We are super-excited to redesign and re-introduce this fluffy friend to you after a long-overdue makeover. We first put our mammary gland out there in 2009 and the response was…underwhelming. Let’s just say we thought people liked mammary glands, but really what y’all actually wanted was boobs. We get it. Everyone likes boobs, right? We hope you like this one! Now you’ve got something fun to give the bravest and most amazing breast cancer survivor in your life.

Your breasts contain fat, muscle, nipples, and mammary glands, which look like a bunch of grapes (see picture below) and can produce milk to feed babies. Mammary glands are what give mammals their name. Both women and men have mammary glands. The hormone estrogen promotes breast development, while testosterone inhibits breasts. It’s the breast of both worlds! Measures a highly unrealistic 7" x 9" x 6”.

Don’t let cancer get the breast of you! Do your best to check your breasts, no one knows them better than you. 🎀

Relaxin is a polypeptide hormone released by the corpus luteum (ovary), uterus, placenta and mammary gland. It plays an important role in pregnancy and childbirth, but there's still much mystery around the function of this multi-tasking hormone. Some of what we do know is that relaxin prevents uterine contractions early in pregnancy to avoid premature childbirth. During childbirth, it helps the cervix dilate and the vagina to soften and widen. In blood circulation, levels of relaxin rise after ovulation and lower again if pregnancy does not occur.  

Relaxin has also been discovered in men, although its function is even more unclear in men. Secreted by the prostate, it is found in semen. It is thought to assist the movement of sperm cells in the semen.

Recent findings show that relaxin also decreases tissue fibrosis in the heart, lungs, kidney and liver. It supports the growth of new blood vessels, helps heal wounds and is anti-inflammatory. Even though researchers are still figuring out what exactly it does, relaxin seems to be a pivotal hormone in various systems of the body, aside from just reproductive. Cool!

Happy National Breastfeeding Month from Mammary Gland and her BFF Lux Baby Bottle!
