The aim of the present study was to investigate the effect of follicle stimulating hormone (FSH) on survival, activation and growth of ovine primordial follicles using histological studies. Pieces of ovine ovarian cortex were obtained and cultured for 6 days in Minimum Essential Medium supplemented with or without FSH (50 ng/mL). These fragments were then process to be used for histology compar...

Background Melatonin (N-acetyl-5- methoxytryptamine) is mainly synthesized and secreted in the pineal gland, ovary, testes, bone marrow, retina and lens in mammalian species. It is involved in the detoxification of ROS and protects embryos from oxidative damage. Melatonin acts as a potential free radical scavenger, including peroxyl radical and hydroxyl radical. In addition, it can stimulate th...

This little booklet, though planned to help the American family with a retarded child living at home, would be of use and encouragement to any mother confronted with the same problem. It is simple and practical and the advice given is sound common-sense.

AIMS To investigate the effects of elevated nitric oxide (NO) levels in peritoneal fluids (PF) on oocyte fertilization and pre-implantation embryo development, and the relation of those effects to endometriosis-associated infertility. METHODS PF from women undergoing laparoscopy for infertility of minor endometriosis, tubal blockage and operation for tubal ligation was aspired at the pouch of...

a procedure was developed for rapid in vitro germination of linum album seeds by scarification and exposing to gibberellic acid (ga3) and kinetin (kn).  concentrations of podophyllotoxin (ptox) and related aryltetralin lignans α-peltatin, β-peltatin, 5’-demethoxy-6-methoxypodophyllotoxin and 6-methoxypodophyllotoxin (mptox) in l. album fresh plant organs were determined by hplc. a degree of var...

background: linoleic acid (la) is a polyunsaturated fatty acid present in high concentrations in follicular fluid, when added to maturation culture media, it affects oocyte competence.objective: in the present study, we investigated effect of linoleic acid supplementation on in vitro maturation, embryo development and apoptotic related gene expression in ovinematerials and methods: the experime...

Background: Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial glands and stroma surrounded by dense fibrous tissue. Whereas, normal eutopic endometrium shows scarless tissue repair during menstrual cycles, which suggests that the endometriotic tissues have distinct mechanisms of fibrogenesis. During the development of en...
