Chemotherapy of non-Hodgkin lymphoma (NHL) with cyclophosphamide,
doxorubicin, vincristine, and prednisone (CHOP) is associated with significant
gonadal damage. Our goal was to determine the impact of CHOP chemotherapy on
the male reproductive system, fertility, and progeny outcome in the rat model.
Adult male Sprague-Dawley rats received saline or CHOP, 4 cycles of 3 weeks
each, at doses analogous to 1/3x, 2/3x, or 1x the human
dose; males were mated to evaluate effects on progeny outcome. Reproductive
organ weights were significantly decreased in the 1x CHOPexposed
group. The spermatozoal contents of the testes and epididymides were decreased
in 1x CHOPtreated males; the 1/3x and 2/3x doses also
affected testicular sperm contents. Seminiferous tubule diameters were
decreased by 20% in 1x CHOPtreated males. Damage ranged from the
presence of small vacuoles in the epithelium to tubules deprived of
spermatocytes and spermatids and was accompanied by an increased incidence of
germ cell apoptosis. The acridine orange assay revealed a significant increase
in sperm with abnormal DNA integrity profiles in the 1x CHOP group.
Despite effects on germ cell number and quality, CHOP-exposed rats remained
fertile. However, a 50% decrease in live fetuses was observed in litters sired
by 1x CHOPtreated males due to a significant increase in both
pre-implantation and postimplantation losses; postimplantation loss was also
elevated among litters sired by 2/3x CHOPtreated males. Thus,
CHOP treatment affected both the quantity and quality of male germ cells;
conceptal loss is a sensitive measure of the integrity of the male genome.
Key words: Anticancer drugs, spermatogenesis, male germ cell apoptosis, adverse effects, developmental toxicity
