ovary and ovarian bursa of twelve female reproductive organ, six samples from each immature and mature buffaloes were collected from slaughterhouse. all samples were transferred to anatomy department of veterinary college, and they studied morphologically and morphometrically, length, wide, and thickness of ovaries, deep and wide of opening of ovarian bursa were measured. additionally, dimensio...

for the present study, and follow-up of histochemical changes in estradiol valerate-induced polycysticovary syndrome (pcos), 48 virgin 90-day-old female rats were used. the rats were divided into thetreatment and control groups. for each rat of the treatment group, 4 mg estradiol valerate was injectedthrough intramuscular route for the induction of pcos. the control group was taken the same amo...

High-producing dairy cows are subfertile; however, the mechanisms responsible for the decreased fertility are unknown. The aim of the present study was to test the hypothesis that culled dairy cows (4-8 years old) characterised by 'Lo' ovaries (i.e. those with <10 mid-antral follicles) are affected by premature ovarian senescence. Cows in which both ovaries were 'Lo' ovaries represented 5% of t...

background: auto antibodies to zona-pellucida (aza) seem to be important autoantibodies implicated in reproduction, with substantial role in both endocrine and reproductive functions of the human ovary. there are some debates on the relation of aza with infertility, repeated in vitro fertilization (ivf) attempts, and outcome of it. objective: in this study, we assessed the presence of aza in th...

The ovary of neonatal nonhuman primates contains the highest number of immature oocytes, but its cryopreservation has not yet been sufficiently investigated in all life stages. In the current study, we investigated cryodamage after vitrification/warming of neonatal ovaries from a nonhuman primate, the common marmoset (Callithrix jacchus). A Cryotop was used for cryopreservation of whole ovaries...
