Definition:
The breast is the upper ventral region of the torso of a primate, in left and right sides, which in a female contains the mammary gland that secretes milk used to feed infant.
Both men and women develop breasts from the same embryological tissues. However, at puberty, female sex hormones, mainly estrogen, promote breast development, which does not occur in men, due to the higher amount of testosterone. As a result, women's breasts become far more prominent than those of men.
Sexual Characteristics:
In some cultures breasts play a role in human sexual activity. Breasts and especially the nipple are one of a woman's erogenous zones. They are sensitive to the touch as they have many nerve endings; and it is common to press or massage them with hands or orally before or during sexual activity. Some women can achieve an orgasm from such activities. Research has suggested that the sensations are genital orgasms caused by nipple stimulation, and may also be directly linked to "the genital area of the brain". Sensation from the nipples travels to the same part of the brain as sensations from the vagina, clitoris and cervix. Nipple stimulation may trigger uterine contractions, which then produce a sensation in the genital area of the brain. In the ancient Indian work the Kama Sutra, light scratching of the breasts with nails and biting with teeth are considered erotic. During sexual arousal, breast size increases, venous patterns across the breasts become more visible, and nipples harden. Compared to other primates, human breasts are proportionately large throughout adult females' lives. Some writers have suggested that they may have evolved as a visual signal of sexual maturity and fertility.Many people regard the female human body, of which breasts are an important aspect, to be aesthetically pleasing, as well as erotic. Research conducted at the Victoria University of Wellington showed that breasts are often the first thing men look at, and for a longer time than other body parts.
Tips for Breast Enhancement:
Breast Implant:
A breast implant is a medical prosthesis used to correct the size, form, and feel of a woman’s breast in post mastectomy breast reconstruction; for correcting congenital defects and deformities of the chest wall; for aesthetic breast augmentation; and for creating breasts in the male-to-female transsexual patient. There are three general types of breast implant device, defined by the filler material: saline, silicone, and composite. The saline implant has an Elastoplast silicone shell filled with sterile saline solution; the silicone implant has an Elastoplast silicone shell filled with viscous silicone gel; and the alternative composition implants featured miscellaneous fillers, such as soy oil, polypropylene string, etc. In surgical practice, for the reconstruction of a breast, the tissue expander device is a temporary breast prosthesis used to form and establish an implant pocket for the permanent breast implant.
Types of Breast implant Devices:
There are three types of breast implant used for mammoplasty, breast reconstruction, and breast augmentation procedures
- saline implant filled with sterile saline solution.
- silicone implant filled with viscous silicone gel.
- alternative-composition implant with miscellaneous fillers e.g. soy oil, polypropylene string, etc. that are no longer manufactured.
Scientific explanation:
Some scientists have hypothesized that sexual attraction towards breasts is the result of their function as a secondary sex characteristics. For instance, British zoologist and ethologist Desmond Morris theorizes that cleavage is a sexual signal that imitates the image of the cleft between the buttocks, which according to Morris in The Naked Ape is also unique to humans, other primates as a rule having much flatter buttocks. Evolutionary Psychologists theorize that humans' permanently enlarged breasts, in contrast to other primates' breasts, which only enlarge during ovulation, allows females to "solicit male attention and investment even when they are not really fertile".
