Background: Vitrification is a process that can be used to preserve gonads in the
healthy and natural status. Oxidative stress is one of the disadvantages of
vitrification. Pentoxifylline (PTX) is an antioxidant that can reduce reactive
oxidative stress effects.
Objective: We aimed to investigate the effects of PTX on histological and ultra-structural
features of vitrified and non-vitrified mouse ovarian tissue.
Materials and Methods: Twenty-five adult female Balb-C mice were randomly and
equally divided into control group: the ovaries did not receive any treatment;
experimental 1 and 2: the vitrified ovaries were incubated in phosphate buffer
solution and bovine serum albumin without and with PTX, respectively, for 30 min;
sham 1 and 2: the non-vitrified ovaries were incubated in phosphate buffer solution
and bovine serum albumin and were incubated without and with PTX, respectively
for 30 min. The right and left ovaries in all of the groups were evaluated using light
and transmission electron microscopy, respectively.
Results: The histological and ultra-structural features of vitrified ovaries were
seriously damaged. There was non-uniformed germinal epithelium and tunica
albuginea, degenerated granulosa cells and stromal cells, puffy basement membrane
and irregular thickness of zona pellucida, as well as a pyknotic nucleus and bubbly
and segmented ooplasmic in the follicles. Also, ovarian tissues were damaged by the
PTX in the non-vitrified ovaries.
Conclusion: Vitrification can damage the histological and ultra-structural features
of the ovary in mouse models. PTX as an antioxidant, with concentration of 1.8 mM
could not prevent and restore these damages and had no adequate effects on the
vitrified ovarian tissues.
