Abstract
We report an unusual case of a 55 year old Japanese woman with a seminoma but relatively normal menses. The patient was a phenotypic female with late onset menarche (18 years of age), who was amenorrhoeic for the first year, followed by menses of one to three days' slight flow with dysmenorrhoea, but an otherwise normal menstrual history. A typical seminoma was removed from the left adnexal region and an immature testis was identified separately as an associated right adnexal mass. Repeated karyotypic studies on peripheral blood lymphocyte cultures showed only 46,X,-Y,t(Y;15)(q12;p13). Cytogenetic examination of the patient's younger brother, who had fathered three healthy children, showed an identical karyotype. Mosaicism of 46,X,-Y,t(Y;15)(q12;p13)/45,X cell lines was found in skin samples from the patient's elbow and genital regions, although there were no clinical stigmata of Turner syndrome. An androgen receptor binding assay of cultured genital skin fibroblasts was negative. Molecular analysis using Southern blot hybridisation, PCR, and direct DNA sequencing showed that neither the patient nor her brother had a detectable deletion or other abnormalities of Y chromosome sequences, including the SRY (sex determining region of the Y chromosome) gene sequence. These findings suggest that Turner mosaicism of the 45,X cell line may have contributed to this atypical presentation in an XY female, although we cannot exclude abnormalities of other genes related to sex differentiation.

Abstract
A hypospadiac boy with a hypoplastic penis and an apparent 46,XX karyotype in blood and testis cultures is described. Exploratory laparotomy and bilateral gonadal biopsy revealed the presence of 2 testes in the right and 1 in the left hemiscrotum, each of which only showed hypoplastic testicular tissues histologically. Uncultured testis smears showed Y chromatin in approximately 20% of the cells. Also, the Southern blot and polymerase chain reaction analyses detected a weak but distinct signal of Y chromosome-derived deoxyribonucleic acid sequences in the perineal skin but not in the blood lymphocytes. The results indicated that the boy had a small proportion of Y chromosome-containing cells in the form of mosaicism in limited tissues, such as the testes and perineal skin. This finding may have implications in the genesis of testes in some cases of XX patients, and true hermaphrodites or male pseudohermaphrodites with an apparent 46,XX karyotype. To our knowledge, this appears to be the first case of polyorchidism with an identified chromosome abnormality.

Abstract
A case of a phenotype male with 44 XX karyotype is presented. Clinical, endocrinological and anatomical findings are recorded. Serum level of FSH was elevated, LH level was normal and testosterone level was low. A subnormal response by testicular Leydig cells to hCG was observed. A dexamethasone suppression test and an ACTH test were normal. A B scan ultrasonographic examination did not show female internal genitalia, nor a hyperplasia of adrenal tissue. A review is made of the literature with theories of etiology.

Abstract
The inheritance of several X-linked restriction fragment length polymorphisms ( RFLPs ) is examined in seven 46,XX males and their immediate relatives. The XX males are shown to have inherited a paternal and a maternal RFLP allele in each of the five (of seven) families in which these X-linked markers are informative. In the other two families, a maternal X-chromosomal contribution is demonstrated, but a paternal contribution cannot be determined. We conclude that most, if not all, XX males inherit one paternal and one maternal X chromosome. A segment of single-copy DNA specific to the short arm of the Y chromosome is found to be absent from the genomes of eight XX males. In one of these XX males, an Xp-Yp translocation had previously been inferred from chromosome-banding studies. Our findings argue against mosaicism involving a Y-containing cell line in the XX males examined here, but they do not exclude an X-Y (or Y-autosome) translocation during paternal meiosis. If such a translocation has occurred, the translocation product received by the XX males does not include the Yp-specific sequence tested here.

Abstract
Phenotypic features and functions known to depend on the presence of the Y chromosome or the H-Y antigen are discussed in relation to structural anomalies of the Y chromosome and other abnormalities of sexual and somatic development. Recent knowledge about molecular organization of constitutive heterochromatin in relation to the human Y is presented. An attempt is made at assigning different functions, genes and DNA sequences to different regions of the Y chromosome.

Abstract
A case of gynecomastia and asymmetrical gonadal enlargement in a thirteen and one-half-year-old "male" true hermaphrodite with biopsy-proved bilateral ovotestes is presented. The pathology, genetics, endocrinology, and management of this entity are discussed and compared with instances of hermaphroditism in which there is distinct separation of the ovarian and testicular tissues.

Abstract
Three males with a 46,XX karyotype are described. In two of them, evidence of a Y-containing line was found. In the first case, 1 of 500 lymphocyte metaphases was 48,XXY. In the second, 1 of 400 oral mucosa cells contained a Y body. The proportion of low-grade XX/XXY mosaics found among XX males now stands at about 17%.

Abstract
The status of H-Y antigen was studied in 10 intersexual cases (three pure gonadal dysgenesis with XY genotype, three Klinefelter's syndrome, two true hermaphroditism with XX genotype, two male hermaphroditism) and in 18 normal adult subjects (nine males and nine females). In all these subjects, fluorescent staining and G-banding on chromosomes from cultured leukocytes confirmed their karyotype. Interestingly, H-Y antigen was found to be negative in XY females with dysgenetic gonads (PGD), while in the remaining intersexual states (viz Klinefelter's syndrome, true hermaphroditism and male hermaphroditism), it was found to be positive. These observations confirm that morphological differentiation of testis is controlled by H-Y antigen, and indicate that in the absence of the H-Y antigen, the gonad in pure gonadal dysgenetic patients (46, XY) could not be differentiated into testis, Further, it appears that H-Y antigen in no way influences the secretory function of testis.

Abstract
The accidental discovery, in an inguinal hernia, of a male gonad in a 67-year-old woman is reported. The association of an unambiguous female phenotype with a purely male karyotype and a male gonad suggests the diagnosis of testicular feminisation. The differential diagnosis, particularly of testicular feminisation with true hermaphroditism, is discussed.

Abstract
Two XX males who were second cousins are reported. A genetic mechanism producing maleness is suggested. The putative factor had been transmitted solely through males, which excludes the possibility of a heritable X-Y interchange. Recent reports on fluorescent Y chromatin in Sertoli cells of XX males prompted investigations into the fluorescence patterns of testicular cells. Sertoli cells from three XX males displayed brightly fluorescent spots, but it was concluded that they did not represent Y chromosomes. Evidence for this conclusion was obtained from the study of testicular fluorescence in XX, XXY and XY males. No visually detectalbe cytogenetic evidence for an increase in length or altered banding pattern of one of the X chromosomes was found in three XX males. We conclude that an autosomal gene is the most likely explanation of the male differentiation in the two XX males presented here.

Abstract
To test the hypothesis that H-Y antigen (present on both somatic and germ cells in normal males but not normal females) is essential for testicular differentiation, we studied four XX males and three XX true hermaphrodites. Blood cells from six subjects and cultured gonadal fibroblasts from a seventh expressed H-Y antigen. Since expression of this antigen requires the presence of a gene normally carried by the Y chromosome, this gene, and perhaps additional Y chromosomal material, should have been present in the genome of these subjects. In one patient this presence is accounted for by a Y-to-X translocation, detectable by chromosome banding. In another a normal Y chromosome was present in a minor population of cells. In the remaining five, no karyotypic abnormality was detectable. Immunologic detection of H-Y antigen is a sensitive test for the presence of the Y chromosome or of its male-determining segment.

Abstract
An ambisexual male infant showed a normal female karyotype by the leukocyte culture technique in two different occasions. Cultured fibroblasts from the right gonad had also a 46, XX complement. They were Y-chromatin negative. To our surprise, Y-chromatin was observed in 96% of the nuclei in smears from the uncultured gonad. It is emphasized that the examination of the uncultured gonad by the quinacrine technique is mandatory in the study of "XX males".

Abstract
A 3 year old black male with ambiguous genitalia had a 46, XY karyotype in a bone marrow culture and an intermediate buccal smear result, suggestive of a mosaic of chromatin positive and chromatin negative cells. Upon re-evaluation at age 15 years, he has a 30% positive buccal smear and a 46, XX karyotype in cultures of peripheral blood lymphocytes, skin fibroblasts, bone marrow, and testis. No Y-body fluorescence was detectable in interphase cells from the testicular biopsy or the various cultures. The testicular biopsy appeared similar to that of XXY males, and primary hypogonadism was documented by elevated LH (107 mIU/ml) and FSH (57 mIU/ml) levels in conjunction with low testosterone (142 ng/100 ml). Administration of hCG produced qualitatively normal acute responses of testosterone and estrogens. The cytogenetic data provide support for the theory that at least some XX males once had a Y-containing cell line which was subsequently lost.
