Turner syndrome Turner syndrome is a genetic disease in which all or part of one X chromosome is missing, resulting in X females or partially XX females. It occours in 1 of every 2.000-2.500 females born. The common anomalies of Turner syndrome include short stature, epicanthal folds, low nuchal hair line, shield-like chest, webbed neck, high arched palate, coarctation of the aorta, ventricular septal defect, renal anomalies, pigmented nevi, lymphedema, hypoplastic nails and inverted nipples.

Male Infertility Overview Assessment, Diagnosis, and Treatment Stephen F. Shaban, M.D. Clinical Assistant Professor Department of Surgery, Division of Urology University of North Carolina School of Medicine Chapel Hill, NC. ASSESSMENT Male Infertility - Overview Approximately 15% of couples attempting their first pregnancy meet with failure. Most authorities define these patients as primarily infertile if they have been unable to achieve a pregnancy after one year of unprotected intercourse. Conception normally is achieved within twelve months in 80-85% of couples who use no contraceptive measures, and persons presenting after this time should therefore be regarded as possibly infertile and should be evaluated. Data available over the past twenty years reveal that in approximately 30% of cases pathology is found in the man alone, and in another 20% both the man and woman are abnormal. Therefore, the male factor is at least partly responsible in about 50% of infertile couples. MALE REPRODUCTIVE PHYSIOLOGY The Hypothalamic-Pituitary-Gonadal Axis The hypothalamus is the integrative center of the reproductive axis and receives messages from both the central nervous system and the testes to regulate the production and secretion of gonadotropin releasing hormone (GnRH) . Neurotransmitters and neuropeptides have both inhibitory and stipulatory influence on the hypothalamus. The hypothalamus releases GnRH in a pulsatile nature which appears to be essential for stimulating the production and release of both

Endocrinology and Turner Syndrome Why is it important to know about Turner Syndrome? Turner syndrome can cause physiologic and psychological problems that can affect normal development and maturation in females, even if it is not usually life-threatening. Effective treatment is available to minimize some of these effects and reduce many of the associated symptoms, if it is started soon enough. It is important to identify those with Turner syndrome early so that treatment can begin and promote normal growth and development as girls enter puberty. What is Turner Syndrome? Turner syndrome occurs in females when one of the X (female) chromosomes is missing or damaged. Typically, females have two X chromosomes (XX). These chromosomes not only determine the sex of a person but also have other influences. Sexual definition affects physiologic growth and development as well psychological development. The most common features of Turner syndrome are short stature and reduced or absent development of the ovaries. As adults, women with this disorder are typically infertile. Other complications of Turner syndrome include defects of the kidneys and/or heart, thyroid disease, arthritis and skeletal disorders, and development of type 2 diabetes. As children, the onset of puberty is delayed if the disorder has not been identified and treatment begun. Such delays in sexual development may lead to poor social development and low self esteem. In addition, some girls may experience learning difficulties, particularly in the subject of mathematics. Problems such as underactive thyroid glands, abnormal liver function tests, a propensity to ear infections and hearing deficits, can also be seen. Symptoms may vary widely among those affected.

Gonadoblastoma is a rare benign tumor that has the potential for malignant transformation and affects a subset of patients with intersex disorders. The select intersex syndromes associated with a clear risk of developing gonadoblastoma are (1) complete androgen insensitivity/male pseudohermaphroditism (46,XY), (2) mixed gonadal dysgenesis (45,X/46,XY), and (3) a subset of patients with Turner syndrome (45,XO). The 2 essential findings that predispose these abnormal gonads to undergo neoplastic transformation into gonadoblastoma are (1) the karyotype has either macroscopic or molecular evidence of a Y chromosome and (2) the gonads nearly always are located intra-abdominally. Histologically, the following 2 distinct cell types characterize these tumors: (1) large germ cells (similar to dysgerminoma and seminoma) and (2) small cells, which resemble immature Sertoli or granulosa cells. Additionally, in two thirds of patients, Leydig-type cells are found in the stromal component of the tumor and are thought to be responsible for frequent virilizing features in these patients. While gonadoblastoma has normal germinal and stromal characteristics, some of the germ cells are large and have numerous mitotic figures that resemble classic testicular seminoma. In fact, as these cells overgrow the surrounding stroma, the tumor gains the characteristics of a more aggressive lesion and acquires the potential for metastatic spread.

Note: The hardcopy of the booklet contains additional diagrams and photos. Turner Syndrome INTRODUCTION There are many possible reasons why a child may grow slowly, including: hereditary factors (short parents), diseases affecting the kidneys; heart, lungs or intestines; hormone imbalances; severe stress or emotional deprivation; infections in the womb before birth; bone diseases; and genetic or chromosomal abnormalities. The purpose of this booklet is to examine one of the common genetic disorders associated with short stature. In 1938, Dr. Henry Turner recognized a pattern of short stature and incomplete sexual maturation in otherwise normal females. The common name for this condition is Turner syndrome, after Dr. Turner. A syndrome is a set of features often found in association with each other and believed to stem from the same cause. Turner syndrome is a genetic disorder that results from an abnormality of a chromosome. Chromosomes are thin strands of material found in the nucleus of each cell. They contain the genes that determine each person's characteristics. Every individual has 22 pairs of chromosomes and 1 pair of sex chromosomes (called X and Y). The sex chromosomes determine whether an individual is male or female; they influence height as well as development of sexual organs. A female ordinarily has 2 X chromosomes, while a male has one X and one Y chromosome.

Research Provides Hope for Turner Girls Turner Syndrome is one of the few genetic diseases that affects only females. Humans have 23 pairs of chromosomes, one set from each parent. One of these pairs of chromosomes - the sex chromosomes - determines whether you are male (XY) or female (XX). In Turner's, there is a total or partial loss of one of the sex chromosomes. Because a Y-chromosome cannot function on its own, males lacking a sex chromosome are not produced. The X-chromosome can survive on its own, however, and the result is a girl with Turner Syndrome (XO). Determining the cause of the condition was due to extensive research, and the numerous girls and women who participated in early Turner Syndrome clinical trials. Genetic research did not stop there, however. Today, the goal is to identify the genes responsible for the medical problems associated with the disease. These include a webbed neck, short stature, lack of sexual development, non-verbal learning disabilities, heart and kidney defects and, in adult women, high blood pressure, diabetes and osteoporosis. Research also evaluates the effects of drugs, including hormones, on these conditions. Reason's To Join a Turner Syndrome Clinical Trial One of the most common motives for participating in a Turner Syndrome clinical trial is gaining access to new treatments. Of course, the possibility of being in the group using a placebo may appear to be of little immediate benefit. However, the advice from experts on effectively coping with the disease can be invaluable. In addition, participants benefit from the free examinations and assessments associated with the study.

Turner syndrome From Wikipedia, the free encyclopedia. Turner syndrome is a human genetic abnormality , caused by a nondisjunction in the sex chromosomes that occur to females (1 out of every 2,500 births). Instead of the normal XX or XY sex chromosomes, only a single X chromosome is present. In Turner syndrome, female sexual characteristics are present but underdeveloped. People with Turner syndrome often have a short stature, webbed neck , low hairline, abnormal eye features and bone development and a "caved-in" appearance to the chest. Turner syndrome is a disorder caused by the loss of genetic material from one of the sex chromosomes. Humans normally have a total of 46 chromosomes (which are tiny, DNA -containing elements) that are present in every cell of the body. DNA encodes genes , which specify all the proteins that make up the body and control its functions. In humans, there are 23 matched pairs of chromosomes in every cell. Each cell contains 22 pairs of chromosomes called autosomes that are the same in males and females. The remaining pair of chromosomes, the X- and Y-chromosomes, are not shaped similarly, and thus are not matched in the same way as the autosomes. The X- and Y-chromosomes are called sex chromosomes. They are responsible for the difference in development between males and females. A Y-chromosome contains genes responsible for

1. THE DOCTOR HAS TOLD ME MY DAUGHTER HAS TURNER SYNDROME, BUT, WHAT IS IT? Turner syndrome consists on the total or partial loss of one chromosome X. This means that instead of two sexual chromosomes these girls have only one chromosome X, at least in a part of their cells. But, generally, having a unique chromosome X doesn’t provoke severe alterations neither physical nor mental. A Turner girl is a normal girl but a bit shorter, with growth problems. This syndrome has nothing to do neither with Down syndrome nor with other syndromes. If we compare a girl or a boy with down syndrome to any man or woman with Turner, we can observe they have a chromosome 21 more and Turner girls have a chromosome X less. That is the only similarity between them, both syndromes have a chromosomal abnormality but no more. Karyotype 46,XX Karyotype 46,XY Karyotype 45,X 2. DOES TURNER SYNDROME EXIST IN BOYS We generally can say that, except in rare occasions, Turner syndrome does only affect women. But we can’ t say without doubts it doesn’t exist in men. The exception is found in boys who combine 45,X cells and 46,XY cells. So, they have characteristic male cells (those which are 46,XY) but they also have typical Turner syndrome cells (45,X). Depending on the embryo time when 45,X cells have appeared, on the kind of organ affected by the mentioned cells and on the chromosome Y being altered or not, the resultant child can be a boy or a girl both with the characteristic features of the syndrome.

34. Turner S Syndrome The genes which are responsible of the development of the male sexual features arelocated in the chromosome Y. However, girls with turner S syndrome have in a http://personal.telefonica.terra.es/web/sindromedeturner/eintroduccion.html

In 1938, Henry Turner described it for the first time in the journal Endocrinology . It was a group of 7 women between 15 and 23 years old. Those women showed a set of physical alteration and made him group them together in a new syndrome called TURNER'S SYNDROME. There were three most typical features described by Henry Turner in those seven women: Infantile sexuality, Pterigium colli and elbow malformation or cubitus valgus These three features among others are still a reference for every doctor or scientist to describe TURNER'S SYNDROME. Sixty-three years later we all know that this syndrome is relatively frequent. It appears in one of every 2500 newborn girls, consequently in approximately one of every 5000 births and in one of every 15 spontaneous abortions. Nowadays, we also know that this syndrome has a well-defined chromosomal base. In 1959 Ford and col., made the first chromosomal analysis to women with Turner's syndrome, they found they all showed a single X chromosome instead of two. It was proved that the TURNER'S SYNDROME was the result of a total or partial absence of the second sexual chromosome in human being. All human beings have 46 chromosomes in our cells, 44 of them are shared by men and women, these are called AUTOSOMES. The other two are called SEXUAL, they are chromosome X and chromosome Y. Except in rare occasions, women have two chromosomes X (we are XX) and men have a chromosome X and a chromosome Y (they are XY). The genes which are responsible of the development of the male sexual features are located in the chromosome Y. However, girls with TURNER'S SYNDROME have in a part of their cells a unique Chromosome X instead of two (they have totally or partially lost the second sexual chromosome) that is why it is said they are 45,X instead of 46,XX.

Beginning at the beginning, such an abnormality is technically called ambiguous genitalia (or atypical genitalia ). Of course, this is classified as a birth defect (or birth variation) of the sex organs that makes it unclear whether an affected newborn is a girl or boy. This condition occurs about once in every 4,500 births. The baby seems to have a mixture of both female and male genitalia. For example, they may have both a vulva and testicles. Associated intersex conditions for male babies include hypospadias , where the urethral opening is located in an unusual position such as the underside of the penis. The causes of ambiguous genitalia include genetic variations, hormonal imbalances and malformations of the fetal tissues that are supposed to evolve into genitals. Tests (including ultrasound, x-rays and blood tests) must be done before the baby's sex can be positively identified. Mild forms of ambiguous genitalia may be characterised by a large (penis-like) clitoris in baby girls or undescended testicles in boys. The latter seems to be the condition in which your question was asked.

Date: Thu Jun 5 14:40:24 2003 Posted By: Frederick Sweet, Ph.D., Professor, Ob-Gyn, Washington University School of Medicine, St. Louis MO Area of science: Genetics ID: 1054761490.Ge Message: The short answer to this question is YES maybe. Some girls with Turner syndrome have excess skin folds around the neck and puffy hands and feet at birth. But this puffiness often disappears during infancy and the extra neck skin becomes less noticeable. So then these possible signs at birth are not conclusive. But genetic analysis is most often conclusive (more about this below). Moreover, aside from Turner syndrome, there are many causes for a child growing slowly. These include: hereditary factors (naturally short parents and grandparents), diseases affecting the kidneys; heart, lungs or intestines; hormone imbalances; severe stress or emotional deprivation and poor nutrition; infections in the womb before birth; bone diseases; and a variety of genetic or chromosomal abnormalities. Chromosomal abnormalities cause Turner syndrome. In 1938
