Long‐term clinical outcomes of testicular sperm extraction and intracytoplasmic sperm injection for infertile men
Purpose To find the best methods to achieve the highest pregnancy and birth rates for couples needing testicular sperm extraction (TESE)-intracytoplasmic sperm injection (ICSI). Methods Retrospectively studied were 801 patients with male factor infertility who had undergone TESE-ICSI between April, 1996 and July, 2016 and who had been categorized into four groups: obstructive azoospermia (OA)...
متن کاملSperm morphology, motility, and concentration in fertile and infertile men.
BACKGROUND Although semen analysis is routinely used to evaluate the male partner in infertile couples, sperm measurements that discriminate between fertile and infertile men are not well defined. METHODS We evaluated two semen specimens from each of the male partners in 765 infertile couples and 696 fertile couples at nine sites. The female partners in the infertile couples had normal result...
متن کاملRetinopathy of prematurity: New developments bring concern and hope.
Blindness from retinopathy of prematurity (ROP) in Australian and New Zealand is an uncommon event although 3% of <31 weeks gestation infants receive treatment for the disease. New world-wide estimates of the incidence of blindness from ROP are much higher than previously at 20 000 children annually. The impact of severe ROP can be reduced through good evidence-based care of very preterm infant...
متن کاملThe effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity. This study aimed to determine whether the recombinant human follicle-stimulating hormone (rhFSH) treatment of sperm parameters could positively affect sperm DNA and...
متن کاملCorrelation of sperm morphology and oxidative stress in infertile men
Background: Excess reactive oxygen species (ROS) in the semen is believed to affect fertility in men. Morphologically abnormal sperms and their relation to seminal oxidative stress in infertile and subfertile men are not clear. Objective: To correlate various sperm morphological defects with seminal oxidative stress in infertile and subfertile men. Materials and Methods: The study included 25 p...
