15. Investigation of allele frequencies of polymorphic variants in genes that are related to polycystic ovary syndrome
SUMMARY OBJECTIVE: Polycystic ovary syndrome is a hormonal disorder that normally affects women of reproductive age in the range of 18–44 years. This study aimed to investigate the allelic frequencies of two polymorphisms, IRS rs18012781 and INSR rs1799817, which are suspected to be involved in polycystic ovary syndrome. METHODS: The samples were obtaine

19. The combined effect of lifestyle intervention and antioxidant therapy on sperm DNA fragmentation and seminal oxidative stress in IVF patients: a pilot study
ABSTRACT Purpose: Sperm DNA fragmentation (SDF) and seminal oxidative stress are emerging measurable factors in male factor infertility, which interventions could potentially reduce. We evaluated (i) the impact of lifestyle changes combined with oral antioxidant intake on sperm DNA fragmentation index (DFI) and static oxidation-reduction potential (sORP), a

20. Superiority index based on target traits reveals the evolution of Brazilian soybean cultivars over last half-century
ABSTRACT The objective of this work was to assess the breeding influences in different agronomic and physiological traits in Brazilian soybean cultivars, released between 1965 and 2011, to identify traits associated with modern cultivars. A total of 29 cultivars were evaluated in two locations in the 2016/17 crop season. Genotype selection based on agronomic

22. Semen quality from patients affected by seminomatous and non-seminomatous testicular tumor
ABSTRACT Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), compr
