Priapism is a poorly understood disease process with little information on the etiology and pathophysiology of this erectile disorder. One group of patients with a high prevalence of priapism is men with sickle-cell disease. Establish an in vivo transgenic sickle-cell mouse model to study the pathophysiology of sickle-cell disease-associated priapism.
Transgenic sickle-cell disease mice, expressing human sickle hemoglobin, were utilized. Three groups of mice were used: Two age groups of each cohort of mice were utilized: Histological trichrome stain to measure ratio of collagen to smooth musclepenile hydroxyproline content collagen contentand transmission electron microscopic analysis of WT, Hemi, and Sickle mice penes, as well as in vivo erectile responses [change in intracavernous pressure ICP ] to cavernous nerve stimulation CNSwere determined.
The morphometric changes of the penis and exaggerated in vivo erectile responses support the use of this transgenic sickle-cell disease animal model to study the pathophysiological mechanisms involved in sickle-cell disease-associated priapism. Priapism is "Yones kutlu wife sexual dysfunction" as an erectile disorder, in which erection persists uncontrollably without sexual purpose [ 1 ].
The mechanisms involved in development of priapism are poorly characterized; therefore, medical management of priapism represents a therapeutic challenge to

In the penis of men with ischemic priapism, the corporal bodies and vascular endothelium are exposed to intermittent episodes of anoxia. Thus, cellular, molecular and morphologic changes are activated, which often become maladaptive and contribute to progressive erectile dysfunction ED.

Conventional treatments are largely reactive, usually administered after a single episode of priapism has already occurred. Potential therapeutic targets aimed at preventing recurrent ischemic priapism have been proposed; however, they lack a mechanism-based approach and thus are largely ineffective [ 1 — 3 ].
To date, the only animal models to study the pathophysiology of priapism utilize direct injection of erectogenic agents and knockout mice that manifest priapism phenotypes [ 4 — 9 ].
These early studies have provided great understanding of the pathophysiology of priapism; however, limitations to these initial reports are related to the lack of utilization of animal models that fit with the relevant pathogenic associations of priapism, such as sickle-cell disease. One category of patients with a high prevalence of recurrent priapism is
Yones kutlu wife sexual dysfunction with sickle-cell disease.
The identification of genetic variables or molecular mechanisms that precondition the sickle-cell penile vasculature to respond abnormally to any degree of sexual stimulus is unclear.

Early reports have suggested that transgenic sickle-cell mice have episodes of priapism; however, the measurement of erectile function was not critically evaluated, and thus the conclusion is not valid [ 13 ].
Recently, Mi et al.
The present study was designed to characterize the morphological changes that occur in the penis and the in vivo erectile responses to neurogenic stimulation in a transgenic sickle-cell disease mouse model. The establishment of an in vivo animal model and vigorous preclinical analyses are imperative in order to ultimately study the pathophysiology of sickle disease-associated ischemic priapism. Transgenic sickle-cell Sickle mice with knockout of all mouse hemoglobin genes and expressing exclusively
Yones kutlu wife sexual dysfunction sickle hemoglobin were developed at Lawrence Berkeley National Laboratory [ 1415 ].
A breeding colony at the National Institutes of Health NIH generated animals for this study by mating sickle-male mice to hemizygous females approximately 15 generations. Additional control animals were hemizygous Hemi littermates, which have anemia and increased oxidative stress but no sickle deformation [ 14 ].
All were males ages 4 to 6 months old, except a series of retired breeder males 18 to 22 months old to determine the effects of aging. Mice were pathogen free and received routine NIH rodent chow and water. Studies were approved by the animal care and use committees of Johns Hopkins Medical Institutions.
For measurement of collagen to smooth muscle ratio fibrosis scalean independent pathologist blinded as to tissue group, graded on a scale of 1 least to 5 severe the amount of increase in collagen to smooth muscle ratio. After fixation, the samples were cyroprotected and prepared for transmission electron microscopic analysis as previously described [ 17 ]. Caveolae were counted by three independent blinded observers who used the "Yones kutlu wife sexual dysfunction" photographs.
Penile collagen content was quantitated by measuring the total hydroxyproline content of the penis. Penile hydroxyproline concentration was determined spectrophotometrically as previously described [ 19 ]. Hydroxyproline in the hydrolysate was assessed colorimetrically at nm with p -dimethylaminobenzaldehyde.
Hydroxyproline content was computed as micrograms of hydroxyproline per penis and indexed to body weight [ 19 ]. Induction of anesthesia was achieved by placing the animal in a jar containing gauze soaked with isoflurane.
The mice were then intubated and placed on a thermoregulated surgical table. Heart rate was determined from the systolic pressure pulses with a tachometer Biopac. MAP was measured in only a small cohort of mice from each group. The shaft of the penis was freed of skin and fascia, and by removing part of the overlying ischiocavernous muscle, exposure of the right crus was performed. The bladder and prostate were exposed through a midline abdominal incision. The right major pelvic ganglion and cavernous nerve were identified posterolateral to the prostate on one side, and an electrical stimulator with a stainless steel bipolar hook was placed around the cavernous nerve.
ICP was measured with a pressure transducer connected to a data acquisition system Biopac for continuous measurement of ICP. Each mouse underwent CNS at a frequency of 15 Hz and pulse width of 30 ms. The application of 1, 2, and 4 V was used in the current protocol to achieve a significant and consistent erectile response.
Yones kutlu wife sexual dysfunction duration of stimulation was approximately 30 seconds, with rest periods of 2—3 minutes between subsequent stimulations.
This procedure has been previously described [ 20 ]. Comparisons between baseline variables in WT, Hemi, and Sickle mice were performed using paired or unpaired t -tests, as appropriate. Comparisons between groups were made using anova analysis with repeated measures and Neumann—Keuls post hoc test for multiple group comparisons.
Statistical calculations were performed using GraphPad Prism version 5. The final sequelae of chronic anoxia and ischemia of priapism is resultant severe corporal smooth muscle and endothelial damage and widespread necrosis [ 21 ].
In the first series of experiments, WT, Hemi, and Sickle mice penes were subjected to histological and electron microscopic analysis to determine if Sickle mice penes had end-organ changes consistent with the morphometric changes that occur in penes of men with ischemic priapism.
These data suggest that Sickle mice penes have increased hydroxyproline content and ratio of collagen to smooth muscle fibrosis of the penis Figure 1.

There was sickle "Yones kutlu wife sexual dysfunction" in the corporal sinusoids of Sickle mice penes Figure 2E and increased collagen deposition Figure 2E. In Sickle mice corporal sinusoids, there was evidence of endothelial breakdown with increased adherence of red blood cells RBC to the lining of the endothelium lining the corporal sinusoids Figure 2F.
Images are representative of three to four penile samples. To further evaluate the integrity
Yones kutlu wife sexual dysfunction the corporal endothelium in WT, Hemi, and Sickle mice penes, we qualitatively studied prominent changes in ultrastructure by electron microscopy Figure 3.
The caveolae appeared as noncoated plasma-lemmal vesicles with a round lumen of up to 50— nm in diameter Figure 3. Caveolae were prevalent in WT and Hemi mice penile sinusoids in both the luminal and abluminal sides of "Yones kutlu wife sexual dysfunction" cells Figure 3A, B. However, Sickle mice penes displayed increased numbers of vacuoles with a less vesicle-shaped appearance Figure 3C.
These findings suggest that formation and stability of caveolae are altered by sickle-cell disease. Ultrastructure of the endothelium using transmission electron microscopy in wild type WT Aheterozygous Hemi; Band transgenic sickle-cell Sickle; C mice penes.
Measurements were made in blinded fashion. Images are representative of four penile samples. In the next series of experiments, erectile responses to CNS were conducted to evaluate in vivo erectile physiology and determine if the Sickle mice displayed a priapic phenotype Figure 4. These data establish in vivo evidence of priapism in Sickle mice.

These data suggest that as Sickle mice age, they lose their priapism phenotype and develop ED, which is consistent with the natural course of disease in patients with sickle-cell disease-associated priapism.

There were no visually obvious morphologic abnormalities in the aged sickle-cell mice penes, such as megalophallic changes, gross necrosis, or changes in gross penile structure. However, no histological microscopic analyses were obtained. The results of the present study show that transgenic Sickle mice penes have severe end organ damage increased collagen deposition and endothelial destruction consistent with morphometric changes that occur in penes of men with ischemic priapism.
Moreover, we also demonstrate that Sickle mice have increased frequency of erections pre- and post-CNS. Importantly, these mice do develop ED as they age, suggesting that the priapism phenotype does abate with increasing age consistent with the human sickle-cell phenotype. Priapism is associated diverse disease states, and a number of clinical contexts have risk associations for developing the disorder.
Etiological categories include trauma, neurological conditions multiple sclerosis, spinal cord tumor with compressionhematologic
Yones kutlu wife sexual dysfunction sickle-cell disease, thrombophilia, and thalassemiamalignancies, intracavernous injection therapy prostaglandin E 1papaverine, and combination therapyas well as idiopathic circumstances [ 12 ].
Low-flow ischemic priapism is more "Yones kutlu wife sexual dysfunction" than high-flow nonischemic priapism [ 1 ]. The former is painful, and blood—gas analysis reveals hypoxia. Ischemic priapism is characterized by hypoxia, hypercapnia, and acidosis [ 22 ].
The overall incidence of priapism ranges from 0. The estimation of incidence rates of priapism also depends on the population of patients under study. One category of patients with a high prevalence of recurrent priapism is men with sickle-cell disease. A higher prevalence of ED is found in sickle-cell patients that suffer with recurrent priapism [ 1025 ]. A
Yones kutlu wife sexual dysfunction investigation reported that African-American men with sickle-cell disease and ischemic priapism give a history of prior events; however, few ever receive education regarding the emergent nature of the condition, and thus present in a delayed fashion [ 26 ].
The precise mechanism of priapism in patients with sickle-cell disease remains elusive.
The assumed mechanism is that normal erection decreases the oxygen tension in the corpora cavernosa, predisposing to erythrocyte sickling, which leads to penile closed compartment syndrome.
However, the precise molecular mechanisms that precondition the sickle-cell penile vasculature to respond greater to any degree of an erectogenic stimulus are unclear. Therefore, the development and characterization of a transgenic sickle-cell disease mouse model is imperative and the
Yones kutlu wife sexual dysfunction of this study.
In this study, we show that young adult sickle-cell mice have episodes of enhanced erectile responses to a neurogenic-stimulus with increased frequency of erectile episodes before and after CNS. These in vivo erectile responses are consistent with a priapism phenotype. Importantly, they have an end organ change that are consistent with that of sickle-cell disease patients with recurrent ischemic priapism, and that is associated with increased fibrosis of the penile vascular bed.
An important observation in this study is the development of ED in sickle-cell mice as they age, which is also consistent with the natural evolution of sickle-cell patients with recurrent ischemic priapism.
Chronic anoxia and ischemia of priapism results in severe smooth muscle damage, widespread necrosis, as well as destruction of the endothelial lining as determined by electron microscopy in men suffering from ischemic priapism [ 21 ]. In the present study, we found similar electron microscopic findings in Sickle mice penes. Sickle mice penes had increased smooth muscle hypertrophy and increased basement membrane in the corporal sinusoids consistent with fibrosis.
