Orchidopexy for bilateral undescended testes: A multicentre study on its effects on fertility and comparison of two fixation techniques.

To evaluate fertility potential after orchidopexy for bilateral undescended testis and compare two surgical fixation techniques for effect on fertility. Men older than 22 years who had either tunica albuginea orchidopexy (TAO) or "no-touch" technique (NTO) in childhood for bilateral undescended testis (BUDT) were selected. Participants filled out a questionnaire followed by physical examination, had testicular ultrasound, blood sample and semen analysis.

Development of the testis in pre-pubertal boys with cancer after biopsy for fertility preservation.

Study Question: Is testicular growth affected by a testicular biopsy intended for fertility preservation in pre-pubertal boys with cancer?

Summary Answer: Testicular growth of the biopsied testis is not impeded in comparison to the non-biopsied contralateral testis up until 1 year after surgery.

What Is Known Already: Fertility preservation in pre-pubertal boys by means of testicular biopsy has been conducted for more than 15 years. Although immediate adverse effects of testicular biopsy are rare (1%), no data exist on the effect of biopsy on testicular growth.

Productivity of authors in the field of diabetes: bibliographic analysis of trial publications.

Objective: To determine whether trial publications of glucose lowering drugs are dominated by a small group of highly prolific authors ("supertrialists") and to identify some of their characteristics.

Design: Bibliographic analysis of trial publications.

Data Sources And Review Methods: We searched PubMed for all randomised controlled trials (RCTs) relating to glucose lowering drugs published between 1 January 1993 and 31 December 2013.
