulting to a fetus all throughout the mother’s gestation. Other functions of progesterone includes:

  • Maintains intactness of uterus
  • Thermogenic or temperature raising effect
  • Protects against various forms of cellular aberration or cancer
  • Natural diuretic and antidepressant
  •  Normalizes blood clotting
  • Helps balance thyroid hormones

Human Placental Lactogen (HPL)

Also called human chorionic somatomammotropin, the function of HPL mimics one which is the growth hormone. It neutralizes the state of metabolism during pregnancy and facilitates the supply of energy and nutrients to the fetus.


A mammalian hormone known to be acting primarily as a neurotransmitter in the brain. On the other hand it is more popular when linked to female reproduction. It facilitates birth as it stimulates the uterus to contract and more importantly, it is responsible for the ejection of milk during lactation that’s why medical practitioners call it as the “cuddle hormone”Experts also have mentioned that oxytocin has something to do with orgasm, pair bonding and maternal behaviours.

All these hormones are of great importance to a woman. They may have specific function but trying to scrutinize it, they are highly interrelated: nourishing, maintaining and protecting not only the female reproductive organs but also the other systems of the body.
