Testicular sperm extraction (TESE) may provide spermatozoa for attempts at fertility with assisted reproduction; however, the physiological effects of TESE on testicular function are not well understood. In order to evaluate testis, 64 patients were evaluated after non-obstructive azoospermia physical examinations, serial scrotal sonography, histological analyses and evaluation success repeated retrieval attempts. At 3 months TESE, 82% had ultrasonographic abnormalities in testis suggesting...
New York City was the international epicenter of COVID-19 pandemic. Health care providers responded by rapidly transitioning from in-person to video consultations. Telemedicine (ie, visits) is a potentially disruptive innovation; however, little known about patient satisfaction with this emerging alternative traditional clinical encounter.This study aimed determine if differs between and visits.In retrospective observational cohort study, we analyzed 38,609 Press Ganey survey outcomes clinic...
Y chromosome microdeletions are associated with severe male factor infertility. In this study, the success rate of testicular sperm retrieval was determined for men deletions AZF regions a, b or c.AZF were detected by PCR 30 sequence-tagged sites within Yq emphasizing AZFa, and c regions. Semen analysis diagnostic testis biopsy extraction (TESE) findings correlated specific region deleted.A total 78 included three AZFa deletion, 11 AZFb, 42 AZFc, 16 AZFb+c six (AZFa+b+c).

We examined preoperative factors that could predict successful microdissection testicular sperm extraction in men with azoospermia and nonmosaic Klinefelter's syndrome. also analyzed the influence of hormonal therapy on retrieval rate.A total 91 attempts were done 68 Men serum testosterone less than 300 ng/dl received medical aromatase inhibitors, clomiphene or human chorionic gonadotropin before extraction. Preoperative patient age endocrinological data compared those whom procedure was not...

Abstract De novo mutations are known to play a prominent role in sporadic disorders with reduced fitness. We hypothesize that de an important severe male infertility and explain portion of the genetic causes this understudied disorder. To test hypothesis, we utilize trio-based exome sequencing cohort 185 infertile males their unaffected parents. Following systematic analysis, 29 145 rare (MAF < 0.1%) protein-altering classified as possibly causative phenotype. observed significant...

Purpose: The aim of this study was to report the successful fertility treatment men with Klinefelter syndrome using testicular sperm extraction (TESE) and intracytoplasmic injection (ICSI). Methods: A total 42 who underwent 54 TESE procedures were identified. Before TESE, patients serum testosterone levels less than 15.6 nmol/liter treated an aromatase inhibitor. Sperm retrieval rates results ICSI, including fertilization clinical pregnancy, collected. Results: Mean pretreatment FSH 33.2...

To provide fertility for men with nonobstructive azoospermia.A retrospective review of treatment results at a university infertility center was undertaken. Sixteen couples entered an attempted in vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) cycle azoospermia. Each man azoospermic, and the male factor diagnosis azoospermia made on testis biopsy 14 clinical grounds 2 men. Sperm were retrieved by testicular day oocyte retrieval. Results examinations, serum...
We establish whether a subset of infertile men have decreased serum testosterone-to-estradiol ratios and this condition can be corrected with an oral aromatase inhibitor.The 63 severe male factor infertility or hypergonadotropic hypogonadism (mean follicle-stimulating hormone 21.2 +/- 1.8) were compared those age matched, fertile, control reference group. Of the 43 azoospermic biopsy proved 20 oligospermic. The lowest (less than 20th percentile) treated 50 to 100 mg inhibitor testolactone...
Genetic abnormalities, including partial deletions of the Y-chromosome, are commonly detectable in men with non-obstructive azoospermia (NOA). NOA can be treated using testicular sperm extraction (TESE) intracytoplasmic injection (ICSI). Recent studies have shown that presence involving AZFc region do not appear to affect chance retrieving spermatozoa or a significant impact on fertilization pregnancy rates ICSI. We investigated effect Y-chromosome retrieval TESE. Eighty attempts at were...

Klinefelter's syndrome is a form of hypergonadotropic hypogonadism and infertility resulting from supernumerary X chromosome (47,XXY), with an incidence approximately 1 case in 500 phenotypic males.1,2 Some men who have chromosomal mosaicism (46,XY/47,XXY) are fertile. Men nonmosaic, or complete, usually azoospermia, only few any spermatogenesis.3,4 Intracytoplasmic sperm injection, which spermatozoon injected into ovum vitro, effective treatment for male-factor infertility. However, the...
