Effect of long-term exposure of 2.4 GHz radiofrequency radiation emitted from Wi-Fi equipment on testes functions.

The aim of this study was to investigate long-term effects of radiofrequency radiation (RFR) emitted from a Wireless Fidelity (Wi-Fi) system on testes. The study was carried out on 16 Wistar Albino adult male rats by dividing them into two groups such as sham (n: 8) and exposure (n: 8). Rats in the exposure group were exposed to 2.

Long-term effects of 900 MHz radiofrequency radiation emitted from mobile phone on testicular tissue and epididymal semen quality.

The purpose of this study is to bridge this gap by investigating effects of long term 900 MHz mobile phone exposure on reproductive organs of male rats. The study was carried out on 14 adult Wistar Albino rats by dividing them randomly into two groups (n: 7) as sham group and exposure group. Rats were exposed to 900 MHz radiofrequency (RF) radiation emitted from a GSM signal generator.

Effects of sildenafil citrate, isoniazid, and streptomycin on testicular tissue and epididymal semen quality in rats.

Objective: To evaluate the effects of isoniazid (INH) and streptomycin (STR) on epididymal semen quality and testicular tissue, and to evaluate the protective effect of sildenafil citrate (SC) on possible testicular toxicity induced by STR and INH in rats.

Methods: Eighty adult male Sprague-Dawley rats were divided randomly into 8 groups including control, SC, INH, STR, STR+INH, SC+INH, SC+STR, and SC+INH+STR. After 45 days of treatment, the reproductive organ weights, epididymal semen quality, testicular histopathological findings, levels of serum nitric oxide, testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were investigated.

Effects of estrous cycle stage and transport temperature of ovaries on in vitro maturation of canine oocytes.

Unlike other domestic animals, in vitro maturation (IVM) of canine oocytes still has limited success. The present study investigated the effects of estrous cycle stage and transport temperature of ovaries on in vitro maturation of canine oocytes. The donor bitches were categorized into three groups based on stage of estrus cycle: follicular (proestrus or estrous), luteal (diestrus) and anestrus.

Evaluation of short estrus synchronization methods in dairy cows.

In the present study, two new short estrus synchronization methods have been developed for lactating dairy cows. The study was completed in three consecutive phases. In experiment (Exp) 1, 32 cows, that were not detected in estrus since calving between the 50th and 84th post-partum days, were treated with PGF2alpha (PGF, d-cloprostenol, 0.

The potential fertility estimation capacity of the hypoosmotic swelling test, the thermal stress test and a modified cervical mucus penetration test in the bovine.

In this study, hypoosmotic swelling (HOS), thermal stress (TS) and modified cervical mucus penetration (mCMP) tests have been used with routine tests for the assessment of semen quality. This is the first study in which the comparison of potential fertility estimation of fore-mention three tests was performed. Bull semen samples were divided into two fertility groups (high: n=3, low: n=3), according to their post-insemination NRR (non-return rate).

The effects of a low dose of cabergoline on induction of estrus and pregnancy rates in anestrous bitches.

This is the first report of successful induction of normal estrus and ovulation in breeder bitches with as a low dose as 0.6 microg/kg/day of cabergoline formulation marketed for use in women. Sixty-one pure breed bitches from various breeds were used in the study at their already determined periods of anestrus.

Relationship between bovine fertility and the number of spermatozoa penetrating the cervical mucus within straws.

In this study, by using a recently developed test technique, the relationship between the total spermatozoa number penetrating determined sites of bovine cervical mucus in straws and potential fertility of bulls, and other spermatological characteristics were investigated. Furthermore, we aimed to determine the effect on the test results, of two different incubation temperatures (37 and 41 degrees C) and two sperm penetration distance ranges (PDRs). Frozen semen samples of six Holstein bulls were used in the study.

Effect of transport and storage temperature of ovaries on in vitro maturation of bitch oocytes.

In this study, the effects of ovary transport and storage temperature on in vitro maturation of bitch oocytes were investigated. Ovaries were collected from 23 mature bitches and one randomly selected ovary of each pair (n=23 pairs) was transported in physiologic saline at 4 degrees C, while the other one at 35-38 degrees C for 2-4h. A total of 316 cumulus oocyte complexes (COCs) were obtained from the 4 degrees C group and 301 COCs from the 35-38 degrees C group.
