In 1999, Whipple and Komisaruk proposed cervix stimulation as being able to cause a fourth type of female orgasm.Female orgasms by means other than clitoral or vaginal/G-spot stimulation are less prevalent in scientific literature and most scientists contend that no distinction should be made between "types" of female orgasm. This distinction began with Sigmund Freud, who postulated the concept of "vaginal orgasm" as separate from clitoral orgasm. In 1905, Freud stated that clitoral orgasms are purely an adolescent phenomenon and that upon reaching puberty, the proper response of mature women is a change-over to vaginal orgasms, meaning orgasms without any clitoral stimulation. While Freud provided no evidence for this basic assumption, the consequences of this theory were considerable. Many women felt inadequate when they could not achieve orgasm via vaginal intercourse alone, involving little or no clitoral stimulation, as Freuds theory made penile-vaginal intercourse the central component to womens sexual satisfaction.The first major national surveys of sexual behavior were the Kinsey Reports. Alfred Kinsey was the first researcher to harshly criticize Freuds ideas about female sexuality and orgasm when, through his interviews with thousands of women, Kinsey found that most of the women he surveyed could not have vaginal orgasms. He "criticized Freud and other theorists for projecting male constructs of sexuality onto women" and "viewed the clitoris as the main center of sexual response" and the vagina as "relatively unimportant" for sexual satisfaction, relaying that "few women inserted fingers or objects into their vaginas when they masturbated".
The most perceptible sign of testicular atrophy is shrinkage of the testicle(s).Signs and symptoms before puberty include:

lack of development of pubic hair
lack of development of facial hair
lack of penis growth
lower testosteroneTestosterone is a hormone that is found primarily in a portion of the male-assigned reproductive system called the testes and is normally measured in nanograms per deciliter. Testosterone is in charge of the growth and production of many sexual attributes in people with testes, including facial hair, pubic hair, penis size, vocal and muscle mass changes, regulation of sex drive, and sperm production. Normal testosterone levels in people with testes who have not yet hit puberty are less than 20 nanograms per deciliter. Low testosterone can be defined as hypogonadism in people with testes. Hypogonadism in people with testes is established as the hormonal inhibition of testosterone that can either be inherited or acquired at a later stage in life. Under the circumstances of pre-pubescent hypogonadism, many sexual developmental characteristics may be altered. Testosterone affects hair growth by regulating the follicle itself, which in turn affects the specific growth phases of the hair follicle. As a person with testes hits puberty, androgen, a steroid sex hormone, is produced at an increased rate, which creates terminal hair follicles. Terminal hair follicles create thicker and more pigmented hair which is also regulated by testosterone production. Testosterone also impacts pre-pubescent penis size by providing penile tissue with girth and density. The drop in testosterone values is mainly due to significant impairment of Leydig cells brought upon by hypogonadism.
