Testicular aging starts form age 30 with progressive deterioration of vascularization, the density of capillaries, the diminution of the efficacy of the blood-testis barrier, the aging of Sertoli cells, which results in fall of production of androgen-binding protein. These changes lead to a slow reduction of the number of spermatozoa, although it is their quality that is responsible for male fertility. Analysis of the number, morphology, and mobility of spermatozoa of men aged 25-59 showed that the quality varies depending on age: the maximum values are reached between age 25 and 35, decreasing afterwards. The aging finally results in a degradation of the number and especially in the quality of spermatozoa, which is not satisfactory in individuals of very young age either. Whether male of female, parental aging poses a problem, because fertility diminishes and the risk of anomalies of the conceptus increase with the age of parents. It has been demonstrated that the new, autosomal dominant mutations responsible for fetal deaths or the numerous malformation syndromes, such as achondroplasia, Apert's disease, ossifying fibrodysplasia, and Marfan's syndrome, may be linked to paternal aging. The frequency of each of these syndromes is very low: 15-28 cases per million births for achondroplasia. Also, the frequency of anomalies attributable to paternal aging after the 40s reaches .3-.5% of births. Neurofibromatosis or von Recklinghausen's disease, hemophilia A, the myopathy of Duchenne, schizophrenia, and the performance of 18-year-old males on psychometric tests have been associated with paternal aging. The aging of gonads cannot be prevented, but one could avoid the consequences of the aging of gametes by avoiding having children after 35 or 40 years of age. This has been recommended to women for about 15 years, and perhaps should also be recommended to men.

It was aimed to study the prevalence of major depressive disorder, separation anxiety disorder and suicidal behaviour in the children and adolescents with haemophilia. A total of 83 children and adolescents with haemophilia A or B aged 5-19 years old were randomly selected using systematic random sampling method. They were interviewed using the Farsi (Persian) version of Kiddie Schedule for Affective Disorders and Schizophrenia by face-to-face interview with the subjects and their primary caregivers, according to the DSM-IV diagnostic criteria. Major depressive disorder, separation anxiety disorder and suicidal behaviour were surveyed. The rate of major depressive disorder was 6.0%. Approximately 2.4% of the patients were suffering from at least five symptoms of major depression, and 4.8% were suffering from more than five symptoms of major depressive disorder. One-third of the children and adolescents were suffering from irritability. Approximately 36% of the subjects wished to die at least once during the last 6 months. Also, 6% of the subjects had thought about suicidal attempt. Approximately 4.8% of them met the criteria of separation anxiety disorder. The incidences of major depressive disorder and separation anxiety disorder were comparable to that prevalent in the thalassaemic patients. The proportion of patients with death wish was very high. The proportion of patients with suicidal thought and attempt was much lower than that in the children and adolescents with thalassaemia. Therefore, psychiatric consultation needs to be included in the management of these children.

Electroconvulsive therapy (ECT) is used for medication-resistant and life-threatening mental disorders, and therefore it occupies an important position in psychiatric treatment. ECT reportedly increases intracranial pressure and is suspected of increasing the risk of intracranial hemorrhage, especially in patients with hemorrhagic diseases such as hemophilia. A decrease in or loss of blood coagulation factors, including factor VIII and factor IX, are found in hemophilia A and B, respectively. Psychiatrists may hesitate to perform ECT on patients with bleeding tendencies, such as in hemophilia. Here, we report the successful use of ECT on a neuroleptic-resistant patient with schizophrenia and severe hemophilia A. We performed ECT 16 times supplemented with coagulation factor VIII to prevent intracranial and systematic hemorrhage. We administered factor VIII concentrates to the patient to keep factor VIII activity at 30%-40% during ECT. The patient did not show bleeding or other complications during the ECT sessions. We suggest that pretreatment with factor VIII can help manage the increased risks of intracranial and systematic bleeding during ECT that is present in patients with hemophilia A. The present report supports the idea of performing ECT safely on patients with hemophilia A by administering factor VIII.
