Artificial insemination (AI) subfertility is an indication of failure of AI with frozen-thawed sperm classified as normal by conventional semen examination. Recently, 8 AI-subfertile Japanese Black cattle (S1-S8) were identified using the routine AI test or in vivo fertilization test, which included AI with frozen-thawed sperm of superovulated females and subsequent non-surgical recovery of pre...

Background: Following the expansion of human infertility, different procedures have been utilized for separation of normal sperm during ICSI (Intra cytoplasmic sperm injection). Hypo-osmotic swelling test (HOST) is one of the tests which have been introduced for assessment of integrity of sperm membrane when confronted with hypo osmotic condition. This test may also reflect intracellular organe...

The post-coital test evaluates the penetration of spermatozoa into cervical mucus; it relies on subjective measurements and therefore lacks precision. Enzymatic liquefaction of cervical mucus allows sperm concentration to be measured in post-coital test samples, but the reliability of such measurements is not known. Donor cervical mucus was used as a model to test the accuracy and sensitivity o...

Background: Intra-cytoplasmic sperm insemination, the ICSI, is considered as the one most routine treatment of male infertility. Although the genetic inheritance of an individual is based on the genetic contribution from both the oocyte and sperm, considering the fact that ICSI by passes all the barriers to natural fertilization much emphasis was given to oocyte quality to improve the ICSI outc...

Sperm motility is an important parameter for success in intracytoplasmic sperm injection (ICSI) treatment. The sperm motility is due to its tail. If the sperm is not moving, it could be dead or alive. Normal live births have been obtained after ICSI with immotile sperm [1,2]. Various procedures have been applied to pick viable sperm for ICSI including, hypo-osmotic swelling (HOS) test [3], addi...

Background In the situation of an acute coronary occlusion, the myocardium supplied by the affected artery becomes ischemic. This part of the myocardium is at risk of developing infarction unless reperfusion occurs, and is therefore referred to as the myocardium at risk (MaR). Myocardium at risk and infarct size can be used to calculate myocardial salvage when evaluating efficacy of interventio...

Background Infertility is one of the most common and important subjects in today’s obstetrics and gynecology. Immunological factors such as the presence of antisperm antibodies (ASA) are challenging etiologies for infertility. This study was performed to determine the correlation between the type of sexual practices (oral‚ anal and vaginal during menstruation) and the ASA levels in semen and in...

Childbearing pattern has a mutual culture-based relationship with marital satisfaction. The present study aimed to compare the childbearing pattern of women with marital satisfaction and those with marital dissatisfaction in Tehran, Iran. This comparative study was conducted on 196 females during 2015-2016. The participants were divided into two groups of marital satisfaction (Mar-S; n=98) and ...
