A sex organ is any part of an animal's body, involved in sexual reproduction. The reproductive organs together constitute the reproductive system; the testis in the male, the ovary in the female, are called the primary sex organs. All others are called secondary sex organs, divided between the external sex organs—the genitals or genitalia, visible at birth in both sexes—and the internal sex organs. Mosses and some similar plants have gametangia for reproductive organs, which are part of the gametophyte; the flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants produce their sexually reproductive structures within the gametophytes contained within the cones and pollen; the cones and pollen are not themselves sexual organs. The primary sex organs are the gonads, a pair of sex organs the testes in the male or the ovaries in the female; as primary sex organs, gonads generate reproductive gametes containing inheritable DNA.

They produce most of the primary hormones that affect sexual development, regulate other sexual organs and sexually differentiated behaviors. Secondary sex organs refer the rest of the reproductive system, whether external; the Latin term genitalia, sometimes anglicized as genitals, is used to describe the externally visible sex organs: in male mammals, the penis and scrotum. In general zoology, given the great variety in organs and behaviors involved in copulation, male genitalia are more defined as "all male structures that are inserted in the female or that hold her near her gonopore during sperm transfer"; the visible portion of the mammalian genitals for males penis. In placental mammals, females have two genital orifices, the vagina and urethra, while males have only one, the urethra. Male and female genitals have many nerve endings, resulting in pleasurable and sensitive touch. In most human societies in conservative ones, exposure of the genitals is considered a public indecency. In mammals, sex organs include: In typical prenatal development, sex organs originate from a common primordium during early gestation and differentiate into male or female sexes.

The SRY gene located on the Y chromosome and encoding the testis determining factor, determines the direction of this differentiation. The absence of it allows the gonads to continue to develop into ovaries. Thereafter, the development of the internal, external reproductive organs is determined by hormones produced by certain fetal gonads and the cells' response to them; the initial appearance of the fetal genitalia looks feminine: a pair of "urogenital folds" with a small protuberance in the middle, the urethra behind the protuberance. If the fetus has testes, if the testes produce testosterone, if the cells of the genitals respond to the testosterone, the outer urogenital folds swell and fuse in the midline to produce the scrotum; each sex organ in one sex has a homologous counterpart in the other one. See a list of homologues of the human reproductive system. In a larger perspective, the whole process of sexual differentiation includes development of secondary sexual characteristics such as patterns of pubic and facial hair and female breasts that emerge at puberty.

Furthermore, differences in brain structure arise, but not determining, behavior. Intersex is the development of genitalia somewhere between typical male and female genitalia. Once the child is born, the parents are faced with decisions that are difficult to make, such as whether or not to modify the genitalia, assign the child as male or female, or leave the genitalia as is; some parents allow their doctors to choose. If they do decide to modify the genitalia, they have a 50% chance of getting genitalia that will match the child's gender identity. If they pick the wrong one, their child may begin to show symptoms of transsexualism, which can lead them to a life of discomfort until they are able to remedy the issue; because of the strong sexual selection affecting the structure and function of genitalia, they form an organ system that evolves rapidly. A great variety of genital form and function may therefore be found among animals. In many other animals a single posterior orifice, called the cloaca, serves as the only opening for the reproductive and urinary tracts.

All amphibians, reptiles, some fish, a few mammals have this orifice, from which they excrete both urine and feces in addition to serving reproductive functions. Excretory systems with analogous purpose in certain invertebrates are sometimes referred to as cloacae; the organs concerned with insect mating and the deposition of eggs are known collectively as the external genitalia, although they may be internal. The reproductive system of gastropods varies from one group to another. Planaria are flat worms used in biological research. There are asexual planaria. Sexual planaria are hermaphrodites, possessing both ovaries. Eac

National Auditorium is an entertainment center at Paseo de la Reforma #50, Chapultepec in Mexico City. The National Auditorium is considered among the world's best venues by specialized media, it was designed by Mexican architects Pedro Ramírez Vázquez and Gonzalo Ramírez del Sordo, remodeled by Abraham Zabludovsky and Teodoro González de León. There are concerts, theatre and more, it has a small venue available for smaller events, called Auditorio Lunario. The total seating capacity of 10,000. Constructed in 1952, it was used for volleyball and basketball matches of the 1954 Central American and Caribbean Games and had seen performances of the San Francisco Ballet and New York Philharmonic in 1958; the auditorium was the venue for the gymnastics events at the 1968 Summer Olympics. Since the 1970s, it has been used for international music, song and film festivals and exhibitions. From 1988 to 1990, the auditorium went through an 18-months-long renovation, designed by architects Abraham Zaludovsky and Teodoro Gonzalez de Leon, which brought it to the current design.

It hosted the 2007 Miss Universe pageants. In 2007, the American magazine Pollstar made the National Auditorium a nominee for International Theatre of the Year. In November 2007, the Auditorio Nacional won the Billboard Touring Award for best concert venue under 10,000 seats. Auditorio Nacional houses the largest pipe organ in Latin America. In 2016, it hosted the premiere of the anticipated comic-book film, Batman v Superman: Dawn of Justice. 1968 Summer Olympics official report. Volume 2. Part 1. P. 77. Official website

Robert Daniel Scinto is a Connecticut commercial real estate developer, founder, chief executive officer and chairman of the board of R. D. Scinto, Inc. Shelton. Scinto was born in Bridgeport, February 16, 1947, the son of Daniel Scinto and Doxie Andrews Scinto, he graduated from Andrew Warde High School in Fairfield in 1965 and attended Sacred Heart University in Fairfield at night, graduating in 1971 with a bachelor of arts degree in business administration. While attending Sacred Heart University, Robert Scinto worked by day as a plumber in his father's business, D and R Plumbing, in Bridgeport, his initial rehabilitation project was of a three-family house in Bridgeport, the first of some 20 rehabs he undertook between 1971 and 1975. In 1975, R. D. Scinto, Inc. i77constructed its first apartment house, a 22-unit structure at 300 French St. in Bridgeport. The second, a 39-unit apartment house in Bridgeport, went up in 1979. In the same year he began initiating projects in Shelton, beginning with construction of the State National Bank building in that community.

Incremental and steady growth has characterized R. D. Scinto, Inc. over the years. Scinto properties can be found in Trumbull, Fairfield and Naugatuck, as well as Shelton. Scinto has been renowned as a vital structure in many of the communities. For example, countless supporters attended his 2011 hearing when he was accused of making false statements to an FBI agent in 2008 Scinto was sentenced to six months after pleading guilty, though still he remains a dedicated and vital part of his area. Scinto has bounced back headfirst into his business, has been spearheading many exciting new projects; the most recent is the Medical Center of Fairfield County in Trumbull, which opened in March, 2013. The state-of-the-art facility is home to the Surgery Center of Fairfield County, replete with surgical suites, recovery bays and offices for physicians and medical personnel; the 34 buildings in the R. D. Scinto, Inc. network include 3.2 million square feet of office space. Ninetyeight percent is occupied.

It is now a $200 million corporation. The centerpiece of Scinto's enterprise is the 65-acre campus on Corporate Drive in Shelton, whose 11 buildings are home to an array of corporate entities, including Cartier, Prudential Financial, Iriquois Gas, Blum Shapiro and Ganim Financial. Situated among the buildings is Scinto's Il Palio Ristorante, named for the famed medieval horse race held twice annually in Siena, Italy. Among the pieces of art displayed on the Shelton campus are copies of two classic sculptures: a soaring rendition of Michelangelo's "David," and a dramatic interpretive rendering of Leonardo da Vinci's "Vitruvian Man" by noted American sculptor Babette Bloch. At the dedication of the latter, art historian Dr. Philip Eliasoph of Fairfield University dubbed Scinto "Roberto da Shelton, or Roberto Prince of Fairfield County". William Shakespeare has a home on the campus. Tuesday evenings find lovers of the Bard filling the campus auditorium for presentations on his works in a series called Nights With Shakespeare.

The series was prompted by Barbara Scinto's fascination with the classics. Scinto has received the Distinguished Achievement Award from the Connecticut Construction Institute, the Bridgeport Rescue Mission Award for helping the homeless, the Patron of the Year Award from the Fairfield Arts Council, the Kennedy Center Vision Award, the Toby Award of the Southern Connecticut Building Owners and Management Association, among others.
