We retrospectively analyzed 6,360 artificial insemination cycles of husband's semen through intrauterine insemination (AIH-IUI) or artificial insemination with donor semen through intrauterine insemination (AID-IUI) in patients with infertility between August, 1998 and August, 2010. The relationship between processed total motile sperm count (PTMS) and pregnancy outcome was determined. The study was divided into 6 groups according to PTMS. Group 1: ≤ 2.0 million, Group 2: 2.1-4.0 million, Group 3: 4.1-6.0 million, Group 4: 6.1-8.0 million, Group 5: 8.1-10.0 million, and Group 6: >10.0 million. There was no statistically significant difference in age, duration of infertility, unilateral tubal patency, induced ovulation, and single IUI or double IUI between the 6 groups in both AIH-IUI and AID-IUI. The total clinical pregnancy rate of AIH-IUI was 10.81 % and AID-IUI was 27.52 %. Among the 6 groups, the clinical pregnancy rate was the lowest in Group 1 (P < 0.05) in both AIH-IUI and AID-IUI. With the increased PTMS, the clinical pregnancy rate of IUI was improved. However, a statistical difference between groups was only observed for Group 1. When PTMS is ≤ 2 × 10(6) the clinical pregnancy rate of IUI is significantly decreased. In this case in vitro fertilization (IVF) should be adopted.

The use of pseudoephedrine, an alpha agonist, for the treatment of retrograde ejaculation is well-known, however, there is no clear consensus from the literature regarding its efficacy and treatment p...
Immotile sperm is a rather frequent problem encountered in IVF patients. Treatment is usually based on inducing motility with pentoxyphylline (PXN) followed by ICSI. However, fertilization...
The (motile sperm organelle morphology examination) MSOME allows the detection of sperm vacuoles that seems to be related to sperm DNA damage. The investigators hypothesized that couples ...
To compare motile sperm extraction rate between microTESE and conventional TESE in 18-50 years-old men with non obstructive azoospermia.
The purpose of this study is to evaluate semen for changes following radiation treatment with proton beam radiotherapy alone. The semen samples will be compared for sperm count, sperm move...

The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.
A count of SPERM in the ejaculum, expressed as number per milliliter.
An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).
A form of psychotherapy involving the husband and wife and directed to improving the marital relationship.
A condition in which the percentage of progressively motile sperm is abnormally low. In men, it is defined as <25% rapid motility or <50% progression in a semen sample (World Health Organization, 1992).
