Abstract:The cyclophosphamide is used in cancer treatment. The aim of this study was evaluating the effect of different doses of this drug on male mice reproductive parameters. The cyclophosphamide was administered in the doses 100, 150, 200 e 250 mg.kg -1 , intraperitoneal route, for six weeks. As a result, it was observed a decrease in body mass and a decrease in testicles and kidney's weight, in all animals treated with cyclophosphamide. Only the groups that received the doses 100, 150 mg.kg -1 of cyclophosphamide w… Show more

There was also loss of interstitial space between In this study, administration of cyclophosphamide was associated with significant weight loss, which is consistent with reports of previous studies in rodents (Kanno, Sensiate, Aparecida de Paula, & Salles, 2009;Kumar, Singh, & Reddy, 2013;Latha & Panikkar, 1999;Myers et al, 2017). In the group where Maca alone was administered at 500 mg/kg (Figures 3e and 4e), there was an increase in sperm concentration within the ducts; duct epithelium and cells were normal and well preserved.…”

Effects of Lepidium meyenii (Maca) on cyclophosphamide (CYP)-induced gonadal toxicity in male mice were investigated. Mice were assigned to six treatment groups: Vehicle control, CYP control, CYP plus oral Maca (500 or 1,000 mg/kg), and oral Maca (500 or 1,000 mg/kg). CYP was administered via the intraperitoneal route (days 1-2), while vehicle or Maca were administered daily for 28 days. On day 28, half of the animals in each group were either sacrificed or paired with age-matched females for fertility assessment. Plasma testosterone assay, sperm analysis and assessment of tissue antioxidant/morphological status were also carried out. CYP administration was associated with oxidative stress, subfertility and morphometric/morphological indices of gonadal injury, while administration of Maca mitigated CYP-induced gonadal toxicity and subfertility. This study shows that Maca is beneficial in the mitigation of CYP-induced male gonadal insufficiency and/or testicular morphological changes; however, further studies will be needed to ascertain its usability for this purpose in humans.

“…Several studies on male rats have confirmed that the administration of CP resulted in oligospermia, azoospermia, and histological alterations in the testes [1,13,14]. A wide range of adverse effects including reproductive toxicity have been found following CP treatment in humans and experimental animals.…”

BackgroundCyclophosphamide (CP) is used extensively as a chemotherapeutic and an immunosuppressive agent during organ transplantation. However, its clinical utility is limited by adverse actions on the human reproductive system. Melatonin is detected in the human and animal reproductive system, hence assumed to play a useful role in the reproductive cells.
Aim of workTo examine the effect of melatonin on the histological and immunohistochemical changes that appear in the cells of the testes of albino rats treated with CP.
Materials and methodsForty-two adult male albino rats were classified into group I (control), subgroups IIa and IIIa (CP by an intraperitoneal injection for 2 and 5 weeks, respectively), subgroups IIb and IIIb (CP and melatonin by an intraperitoneal injection for 2 and 5 weeks, respectively), and subgroups IIc and IIIc (CP for 2 and 5 weeks and left for 2 and 5 weeks for recovery, respectively). The rats were weighed, sacrificed, and the right testes were weighed and processed for paraffin sections. A histological study was carried out using H&E and Masson's trichrome. Immunohistochemical study using the BCL2 antiapoptotic onchoprotein and a morphometric study were carried out. Results A significant decrease was found in the mean body weight in subgroups IIa, IIIa, and IIIc and in the mean testicular weight in group III. There were distortions in some seminiferous tubules, degeneration of spermatogenic cells, perivascular and intertubular fibrosis, and negative immunoexpression of BCL2. These changes were more marked in group III than in group II. The use of melatonin in subgroups (IIb, IIIb) conferred partial protection against all of the above-mentioned changes.
ConclusionProlonged administration of CP to rats can induce testicular lesions. Withdrawal of the drug does not ameliorate this effect. The concomitant administration of melatonin with CP led to a partial improvement in testicular lesions induced by CP.
“…Este é um substrato da enzima aldeído desidrogenase e, em células que contém esta enzima, a maior parte do 4-HOCy é oxidado a carboxifosfamida (um agente citotóxico) e excretado na urina. Consequentemente, células contendo elevada concentração de aldeído desidrogenase são resistentes aos metabólitos da ciclofosfamida (DeVITA; HELLMAN;ROSENBERG, 2000;JENSEN et al, 2008;KANNO et al, 2009) .…”
