Cryopreservation of immature testicular tissue before chemo/radiotherapy is the only option to preserve fertility of cancer-affected prepubertal boys. To avoid reintroduction of malignant cells, development of a transplantable scaffold by decellularization of pig immature testicular tissue (ITT) able to support decontaminated testicular cells could be an option for fertility restoration in thes...
Background: Medicinal herbs are important in the treatment of diabetes. Studies have shown that diabetes causes reproductive changes in the male population. This study aimed to examine the effect of the hydroalcoholic extract of Nectaroscordum tripedale on testicular tissue changes in diabetic male rat. Materials and Methods: In this experimental study, 40 male rats were randomly divided into f...
Background: Gibberellic acids are naturally occurring plant hormones that are used in agriculture as plant regulators and enter animals and human cells through diet. This study was undertaken to investigate effects of gibberellic acid on testicular tissue of adult rats. Materials and Methods: Twenty seven adult male Wistar rats after a one week acclimatization period were randomly divided into ...
STUDY QUESTION Can human spermatogonia be detected in long-term primary testicular cell cultures using validated, germ cell-specific markers of spermatogonia? SUMMARY ANSWER Germ cell-specific markers of spermatogonia/spermatogonial stem cells (SSCs) are detected in early (1-2 weeks) but not late (> 6 weeks) primary testicular cell cultures; somatic cell markers are detected in late primary t...
Testicular tissue cryopreservation is the only potential option for fertility preservation in pre-pubertal boys exposed to gonadotoxic treatment. Completion of spermatogenesis after in vitro maturation is one of the future uses of harvested testicular tissue. The purpose of the current study was to evaluate the effects of vitamin A on in vitro maturation of fresh and frozen-thawed mouse pre-pub...
The effect of coenzyme Q10 on oxidative stress parameters and testicular tissue damage in rats following monosodium glutamate induced excitatory intoxication
OBJECTIVE To determine whether decreased testicular levels of enzymes necessary for retinoic acid biosynthesis were associated with male infertility, as retinoic acid is known to be necessary for spermatogenesis. DESIGN Observational analysis of testicular tissue samples, sperm indices, and serum hormone concentrations. SETTING Two infertility centers in Chile. PATIENT(S) 32 infertile men...
