Fertility Preservation in Pubertal and Pre-Pubertal Boys with Cancer.

Children diagnosed with cancer continue to have improved survival due to advances in effective treatment options. Increased attention is therefore now focused on quality of life issues once they are cured. Fertility preservation is of paramount concern since gonadotoxic treatments, especially radiation and chemotherapy, often impair future fertility.

Bulbocavernosus muscle area as a novel marker for hypogonadism.

Objective: Late-onset hypogonadism, or androgen deficiency in the aging male, is a significant cause of morbidity in older men. Many men in the low normal or equivocal range for low testosterone level exhibit signs and symptoms of hypogonadism. Serum testosterone is an imperfect maker for hypogonadism as symptoms vary greatly within the low to low normal range in addition to variations among testosterone assays.

Imaging and angiography in male factor infertility.

Ultrasound imaging and angiography play a crucial role in the diagnosis and treatment of men with subfertility. The most commonly used imaging modality is ultrasound (US), which can be used for diagnostic purposes or to aid in treatment. Scrotal US can be used to document varicoceles in subfertile men in the context of difficult examination or for confirmation before treatment.

Penile Doppler ultrasound predicting cardiovascular disease in men with erectile dysfunction.

Cardiovascular disease is a major cause of morbidity and mortality in the USA. Traditional risk factors such as obesity, physical inactivity, and diet are used to screen for cardiovascular disease. However, these risk factors miss a significant population who are at risk for future cardiac events.

Penile sonoelastography for the localization of a non-palpable, non-sonographically visualized lesion in a patient with penile curvature from Peyronie's disease.

Introduction: Sonoelastography is an emerging ultrasound-based technique that allows characterization of tissue stiffness.

Aim: The aim of this report is to present a case of significant penile curvature with a non-palpable, non-sonographically visualized plaque that was demonstrable with sonoelastography.

Methods: A 60-year-old male presented with significant left penile curvature during erections.

Spectral Doppler sonography: a noninvasive method for predicting dyspermia.

Objectives: Sonography is a noninvasive, office-based diagnostic tool often used for evaluation of subfertile men. Previous studies have suggested that a resistive index (RI) greater than 0.6 is associated with impaired spermatogenesis.

Office ultrasound for the urologist.

Imaging of the genitourinary tract is essential in the workup of the majority of the conditions seen daily by urologists. The use of ultrasound in the office provides a safe, low cost, and efficient way for the clinician to evaluate the patient in real time. Ultrasound can allow for bedside diagnosis in many conditions and assist in treatment planning.

Long-term effects of cryopreservation on human spermatozoa.

We evaluated the long-term effects of cryopreservation on spermatozoa of men with testicular cancer, lymphoma, and benign conditions. No statistically significant decrease in semen parameters was noted. Duration of follow-up was up to 5 years and mean follow-up was 2 years.

Normal semen parameters in cancer patients presenting for cryopreservation before gonadotoxic therapy.

Similar sperm qualities in men with and without cancer were found. Patient and physician awareness and early referral for sperm banking are essential in preserving fertility potential in men with malignancies.

Cryopreservation of sperm: indications, methods and results.

Purpose: We review the history of the cryopreservation of human sperm. The current methods of cryopreservation and indications are highlighted, and the success rates of the various uses of cryopreserved sperm are reviewed. Potential adverse sequelae of human cryopreservation are also discussed.
