OBJECTIVE To evaluate cost per delivery using two different initial approaches to the treatment of postvasectomy infertility. DESIGN Model of expected costs and results in the United States in 1994. SETTING Men with postvasectomy infertility, evaluated and treated at centers with experience in vasectomy reversal or sperm retrieval and ICSI. PATIENT(S) Men with postvasectomy infertility, w...

Given a permutation π, the application of prefix reversal f (i) to π reverses the order of the first i elements of π. The problem of Sorting By Prefix Reversals (also known as pancake flipping), made famous by Gates and Papadimitriou (Bounds for sorting by prefix reversal, Discrete Mathematics 27, pp. 47-57), asks for the minimum number of prefix reversals required to sort the elements of a giv...

BACKGROUND Chronic testicular pain, or "chronic orchalgia," is defined as testicular pain 3 months or longer in duration that significantly interferes with the daily activities of the patient. For patients failing to respond to conservative treatment, microsurgical denervation of the spermatic cord, epididymectomy, and vasovasostomy have all shown a degree of relief. However, these are all inva...

This study investigated the effect of sildenafil citrate on micro-recanalization and neovascularization, which were previously demonstrated in a rat model using biodegradable grafts (BGs) for vas deferens reconstruction. A total of 24 male rats underwent bilateral vasectomy with removal of a 0.5-cm vasal segment and were randomly assigned to four groups. Groups 1 and 2 underwent immediate vasov...

Male reproduction and male contraception form an important spectrum within men’s health. In this issue’s Views Reviews, four author groups detail new developments in vasectomy clinical practice guidelines, emerging investigational techniques the fields of hormonal nonhormonal contraception, useful paradigms for patient care when deciding between sperm extraction with vitro fertilization reversa...

Abstract Introduction Surgery for male fertility is ergonomically demanding secondary to the tedious and lengthy nature of surgeries performed. The standard operating microscope places surgeons in uncomfortable positions including a “heads down” posture which has been demonstrated predispose microsurgeons cervical strain chronic pain. 4K-3D exoscope eliminates need eyepieces allowing up” postur...

objective: vasectomy, though in some cases are being confronted with irreversibility, has been accepted as an effective contraceptive method. it is estimated that near 2-6% of vasectomised men ultimately show a tendency to restore their fertility. in some cases, vasectomy has been considered as an irreversible procedure due to many post-vasectomy complications causing this debate. the aim of pr...

We report paleomagnetic results from four overlapping stratigraphic sections (55 flows) through the lava pile in Tjörnes peninsula (North Iceland). The initial aim of our study was to check the existence of intermediate directions previously interpreted as belonging to the Matuyama-Brunhes geomagnetic reversal (MBR), and complete this record with ThellierThellier paleointensity determinations a...

Background: This study was done to evaluate the no scalpel technique (NSV) for vasectomy in camp approach and establish recommendations for health education and special attention to issues affecting compliance to post vasectomy instructions and post vasectomy semen analysis (PVSA). Materials and Methods: This was a prospective study of various aspects of NSV like details of procedure, character...
