This study evaluates the effect on spermatogenesis of coadministration of Cytoxan (cyclophosphamide) and nafarelin, a luteinizing hormone-releasing hormone agonist. Nafarelin causes complete aspermatogenesis in dogs by interrupting the hypothalamic-pituitary-gonadal axis, which might protect against the testicular cytotoxicity associated with cyclophosphamide. The four treatment groups, each co...

Advances in cancer treatment allow women to be cured and live longer. However, the necessary chemotherapy and radiotherapy regimens have a negative impact on future fertility. Oncofertility has emerged as a new interdisciplinary field to address the issue of gonadotoxicity associated with cancer treatment and to facilitate fertility preservation, including oocyte and ovarian tissue cryopreserva...

BACKGROUND The aim of this study was to investigate the cellular/biochemical mechanisms by which cisplatin (CIS) causes testicular toxicity. We evaluated the role of inducible nitric oxide synthase (iNOS) expression, mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-kB) activation in the pathogenesis of testicular damage induced by CIS, and investigated the effects of curcu...

Introduction: Ribavirin due to its mutagenic property exerts cytotoxic effects on gonads in a transient fashion that have been studied the testicular tissues of various experimental animals. Ample data is not available regarding toxicity interstitium has led this research.
 Aims & Objectives: Aim study was evaluation ribavirin different doses at time points albino rats.
 Place and...

Systemic lupus erythematosus (SLE) is a chronic autoimmune systemic disease that mainly affects women of reproductive age. Emerging data from recent molecular studies show us that estrogen hormone plays a central role in the development of this disease. By acting via its cognate receptors ERα and ERβ expressed on immune cells, estrogen can modulate immune function in both the innate and adaptiv...

Many chemotherapeutic agents, especially of the alkylating family, alter fertility in premenopausal females. However, it is not practically possible to quantify and characterize the impact of cancer drugs on ovarian reserve in a clinical setting. Thus, our specific aim was to develop a xenograft model to characterize the in vivo impact of chemotherapy agents on human ovary. Ovarian pieces from ...

Background: Cisplatin (CIS), an anticancer alkylating agent, induces DNA adducts and effectively cross links the DNA strands and so affects spermatozoa as a male reproductive tract toxicant. Materials and Methods: The present study investigated the cellular/biochemical mechanisms underlying possible protective effect of selenium nano-particles (Nano-Se) as an established strong antioxidant with...
