Abstract Objectives were to evaluate characteristics of corpora lutea (CL) and concentrations progesterone (P4) in beef recipient cows stimulated with follicle stimulating hormone (FSH) prior embryo transfer. Forty suckled received the CO-Synch+CIDR protocol randomly assigned one two treatments: 1) exogenous FSH (FSH; 1.0 mL im 2x/d on d -4 -3, 0.5 -2 -1) or 2) no treatment (CON). Estrous behav...

Lactating Holstein cows (n = 141) were synchronized to receive their first timed artificial insemination (TAI). Blood and milk samples were collected 25 and 32 d after TAI, and pregnancy status was determined 32 d after TAI using transrectal ultrasonography. Cows diagnosed pregnant with singletons (n = 48) continued the experiment in which blood and milk samples were collected and pregnancy sta...

This study aimed to obtain the ultrasound image of preovulatory follicle growth in gayo mares predict ovulation time. used three Gayo and one stallion for teaser aged 5-10 years weighed 200-250 kg. Preovulatory was observed using transrectal ultrasonography which performed when dominant size ≥ 3.5 cm. Observations were made 3 consecutive estrous periods on at relatively same The absence previou...

Use of GnRH in AI protocols results in ovulation of a wide range of follicle sizes. Our objective was to determine the effect of ovulatory follicle size at GnRH-induced ovulation or standing estrus on pregnancy rates and embryonic/fetal mortality. Lactating beef cows (n = 273) received the CO-Synch protocol (100 μg GnRH, i.m. on d -9; 25 mg PG, i.m. on d -2; and 100 μg GnRH, i.m. on d 0 with ti...

BACKGROUND Congenital absence of the vas deferens is an important cause of obstructive azoospermia, and the lack of an imaging diagnostic test is a critical problem. The aim of this study is to discuss the use of ultrasonography in congenital absence of vas deferens, including dysplasia of the epididymis and the seminal vesical. MATERIAL AND METHODS Five fresh spermatic cord specimens were dete...

The insulin-like growth factors (IGFs) have mitogenic effects on normal and tumoral prostate epithelial cells and have been suggested to be involved in prostate cancer. Moreover, chronic GH and IGF-I excess causes prostate overgrowth in patients with acromegaly. This study was designed to investigate whether the suppression of GH and IGF-I levels by surgery or pharmacotherapy could induce the r...

BACKGROUND Artificial insemination (AI) using frozen-thawed semen is well established and routinely used for breeding in various mammalian species. However, there is no report of the birth of elephant calves following AI with frozen-thawed semen. The objective of the present study was to investigate the fertilizing ability of chilled and frozen-thawed semen in the Asian elephant following artif...

Chronic prostatitis is hard to be identified in BPH patients clinical works. This study aimed diagnose chronic by noninvasive methods. who received transurethral resection of prostate from January 2014 July 2015 were enrolled current study. Patients examinations PSA, sex hormones, inflammatory cytokines, metabolic panel and transrectal ultrasonography. According histological results, divided in...
