Abstract

The functions of the ovaries are controlled by many exogenous and endogenous factors, including changes in the biochemical and endocrine glands that occur in the follicular fluid during the breeding season in the bitches. The aim of this study was to determine and compare the concentrations some hormonal in the peripheral circulation and follicular fluid of bitches during the breeding season. For this purpose, ovaries collected from adult bitches immediately after ovariectomy, and blood samples were also collected from these bitches before and after season. The follicular fluid and blood serum samples were analyzed for hormonal concentrations using commercial kits. The results showed that the concentrations of estrogen, progesterone and testosterone in blood serum at season (54.31±0.49, 20.75 ±0.12, 0.75±0.05) respectively. While the concentrations of estrogen, progesterone and testosterone in blood serum at out season (10.88±0.39, 0. 61±0.036, 0.063±0.042) respectively. The concentrations of estrogen, progesterone and testosterone in follicular fluid at season (69.9±0.44, 28.46±0.82, 0.331±0.65) respectively. While the concentrations of estrogen, progesterone and testosterone in follicular fluid out season (there are no found ovarian follicles). The present study a significantly higher (P< 0.05) in blood serum and follicular fluid at season than that out season blood serum.

Abstract

This project was designed to study some metabolites and ionic composition of ovarian follicular fluid and to relate possible changes in composition to follicular size.Ovaries were collected (120ovary) from 60 adult females camels (5-10 yr. old) slaughtered at slaughterhouse of province of Karbala in breeding season (winter). The ovaries were transported to the laboratory within 2 hours post slaughter. The follicular fluid was aspirated from small follicles (4-9mm) and large follicle (10-20mm).The follicular fluid was stored at -4 Cº prior to assay. Follicular fluid samples were analyzed for metabolites composition (glucose, total protein and cholesterol), and ionic composition (sodium, calcium and potassium). The results showed that the mean glucose and cholesterol concentration were increased significantly (P<0.05) with increased of follicular size, while the mean total protein concentration decreased significantly with inlargement of follicular size. Likewise, the mean sodium and calcium ions concentration increased significantly with changes of follicular size, while the mean potassium ion concentration decreased significantly with increased of follicular size.

Abstract

The aim of this study was to evaluate the association between the follicular fluid (FF) malondialdehyde (MDA) levels as a free radical marker and reduced glutathione (GSH) as antioxidant and pregnancy after intracytoplasmic sperm injection (ICSI).A total seventy-five infertile women aged between 22-45 years(31.43 ± 5.38 years), referred to the fertility clinic in Al-Sadder teaching hospital, , and undergone intracytoplasmic sperm injection throughout period from March 2013 to January 2014,were included in this study. follicular fluid (FF) malondialdehyde was measured by spectrophotometer based on the calorimetric reaction with thiobarbituric acid (TBA) and follicular fluid glutathione was measured by spectrophotometer depends on the action of sulfhydryl groups.Out of the 75 included patients, 15 (20%) achieved pregnancy after ICSI. Pregnant women were associated with significantly higher MDA level (P < 0.05) and lower GSH (P < 0.05) .There was a significant positive correlation between MDA and the number of pronucleus ( r= 0.326 ). The best cutoff value of FF.MDA and FF GSH associated with pregnancy were 3.49 µM and 26.90 µM respectively. Higher FF MDA and lower FF GSH levels are associated with pregnancy after ICSI. Oxidative stress parameters may be markers of metabolic activity within the follicle.

Abstract

Estradiol (E2) is a steroid hormone produced mainly by the ovary and placenta and in small amounts by adrenals and testes. Estradiol is in equilibrium with estrone, which can be converted to estriol by the liver and placenta. Like for LH-FSH-progesterone, measurement of estradiol concentration is an essential biochemical tool for the investigation of fertility. So that this study was done to assess the follicular fluid E2 in early follicular phase as a predictor of pregnancy rate among females undergoing in vitro fertilization (IVF) in Iraqi patient. The study population consisted of women undergoing in vitro fertilization and aged between 18 - 45 years. The medical records of 56 infertile patients undergoing IVF in the program at center of Baghdad center in the period between February 2015 and July 2015.This study resulted in a pregnant women were 11 (20%) while the non-pregnant women were 45 (80%). The mean levels of E2 fluctuated among different age groups showing significantly with age >35 as compared with another group. The mean levels of E2 in follicular fluid fluctuated among different BMI groups showing that mid 30 year women had more chance to have pregnancy through IVF, and there's no significant between pregnant and non-pregnant. When related to BMI, IVF result showed that the chance of IVF success increased with decreased BMI. This implies that slim women had more chance to have pregnancy through IVF. Furthermore, level of E2 in follicular fluid couldn't be used in IVF as a predictor success of pregnancy.

Abstract

The estimation of oocyte quality in human in vitro fertilization (IVF) is an important point for the embryologists. Oocyte selection and the identification of the best oocytes may help to limit an overproduction of embryos and to improve the results of oocyte cryopreservation programs.The follicular fluid (FF) can be provided easily during oocyte pick-up and known to represents an optimal source for non-invasive biochemical predictors of oocyte quality. However, till now no substance was found to be used as reliable markers of oocyte competence to fertilization, embryo development and pregnancy.Metabolism and ATP levels within the oocyte and adjacent cumulus cells are associated with quality of oocyte and optimal development of a healthy embryo. Lipid metabolism provides a potent source of energy and its importance during oocyte maturation is being increasingly recognised.

Abstract

Background:In vitro maturation (IVM) is a culture technology that enables the immature oocytes to reach metaphase II (MII). Vitrification of immature oocytes followed by in vitro maturation can offer advantages, such as to avoid the use of large doses gonadotropins and also be an alternative approach to the use of endocrine stimulation to obtain pre-ovulatory oocytes in all cycles.Objective:The objective of the study is to determine the effect of vitrification technique and several biochemical materials on outcomes of in vitro maturation.Materials and Methods:Normal and viable immature oocytes divided into two major groups including: control group and vitrification technique group. Post-thawing, each major group subdivided into four in vitro maturation (IVM) groups using SMART medium with special additives involving: (G1) group: contained gonadotropins (Gn) only, (G2) group: supplemented with Gn and sucrose (4%), (G3) group: consisted of Gn, sucrose (4%) and follicular fluid (FF) (5%), and (G4) group: contained Gn, sucrose (4%) and FF (10%).Then, assessed the results of in vitro maturation.Results:The results of in vitro maturation for control group shows non significant differences (P>0.05) among all groups. While, a significant increase (P<0.05) in percentage of IVM was achieved when compared G3 and G4 groups with G1 and G2 groups in vitrification technique. Therefore, comparison the results of IVM between control group vitrification technique group appeared a significant difference (P<0.05) in G1 groups and also between G2 groups. However, non significant difference (P>0.05) was appeared between G3 groups and also between G4 groups when comparing between control group and vitrification technique group.Conclusions:Vitrification of immature oocytes were appeared as a promise technique for preservation of oocytes. As well as, the addition of follicular fluid (FF) to maturation medium produced the best results for in vitro maturation (IVM).

Abstract

The current study was conducted to investigate the impacts of active and passive immunization against synthetic inhibin-α subunit and steroid-free bovine follicular fluid, respectively, on reproductive hormones profile out of breeding season in Iraqi Awassi ewes. Follicular fluid was aspired from mature bovine follicles, treated with activated charcoal, used for immunization of male rabbits, and obtaining of SFBFF antiserum. Forty non-pregnant Awassi ewes were allocated into 4 groups (n = 10 each). At day 38 of experiment, ewes were treated with intra-vaginal sponge impregated with medroxyprogesterone acetate 60 mg for 12 days. Ewes were treated at 0, 28 and 50 days with 4, 2 and 2 ml of normal saline (control; C-ve), 400, 200 and 200 µg of ovalbumine (C+ve), 400, 200 and 200 µg of inhibin (SI group), and 4 ml of normal saline at 0 day, and 4ml and 2ml of SFBFF antiserum, at 28 and 50 days, respectively (AI group). Blood samples were collected at 24 and 48 hours before and after sponge withdrawal for assessment of FSH, LH, inhibin-B, Activin-A, E2 and P4. Before sponge withdrawal, FSH level increased in SI ewes, whereas only after sponge withdrawal, FSH, LH, activin-A and E2 levels increased in SI and AI ewes. Opposite results were shown of inhibin-B level. In conclusion, active or passive immunization against inhibin in Awassi ewes could augment reproductive functions out of breeding season in Iraqi Awassi ewes.
