KondracKi, S., K. GorSKi, a. WySoKinSKa and i. JoZWiK, 2014. correlation of ejaculate parameters and sperm morphology with the ejaculate volume of Pietrain boars. Bulg. J. Agric. Sci., 20: 703-709 The objective was to analyze the connection between physical ejaculate parameters and sperm morphology and the volume of Pietrain boar ejaculates. The study covered 87 ejaculates collected from 10 Pol...

Ejaculate size in seed beetles (Coleoptera: Bruchidae) is subject to both sexual and fecundity selection. We examined interpopulation variation and inheritance of ejaculate size in the seed beetle Callosobruchus maculatus (F.). There was signiÞcant variation among three populations in both body mass and the proportion of a maleÕs body mass that was transferred to females during mating. The seed...

OBJECTIVES To report our experience with transurethral resection of the ejaculatory ducts (TURED) in infertile men with symptomatic ejaculatory duct obstruction (EDO). PATIENTS AND METHODS Before surgery, all patients complained of a decrease in the volume of their ejaculate, 14 of 15 had a non-projectile ejaculation, nine had a genitourinary infection necessitating antibiotic treatment, and ...

The function of nuptial gifts has generated longstanding debate. Nuptial gifts consumed during ejaculate transfer may allow males to transfer more ejaculate than is optimal for females. However, gifts may simultaneously represent male investment in offspring. Evolutionary loss of nuptial gifts can help elucidate pressures driving their evolution. In most katydids (Orthoptera: Tettigoniidae), ma...

--To assess natural variation in ejaculate quality of male Dark-eyed Juncos (Junco hyemalis), as well as to measure any effect of experimental treatment with testosterone (T), we used cloacal massage to collect sperm samples from captive (1993) and free-ranging (1994, 1995) populations. We made three measurements of ejaculate quality in males, approximately half of which had been treated with T...

When ejaculates are costly to produce, males are expected to allocate their ejaculate resources over successive matings in a manner that optimizes their reproductive success and this may have important consequences for their mates. In seed beetles (Coleoptera; Bruchidae), ejaculates vary in size across species from weighing less than 1%, up to as much as 8%, of male body weight. Ejaculates cont...

Objectives: The aim of this prospective study was to observe immunophenotypic patterns in patients with noninflammatory chronic pelvic pain syndrome (Cat IIIB CPPS) for further description and as possible surrogate markers for diagnosis and treatment. Methods: Eighty-eight patients with a referral diagnosis of chronic prostatitis underwent fractionated urinary cultures including expressed prost...

Males of the bedbug, Cimex lectularius, traumatically inseminate females by inserting a needle-like intromittent organ (penis) through the female's abdominal wall after she has fed. We demonstrate that: (i) mating duration determines ejaculate size; (ii) a female's first copulation in a bout of copulations always lasts longer than subsequent copulations; (iii) the intromittent organ bears sensi...
