The Role of Estrogen in Male Breast Enlargement

There’s no denying the importance of estrogen in male breast enlargement.

As the primary female hormone, estrogen is the hormone most responsible for breast development as well as the development of secondary sex characteristics like the full hips and soft, hairless skin of women.

Because of the huge role estrogen plays, it is the most used hormone for male breast enlargement purposes. But does it work for men too?

How Does Estrogen Affect Male Breast Enlargement?

Estrogen is most known as being a female sex hormone, yet male bodies produce it as well. The only difference is that women produce a lot more of it. Estrogen and testosterone are similar in this way – both males and females produce both estrogen and testosterone.

But males tend to produce significantly less estrogen and more testosterone than females. Females also produce both estrogen and testosterone, but around 75% of the testosterone produced by the female body is automatically converted into estrogen by a process called aromatose.

Another similarity between the male and female body is the breast tissue. Although you wouldn’t guess it by comparing a full-grown man’s chest to a full-grown woman’s breasts, men and women have identical breast structure up until the time they hit puberty.

The thing that causes the differences between male and female chests beyond puberty is the fact that the female body starts pumping out estrogen. The increase in estrogen begins the feminizing process in the female body by sending signals to the receptors in the breast tissue cells to expand and develop the breast tissue.

The interesting thing is that men also have these estrogen receptors in their breast tissue too – they just don’t receive the same estrogen supply that causes them to develop. This is why estrogen-increasing breast enhancement pills have the same effect on men as they do on women – both genders have receptors, but it needs the estrogen to begin to develop.

What are the Estrogen Options for Male Breast Enhancement?

There are a few options of using estrogen for male breast enlargement purposes. Some are more risky and permanent than others – make sure you read through them and do your research before deciding on your own male breast enlargement method.

1. Hormone Replacement Therapy

One well-known option for men looking to grow female breasts is known as hormone replacement therapy (HRT). It’s a process by which male hormones are replaced with female hormones, such as estrogen, to cause the development of female secondary sex characteristics.

If you’re just looking toward estrogen for male breast enlargement purposes, we really don’t recommend HRT. It’s risks – such as blood clotting and heart failure – are much too high. HRT will cause your breasts to grow and your nipples to enlarge. It will also give you a more feminine distribution of body fat as well as more feminine skin – BUT it comes at the cost of permanent sterility as well as loss of sex drive and reduced testicle size.

If you are just looking to grow bigger male breasts, the risks of HRT are not worth it – there are other, safer options of male breast enlargement.

2. Herbal Breast Enhancement for Men

One such option is herbal breast enhancement. There is a wide variety of breast enhancement herbs that are rich in plant-based estrogen. These phytoestrogenic herbs, combined with anti androgen herbs to suppress testosterone, will supple the estrogen to increase your breasts without compromising your health or your ability to have sex and reproduce.

2a. Pueraria Mirifica for Men

An example of a very potent herb for male breast enlargement is a phytoestrogenic herb known as pueraria mirifica. Pueraria mirifica contains phytoestrogens known as Miroestrol and Deoxymiroestrol, which have the most potent phytoestrogenic activity due to their structural similarity to estradiol, which is the strongest of the estrogen hormones and the one most responsible for breast growth.

Albeit potent, plant-based estrogens don’t carry the same high risks as the synthetic hormones used in HRT and for this reason, we highly recommend them for male breast enlargement.

We recommend Ainterol for Pueraria Mirifica pills since they contain only 100% premium farmed cultivar in a concentrated form, which is important for you to experience the efficacy of pueraria mirifica. It is only the root of farmed pueraria mirifica that contains the potent phytoestrogens that boost breast size.

3. Bovine Ovary for Men

Yet another option for estrogen is bovine ovary pills. Bovine ovary is exactly what it sounds like – the ovaries of a cow. This method of breast enlargement is based on a centuries-old concept known as glandular therapy. It operates on the idea that like cures like.

Bovine ovary pills are different from herbal breast enhancement pills in that they do not contain estrogen of their own. Instead, the bovine ovary works by stimulating the pituitary gland, which is your body’s major hormone regulator, so that you can produce your own hormones. In men, bovine ovary pills begin to cause a process called aromatase, which occurs naturally in the female body.

It’s a process by which the body converts testosterone into estrogen. In around six months time, bovine ovary pills reprograms the way the male body processes hormones. Your breast become bigger and fuller, your hips widen and round out, your moods will change, and you might even smell different. This is why Bovine ovary is recommended only for men who desire to permanently become women.

After just around six months of use, your sperm count will be at levels near sterile. Please keep this in mind before taking bovine ovary pills for male breast enlargement.


Estrogen is necessary for breast development and you’ll have to make it a priority in your male breast enlargement method – BUT the estrogen options vary quite a lot. Please make sure you choose the estrogen option that suits your end goals and purposes!
