    Human Physiology/The female reproductive system 3 The ovaries of a newborn baby girl contain about one million oocytes. This number declines to , to , by the time puberty is reached. On average, oocytes are ovulated during a woman's reproductive lifetime. Female Genitalia The female sexual organs have reproductive and sexual functions and are divided into internal and external sexual organs. The external female genital (vulva, pudendum) reaches from the outside to the hymen. Some authors also consider the female urethra as an external female sexual organ. Urinary and genital apparatus are.

    Disorders of sex development (DSDs), also known as differences in sex development, diverse sex development and variations in sex characteristics (VSC), are medical conditions involving the reproductive specifically, these terms refer to "congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical.".   The female genital tract comprises the vulva, vagina, uterus, cervix, fallopian tubes and ovaries. Infections in this region are common. Many are relatively trivial, but pelvic inflammatory disease can cause infertility or serious intra-abdominal sepsis.

In males, it is produced by embryonic Sertoli cells and causes the loss of the paramesonephric (Mullerian) duct system that forms the internal female genital tract. In females, it is produced after puberty by follicle cells and suppresses the development of other primary follicles, thus restricting the number of follicles stimulated by FSH.

Abstract. Aim: To present all the available data on the stages of normal embryological development of the female genital and urinary description of the reviewed data: Current embryological knowledge shows that the mesonephric or Wolffian ducts and the female gubernaculum play a role as inductors for the adequate development and formation of the Müllerian ducts.

Bacteria colonize most of the human body, and the female genital tract is not an exception. While the existence of a vaginal microbiota has been well established, the upper genital tract has been considered a sterile environment, with a general assumption that bacterial presence is associated with adverse clinical manifestation.

However, recent metagenomic studies identified specific patterns. This chapter covers the anomalies of female genital system, including anomalies of the ovarian, uterine tubes, uterus, genital tract, and vaginal.

Ectopic ovary is a rare gynecological anomaly in which the ectopic tissue can be adjacent to the normal ovary or in the pelvis, peritoneum, or retroperitoneum.

Acién P. The embryology of the genital tract and urinary system is described, and the hypothesis is advanced that the vagina is an organ embryologically derived from the mesonephric or Wolffian ducts in addition to the Müllerian tubercle.

The development of the normal female reproductive tract is a complex process. The indifferent gonad differentiates to the ovary.

The mesonephros, Wolffian and Mullerian ducts differentiate in an orchestrated manner to form the uterus, vagina and lower urinary tract. Disordered differentiation can result in congenital abnormalities affecting the female reproductive tracts, renal tract and lower. Which of the following statement is NOT correct regarding the development of female genital organs.

Ovaries developed from urogenital ridge. Rete ovarii is the embryonic remnant of mesonephricduct. Upper third and lower third of vagina are derived from different embryonic structures. Wolffian ducts fused to form the uterine body.

Key Terms. clitoris: a small sensitive elongated erectile organ at the anterior part of the vulva in female mammals, homologous with the penis; ovary: a female reproductive organ, often paired, that produces ova and in mammals secretes the hormones estrogen and progesterone; vagina: the passage leading from the opening of the vulva to the cervix of the uterus for copulation and childbirth.

Reproductive tract infections (RTIs) include three types of infection: 1) sexually transmitted diseases (STDs), such as chlamydia, gonorrhea, chancroid, and human immunodeficiency virus (HIV); 2) endogenous infections, which are caused by overgrowth of organisms normally present in the genital tract.This section focuses on the development of human embryos, with emphasis on the mechanisms underlying the development of the tissues and organs of the human body.

Harvard Book .Observations on the bacteriology and response to antibiotics of 15 women with severe post-operative infections of the genital tract suggest that anaerobic as well as aerobic organisms are important as the cause of sepsis.

Semi-synthetic penicillins, cephalosporins and aminoglycosides proved generally ineffective and the authors recommend a 2- or 3-drug regimen based on thiam-phenicol.
