Indomethacin and oxaprozin lower seminal prostaglandin levels but do not influence sperm motion characteristics and serum hormones of young healthy men in a placebo-controlled double-blind trial
seminal prostaglandin levels sperm motion characteristics serum hormones young healthy men
2009/2/23
To evaluate the influence of indomethacin and oxaprozin on reproductive function in healthy young men, 34 volunteers with normal semen parameters were recruited. In a randomized double-blind design,...
Influence of photoperiod, ambient temperature and melatonin on testosterone synthesis and release during reproductive maturation in male deer mice
photoperiod ambient temperature melatonin testosterone synthesis reproductive maturation male deer mice
2009/2/23
Four experiments were designed to investigate the influence of photoperiod and other environmental factors on androgen production and reproductive maturation in deer mice. Male prairie deer mice (Pe...
Testicular blood flow in young and old rats and influence of hCG
testis blood flow hCG rat aging
2009/2/20
To evaluate the influence of age, testicular capillary blood flow (TCBF) was measured, using the microsphere technique, in rats 3 to 24 months old, under basal conditions and after hCG stimulation (...
Influence of estradiol on accessory reproductive organs in the castrated male rat. Effects of bromocriptine and flutamide
estradiol accessory reproductive organs castrated male rat
2009/2/19
Estradiol partially maintained the weights of the dorsolateral prostate and seminal vesicles in castrated adult male rats. One group of animals received subcutaneous injections of estradiol (0.01 ...
Influence of Testicular Steroids on Thyrotropin Releasing Hormone-induced Prolactin Release in Mature Rams
testicular steroids prolactin prolactin secretion
2009/2/18
Prolactin (PRL) concentrations were measured in serum of intact rams, castrate rams, and steroid-treated castrate rams to determine whether testicular steroids influence PRL secretion in this sp...
The influence of castration on pharmacologically induced penile erection in the cat
Testosterone vasoactive agents cAMP cGMP
2009/2/18
The purpose of this study was to investigate the in vivo effects of intracavernosal injections of adrenomedullin (ADM), calcitonin gene-related peptide (CGRP), nociceptin, vasoactive intestinal po...
We have previously demonstrated that conditioned medium from testicular macrophages stimulates testosterone production by Leydig cells. It was also reported that conditioned medium from macrophage...
Influence of centrifugation regimes on motility, yield, and cell associations of mouse spermatozoa
Cryopreservation mechanical sensitivity damage recovery
2009/2/17
Mouse sperm are exceptionally sensitive to mechanical forces associated with pipetting and mixing. This characteristic raised the question of the sensitivity of mouse sperm to centrifugation, a st...
The influence of semen analysis parameters on the fertility potential of infertile couples
Semen analysis conception rate survival analysis
2009/2/17
The objective of this study was to investigate the relationship between couples' fertility potential and several parameters of semen analysis (from a single semen sample/male partner) in a cohort ...
Anti-bull sperm monoclonal antibodies：II. Binding changes during capacitation and influence on sperm-zona interactions in vitro
Bull sperm sperm-zona binding capacitation
2009/2/16
Anti-bull sperm monoclonal antibodies (mAbs), generated against intra-acrosomal and surface antigens, were evaluated for their functional significance. In experiment I, the influence of mAbs on the bo...
Influence of semen collection method on ejaculate characteristics in the common marmoset, Callithrix jacchus
Spermatozoa electroejaculation vaginal washing artificial insemination
2009/2/16
A source of normal spermatozoa (sperm) is required for many andrological and reproductive studies. Ideally the method used for semen collection should be repeatable and reliable but should not influ...
Secreted products and extracellular matrix from testicular peritubular myoid cells influence androgen-binding protein secretion by Sertoli cells in culture
Cocultures parabiotic cultures dibutyryl cyclic AMP Sertoli cells peritubular myoid cells
2009/2/13
Metabolic cooperation mediated by secreted factors between Sertoli cells and peritubular myoid cells has been well documented. We have confirmed that factors secreted by peritubular myoid cells mo...
Influence of bovine follicular and oviduct fluids on sperm capacitation in vitro
bovine follicular oviduct fluids sperm capacitation
2009/2/7
The ability of bovine follicular fluid (FF) and oviduct fluid (ODF) to capacitate sperm was determined. At concentrations of greater than 20%, both FF and ODF capacitated sperm within 4 hours, but a...
