Commercialization of animal biotechnologies, including those related to reproduction [also known as assisted reproductive techniques (ARTS)], is an increasing reality in developing countries, following the enormous flow of information around us and the increasing global commercial interests in areas where cattle production has its major assets. The present review discusses the achievements of v...

Medical treatment of men with primary spermatogenic failure remains largely ineffective in contrast to those with secondary testicular failure. Treatment has been attempted with a multitude of agents ranging from hormones to nutritional supplements (antioxidants). While some studies have demonstrated benefit to some treatments, no treatments have consistently demonstrated efficacy nor has it be...

The concern about the maintenance of the human species has existed since the earliest civilizations. Progress in the diagnosis and treatment of infertility has led to the development of assisted reproductive techniques (ART) which, along with the evolution of genetics and molecular biology studies, have contributed in a concrete way to the management of infertile couples. Classic in vitro ferti...

Oligospermia is a major cause of infertility in couples. It is usually managed by assisted reproductive techniques. In these techniques the female partners are treated, while the male partners having this medical problem are left untreated! Though several empirical therapies are available to treat oligospermia, it is difficult to identify a therapy that is most likely to benefit a man having ol...

Approximately 1% of all men in the general population suffer from azoospermia, and azoospermic men constitute approximately 10 to 15% of all infertile men. Thus, this group of patients represents a significant population in the field of male infertility. A thorough medical history, physical examination and hormonal profile are essential in the evaluation of azoospermic males. Imaging studies, a...

This special issue is fully dedicated to the topic of azoospermia and contains the seminal work of renowned scientists and clinicians from seven countries on three continents. In seventeen chapters, a comprehensive review of the epidemiology, genetics, physiopathology, diagnosis, and management of azoospermia addresses our current knowledge on the topic. The clinical results of assisted reprodu...

BACKGROUND/AIM This study determined the effects of cotinine concentrations in follicular fluid (FF) and seminal plasma (SP) on the pregnancy outcome of couples using assisted reproductive techniques (ARTs). MATERIALS AND METHODS This study was conducted as a case-control study. A total of 217 couples were included in the study. Among these couples, there were nonsmokers (66 women and 40 men)...

Recent studies report a high incidence of monozygotic twinning in Beckwith-Wiedemann syndrome. A phenotypical discordance in monozygotic twins is rare. Twinning and Beckwith-Wiedemann syndrome show higher incidence in children born after assisted reproductive techniques. We report on the first observation of esophageal atresia and Beckwith-Wiedemann syndrome in one of the naturally conceived di...

Infertility is a life crisis which leads to serious psychological problems. The present study aims to investigate the effects of hope therapy as a psychological intervention on psychological distresses among infertile women. The present study was an experimental one. The study population included infertile women referring to gynecology clinics. Women who lived in Jahrom and could take part in p...
