Platelet-activating factor (PAF; 1-O-alkyl-2-O-acetyl-sn-glycero-3-phosphorylcholine) is a potent signaling phospholipid with pleiotropic biologic activities. Since its discovery more than 30 years ago, numerous investigators have documented its presence in a variety of tissues. PAF and its receptors are present both in somatic and reproductive cells. PAF appears to be critical for ...

With aspiration of sperm directly from the epididymis (MESA) or extracted from the testis (TESA) and intracytoplasmic sperm injection, it is possible to provide men who are incapable of producing viable sperm in an ejaculate the ability to overcome this severe sperm defect and produce a successful pregnancy. In our ...

Embryonic mortality in mammals is typically thought to result from 'female factor' infertility. There is growing evidence, however, that the status of sperm chromatin (DNA) at the time of fertilisation can also influence embryonic survival. During the final stages of spermatogenesis (spermiogenesis) a number of unique biochemical, morphological and physiological ...

BACKGROUND: Leukocytes are a frequent finding in seminal plasma of infertile males with abacterial inflammation. We evaluated the effects of treatment with rofecoxib, a cyclooxygenase-2 inhibitor, on sperm quality and pregnancy rate after intrauterine insemination (IUI) or monitored intercourse. METHODS: We selected 47 infertile patients referred to our sterility centre ...

Many of the world's cat species face growing threats to their continued survival in nature. For some species, managed captive populations may provide a reservoir for future reintroduction or genetic augmentation. Because most zoo populations are derived from small founder sizes and are subject to loss of genetic variation over ...

A very rare case of successful pregnancy was reported using testicular sperm from a severely infertile man given the treatment of hCG in advance. Prior to treatment, no sperm were present in the ejaculate and testicle. hCG was administrated to the patient for spermatogenesis. After a period of hCG treatment, ...

Globozoospermia is a rare (incidence <0.1%) but severe disorder in male infertility. Total globozoospermia is diagnosed by the presence of 100% round-headed spermatozoa lacking an acrosome. It is still unclear whether patients whose ejaculate contains both normal and globozoospermic cells (partial globozoospermia) suffer from a variation of the same syndrome. ...

Sporulation in Saccharomyces cerevisiae is a highly regulated process wherein a diploid cell gives rise to four haploid gametes. In this study we show that histone H4 Ser1 is phosphorylated (H4 S1ph) during sporulation, starting from mid-sporulation and persisting to germination, and is temporally distinct from earlier meiosis-linked H3 S10ph ...

The association of occipital encephalocele, cleft palate, postaxial polydactyly, polycystic kidneys, and hepatic cysts is well known as Meckel-Gruber syndrome (MGS). Nowadays, the diagnosis of MGS is usually performed prenatally by ultrasound findings. MGS was previously described following in vitro fertilization. We report a case of MGS diagnosed at 17 ...
