However, the diagnosis is often unknown at birth, and therefore late. In Ivory Coast, there are few studies on cryptorchidism and micropenis. We conducted this study to identify the epidemiological, clinical, etiological and therapeutic characteristics of the micropenis associated or not with cryptorchidism at Yopougon University Hospital. Methods: We conducted a retrospective descriptive study in the Department of Endocrinology-Diabetology of the Yopougon University Hospital carried out over 13 years from January 2005 to December 2018. All patients were included regardless of the presence of a micropenis associated or not with cryptorchidism in the clinical or paraclinical examination. Results: A total of 14 micropenis were reported associated in 6 cases with cryptorchidism. It was unilateral cryptorchidism in 4 patients or 66.66% of cases. The average age of affected patients was 21.32 years with extremes ranging from 10 months to 48 years. The reason for consultation was micropenis in 12 out of 14 cases or 85.75%. The associated signs apart from cryptorchidism were obesity in 42.86% of cases, gynecomastia in 35.71% of cases. The aetiology was dominated by idiopathic causes. Treatment with testosterone enanthate was more effective in pre-pubertal children than in adults. Conclusion: The diagnosis of micropenis associated or not with cryptorchidism is late because of the frustrations, taboos and psycho-social states that it causes. However, drug treatment is effective when treatment is started early.展开更多

A total of 83 crytorchid testes (57 unilateral and 13 bilateral) were recognised in 70 animals post-slaughter at three abattoirs in the south west of England between June 2000-January 2004. Abdominal cryptorchids (60) were common than inguinal (23);69% percent of cases were unilateral. External examination for cryptorchidism was carried out on 5134 young male lambs carried out in 2001 at Foot and Mouth Disease disposal sites, and on farms, during the UK outbreak of the disease. A total of 29 cases of cryptorchism [0.56%] were detected;86% of cases were unilateral. In both situations the right testis was more commonly affected than the left.展开更多

The hyper-color force is a generalization of the SU(2)-based weak interaction and the SU(1)-based right-chiral self-interaction, in which the W-and the Z-bosons are Yukawa residual-field-carriers of the hyper-color force, in the same sense as the pions are the residual-field-carriers of the color SU(3) interaction. Using the method of numerical minimization of the SU(4)-action based on this model, the masses and the inner structure of leptons, quarks and weak bosons are calculated: the mass results are very close to the experimental values. We calculate also precisely the value of the Cabibbo angle, so the mixing matrices of the Standard model, CKM matrix for quarks and PMNS matrix for neutrinos can also be calculated. In total, we reduce the 29 parameters of the Standard Model to a total of 7 parameters.展开更多
