PURPOSE To date, standard semen parameters have been the only parameters investigated in sperm samples of infertile men in Algeria. We investigated, for the first time, semen parameters according to sperm DNA fragmentation (SDF) in these subjects. MATERIALS AND METHODS SDF was determined by a validated sperm chromatin dispersion test in 26 infertile men. Patients were split into two groups ac...

Purpose To determine whether reactive oxygen species (ROS) in semen samples could be measured with the Monolight™ 3010 Luminometer. Methods Using the Monolight™ 3010 Luminometer, the ROS was measured in the unprocessed semen samples of infertile male patients, as well as the luminescence of 190 semen samples. The samples were classified as "luminescence-detectable" (n = 89) and "luminescence-...

OBJECTIVE To study the relationship between semen quality and pregnancy loss in a cohort of couples attempting to conceive. DESIGN Observational prospective cohort. SETTING Not applicable. PATIENT(S) Three hundred and forty-four couples with a singleton pregnancy observed daily through 7 postconception weeks of gestation. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Association betwe...

Comparative studies of semen characteristics in subhuman primate species should be of value in the selection of appropriate species for experiments in reproduction. In addition, basic information obtained in such studies may be helpful for the successful preservation of frozen semen and insemination. These techniques will probably be essential in the maintenance of large primate colonies. Final...

The short-term effect of gonadotrophin releasing hormone (GnRH) vaccine was evaluated in ten adult male dogs with mean weight of 8.0±1.2 kg, and age ranging between 1 and 3 years. The first group (control) comprised five intact dogs treated with normal saline, while the second group included five dogs treated with a single subcutaneous injection of 400 μg GnRH vaccine. Semen was obtained from t...

The aim of this research was to study the effect of changing female stimulus on libido and semen characteristics from young Murciano-granadina male goats submitted to intensive semen collection using females not in estrus as teasers. Males were submitted to two different sexual stimulation procedures. In the first procedure, the same doe was used as the female stimulus for three consecutive pre...

The objective of this study was to evaluate the effects of selection for increased size of testes on semen and testis characteristics. Boars from a line selected for increased size of testes at 150 d of age (TS, n = 25) and a randomly selected control line (C, n = 18) were used. Semen was collected three times per week for 3 wk (TRT1) then daily for 3 wk (TRT2) beginning when boar age averaged ...

Assisted reproductive techniques require an efficient semen collection procedure in cases of ejaculatory dysfunction. Anejaculation may be of psychogenic or neurogenic origin but can be overcome with stimulatory techniques. Penile vibratory stimulation (PVS) therapy for anejaculation has recently emerged as an alternative to rectal probe electroejaculation (RPE) and more invasive testicular pro...

The goal of this study was to investigate the reproductive profile male Senduro Goats as superior candidates based on data semen quality. experiment carried out ten kept at Singosari Animal Husbandry Service Unit in East Java, Indonesia. An artificial vagina used collect sperm. macroscopic and microscopic qualities fresh Goat sperm have been observed. Color, volume, smell, pH, viscosity were ex...
