CONTEXT: Despite the recent declines in rates of teenage pregnancy, relatively little is known about the few programs that have been successful in reducing adolescent pregnancy. METHODS: Six agenc...
Multivariate discriminant analysis was used to evaluate the usefulness of computer image analysis of sperm movement characteristics and differential patterns of sperm tail swelling after hypoosmot...
Doppler sonography is considered a reliable method for detecting reflux due to venous valvular incompetence, which occurs in varicocele. It is, however, a matter of debate whether the characteristic...
Tubular boundary tissue and seminiferous epithelia were evaluated stereologically in testes from 28 men aged 20 to 48 years and 28 men aged 50 to 90 years. Testes obtained at autopsy within 15 hours...
A series of semen samples that had been recorded on motion picture film, then evaluated via standard visual techniques by a number of well established fertility clinics (Van Duijn et al (1971)), w...
A 51-year-old man with previously diagnosed bilateral anorchia was shown by endocrine investigation of his hypophyseal-gonadal axis to have functioning testicular tissue. The implications of endocri...
Recently, there is increasing evidence suggesting that oxidative sperm DNA damage is closely associated with impaired sperm function and male infertility. 8-Hydroxydeoxyguanosine (8-OHdG) is consi...
Sperm cells can be retrieved directly from the testis (testicular sperm extraction [TESE] procedure) and used for intracytoplasmic sperm injection (ICSI), circumventing underlying spermatogenetic ...
A stereological study of the development of the mouse prostate was undertaken between the second week of postnatal life and maturity. The aim was to quantify the progressive changes in the size and ...
We investigated the effect of follicle-stimulating hormone (FSH) administration on the ultrastructure of spermatozoa in order to evaluate the potential of FSH therapy for improving sperm quality. Fo...
The binding patterns of 11 recently commercially available fluorescein isothiocyanate-conjugated lectins that have been uncharacterized or undercharacterized in rat testes and/or have an unknown or ...
The objective of this study was to investigate the association of rapid and linear progressive motility in seminal and Percoll-separated sperm with the outcome of intrauterine insemination (IUI) and...
This study was undertaken to compare a new fluorescent stain-based computer-assisted semen analysis (CASA) system (IDENT) for determining human sperm concentration to the manual hemacytometric met...
This paper concerns the mathematical evaluation of sperm quality as examined by electron microscopy. Proceeding with a Bayesian technique, we have developed a formula considering all statistical pos...
The authors studied hyperactivated motility of human spermatozoa as a method of evaluating capacitation by examining its relationship to results of zona-free hamster oocyte sperm penetration assays ...
