The occurrence of bacteria in sperm samples intended for in vitro fertilisation can compromise the outcome of assisted reproductive techniques. Effective semen processing procedures should therefore be implemented to remove bacteria from semen. Unfortunately, technique failure does occur whereby bacteria can be found in processed sperm preparations. To improve the effectiveness of semen process...
Horizontal attenuation total reflection Fourier transformation infrared spectroscopy (HATR-FT-IR) studies on cuscutae semen and its confusable varieties Japanese dodder and sinapis semen combined with discrete wavelet transformation (DWT) and radial basis function (RBF) neural networks have been conducted in order to classify them. DWT is used to decompose the FT-IRs of cuscutae semen, Japanese...
INTRODUCTION Prolonged survival of patients under HAART has resulted in new demands for assisted reproductive technologies. HIV serodiscordant couples wish to make use of assisted reproduction techniques in order to avoid viral transmission to the partner or to the newborn. It is therefore essential to test the effectiveness of techniques aimed at reducing HIV and HCV loads in infected semen us...
Campylobacter is one of the most commonly reported bacterial causes of human foodborne infections in the United States. Recent evidence has demonstrated that Campylobacter is present in poultry semen and may contribute to the vertical transmission between the breeder hen and offspring. As Campylobacter is considered sensitive to oxygen and cold temperature, the objective of this study was to de...
Bangladesh possesses a tropical goat breed popularly known as Black Bengal goat. They are dwarf in size and noted to be famous for their adaptability, fertility, prolificacy, delicacy of meat and superior skin quality (Husain et al. 1996). It is well adapted to hot and humid climate and usually produces twins and triplets. However, it has been observed that there exists sizeable genetic variati...
Objective: To assess the seminal characteristics of multiple ejaculates collected sequentially via masturbation or at intercourse using a semen collection device (Male Factor PakTM; MFPTM). Design: Three ejaculates were collected by patients over a 3 day period (1 semen specimen/day) via masturbation or at intercourse by using the MFPTM. Semen specimens were assessed for volume (ml), sperm coun...
Artificial insemination via cooled or frozen-shipped semen allows more mares to be bred to a single stallion, but not all stallions produce semen capable of withstanding the cooling and freezing procedures. Aurich et al. (1996) estimated that cooled or frozen-shipped semen achieves < 75% of the pregnancy rates achieved with fresh semen. Some factors affecting the fertility rates of thawed semen...
AIM The objective of this research is to report parameters for breeding soundness evaluation, semen extension, and cryopreservation in Rusa timorensis. MATERIALS AND METHODS Seven healthy stags were chosen for semen collection using an electroejaculator. The collections were performed twice in a breeding season between February and June 2016. Samples were collected between 2 and 3 weeks inter...
The present study was conducted to determine the correlation of hypo-osmotic swelling test with conventional semen evaluation parameters of fresh semen collected from two Nili-Ravi buffalo and two Sahiwal cow bulls. A total of 10 pooled samples (each comprising two consecutive ejaculates) from each bull were collected. Each semen sample was divided into two parts. One part was used for the eval...
A comparative study of the sialic acid content of semen, serum and spermatozoa from several mammalian species was made. The sialic acid content of semen showed a very wide range of concentration in the four species examined, while the sialic acid concentrations in serum were much more uniform. The semen from man and bull contained higher concentrations of sialic acid than the serum of these res...
