Which organ of the body produces estrogen and progesterone?


Ovaries are part of the female reproductive system and are responsible for the production of estrogen and progesterone. They produce egg cells (ova-producing organs) and are at the helm of maintaining a healthy reproductive system in females. Ovaries and testes are called gonads which implies that they are the primary sex organs. Zeeva IVF clinic in Noida,

Along with performing the function of ova production, ovaries also play the role of acting like endocrine glands. This is because ovaries secrete hormones, specifically estrogen as well as progesterone. Estrogen and progesterone are extremely essential for reproductive development and fertility in females.

One of the answers to the question of how to increase progesterone to get pregnant is to reduce over-exercising. Progesterone as well as cortisol are derived from pregnenolone and are found in both hormones.

Things or activities that might lead up to stress in our body will cause adrenal glands to produce stress levels and put prime focus on our survival rather than any other functions in our body. Hence, when the patient questions the fact how to increase progesterone to get pregnant, doctors will merely suggest exercising. 

The production of cortisol takes precedence over sex hormones production when we exercise extensively. During this process, progesterone gets affected. 

The second answer to the question of how to increase progesterone to get pregnant is to avoid too much stress. Too much stress will lead to the secretion of adrenaline as well as cortisol at the expense of progesterone production. 


Ovaries are oval and are as large as a grape. They are found on the extreme ends of either side of the uterus (opposite ends of the pelvic wall). The tissue connecting the ovaries and the fallopian tube or oviduct is called fimbria, to which ovaries are attached. 


The two sex hormones released by ovaries are progesterone and estrogen. Three major types of estrogen are estradiol, estrone, as well as estriol. Together they work in unison and help with the healthy development of female sexual characteristics at the time of puberty, ensuring fertility. 

Estrogen contributes to the development of breasts in females and also regulates the distribution of fat in the hips, legs as well as breasts. It also plays a role in the development of reproductive organs.

Ovaries also release a hormone called relaxin just before giving birth. It secretes inhibin which signals the pituitary gland to inhibit the secretion of FSH (short for Follicle Stimulating Hormone).


Production and functions: Both progesterone, as well as estrogen, are highly essential for preparing the uterus for menstruation. The secretion of the same is signalled by the hypothalamus which is present in the basal part of the diencephalon, forebrain. 

After achieving puberty, the ovaries release an egg every month and this process is known as ovulation. The pituitary gland receives signals from the hypothalamus for the secretion of gonadotropin (FSH and LH). They are extremely important for the normal reproductive function which includes regulation of menstruation. 

The egg travels down the oviduct and progesterone is released. A temporary gland formed within the ovary secretes progesterone after ovulation. This gland is known as the corpus luteum. Progesterone thickens the wall of the uterus and prepares the body for pregnancy. The corpus luteum breaks down if the woman is not pregnant. 

On the other hand, if the woman gets pregnant, it will cause higher levels of estrogen and progesterone to be released. This will prevent any more eggs from maturing. It will also prevent uterine contractions and prepares the breasts for lactation. 

By the end of pregnancy, estrogen will send signals to the pituitary gland to release oxytocin. This will result in uterine contractions. Just before the delivery, relaxin is released by the ovaries which helps pelvic ligaments to loosen up for labour.
