Background: Infertility problem affect more than 15% of young couples in different societies. One of the known causes of ovulation disorder is chemotherapy in patients with cancer. This side effect may last from ten years up to the end of the life. Antioxidents and reactive oxygen species (ROS) are in balance in the body. Oxidative stress is mainly insert their effect through decreasing of cell...

Background Today, cryopreservation of ovarian tissue has been the effective procedure to restore fertility in can cer patients. It is well known that oxidative stress (OS) is a widespread phenomenon that occurs in ovary cryopreservation. Numerous studies show that follicular atresia in mammalian species due to the accumulation of toxic metabolites often results from oxidative stress. Therefore,...

In lizards, the eggs are produced within small regions of the ovary known as germinal beds (GBs); previous literature suggests that the number of GBs per ovary may be linked to life-history traits such as clutch size and breeding frequency. In the oviparous montane Australian skink Bassiana duperreyi, females produce a single clutch of 3 to 11 eggs each year. Our histological examination of ova...

The aim of this work was to study the influence of hypokinetic conditions on the ovary and corpus luteum of pregnant rats. The rats were kept in hypokinetic conditions for 5 days in the period between the 13th and 18th days of pregnancy. A three-dimensional reconstruction of the ovary and corpora lutea and also a stereological evaluation of the luteal cells and their nuclei were performed using...

The purpose of this paper is to provide a stepwise approach to treating the infertility/subfertility associated with polycystic ovary syndrome. Defining polycystic ovary syndrome in a patient requires first investigating other possible causes for polycystic ovary morphology, acne, hirsutism, obesity, and the metabolic derangements that often accompany polycystic ovary syndrome. Beginning with l...

The aim of this study was to evaluate the effect of ovarian tissue fragmentation before preservation at 4C in MEM on the morphology, apoptosis, and growth of ovine preantral follicles. After collection, the ovaries were divided into two halves, being one divided into two fragments (1/4 of the ovary). One fragment was subdivided into two fragments (1/8), being one fixed for histology (fresh cont...

Polydesmida is the largest order in the class Diplopoda in terms of the number of species, genera and families, but there are few studies of the ovarian morphology of species in this order. This study aimed to perform a comparative study of the ovarian morphology of three species from this order to increase the understanding of the morphological evolution of this system in Polydesmida. Adults f...

Platyscytus decempunctatus Carvalho is a small mirid living throughout its life cicle plant Solanum cernuum Vell. (Solanaceae). The internal morphology of P. decempunctatus was studied and found that the female has a telotrophic ovary with three ovarioles in the right ovary and five in the left one. In the male reproductive trait there is a well developed tubular accessory gland. The phytophago...
