First, manual traction: girlhood is an important period for breast development, and it is also an important period for correcting nipple invagination. Often pulling the nipple can make the breast protrude, increase the supporting force of the surrounding skin, and play the role of "shaping". Several times a day. After a long time, the nipple naturally protrudes outward. If you can't pull it out, you can first push the skin near the nipple of the breast outward.

Second, breast pump therapy: after pregnancy, apply a breast pump to suck the nipple several times a day, and use its negative pressure to promote nipple swelling.

Thirdly, nipple orthosis is used to treat flat or sunken nipples.

Fourthly, mild primary nipple invagination can be treated conservatively, such as negative pressure suction combined with nipple suction and manual traction. If you can't pull out the nipple by hand, you need surgery. Nipple invagination can be corrected by plastic surgery or nipple invagination appliance.

5. Nipple is a very important sexual sensitive point for women. Many women's sexual desire is achieved through nipple stimulation. Once the nipple is sunken, it is difficult to play an effective role in sexual stimulation, and even affect the man's sexual desire.
