Comparison between sperm treated with pentoxifylline and 2-deoxyadenosine using hypo-osmotic swelling test.

Pregnancy Outcome with Intrauterine Insemination in Patients with Unexplained Recurrent Abortion Whose Partners Have Abnormal Hypo-Osmotic Swelling Test

Background: Recurrent abortion is defined as three or more consecutive pregnancy losses. We aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. We also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...

Outcome of ICSI Cycles using Pentoxifylline or Theophylline to Identify Viable Spermatozoa in Patients with all Immotile Spermatozoa

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...

Correlation between Different Patterns of Hypo-Osmotic Swelling and Sperm Functional Tests

Should We Perform Semen Analysis, DNA Fragmentation, and Hypo-osmotic Swelling Tests together?

Semen analysis, sperm DNA fragmentation (SDF) and hypo-osmotic swelling test (HOST) are usually performed for the evaluation of sperm fertilizing ability. There are some debates over the necessity of SDF and HOST incorporation in male infertility work-up.Semen of 77 men was evaluated by SDF and HOST through three semen analyses. Sperm parameters were arranged into different categories: <5%, 5-1...

P-77: HOST Patterns and Sperm Quality

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...
