A total of 242 metaphase plates from the peripheral blood of Nubian males living near Aswan, Egypt were studied with respect to the length of the Y chromosome and its location in metaphase spreads. The length of the Y was similar to that found in American Negroes, and the Y chromosome was peripherally located in 79 of the 242 cells.

PIP: Semen analysis was performed on 8 men, every 2 months, for a period of 8 months, after the application of the radiozinc spermatogensis test. Semen was examined for volume, cell count, motility, and abnormal forms. Results showed no evidence of any changes in semen parameters. Student's test was used to compare the data before the test with the data after the test, and no significant differences were seen. The radiozinc spermatogensis test seems safe, from a radiologic point of view, does not have an adverse effect on semen, and unlike testicular biopsy, saves the patient from surgical exposure. The radiozinc spermatogensis test can be applied as an important adjuvant measure in the diagnosis and prognosis of male infertility.^ieng
