teratozoospermia/phosphatase

The four isoforms of serine/threonine phosphoprotein phosphatase 1 (PP1), derived from three genes, are among the most conserved proteins known. The Ppp1cc gene encodes two alternatively spliced variants, PP1 gamma1 (PPP1CC1) and PP1 gamma2 (PPP1CC2). Global deletion of the Ppp1cc gene, which causes

BACKGROUND Abnormalities of spermatogenesis are associated with numerous diseases and aging. The objective of this study was to investigate the impact of hypothyroidism on human spermatogenesis and different sperm function tests. METHODS Twenty-five hypothyroid men and 15 normal individuals were

Semen qualities were studied in workers with an average age of 30 years and occupationally exposed to lead in a printing press. Another sample with the same average age but not exposed to lead were taken as control subjects. The average lead content in blood and seminal plasma of the exposed group

Effect of cyclophosphamide administration (100 mg/kg body weight, ip, for 5 consecutive days) was studied on albino rat testis and epididymidis after 3 and 6 weeks of treatment. Cyclophosphamide decreased testis and cauda epididymidal weights, sperm count, motile and viable spermatozoa and increased

OBJECTIVE To analyze the relation between recurrent miscarriage and routine semen parameters. METHODS We compared the semen parameters of normal healthy men with those of the spouses of recurrent miscarriage women through 1: 1 age-matched case-control study. RESULTS Compared with the healthy

OBJECTIVE To determine any correlation between sperm chromatin stability under sodium dodecyl sulfate (SDS), and SDS-ethylendiamine tetraacetic acid (SDS and EDTA) conditions with levels of corrected seminal fructose, obtained multiplying logarithm of sperm count by seminal fructose concentration,

210 males with idiopathic oligozoospermia or oligo-astheno-teratozoospermia were treated with tamoxifen (2 X 10 resp. 2 X 20 mg daily) over a period of five months. Investigations which were performed concomitantly revealed no significant changes in body weight, blood pressure, blood sedimentation

The effects of estradiol benzoate (E2B) at a dose of 50 micrograms/day per rat for 7, 15 and 24 days on some androgenic parameters, viz. organ weights including those of pituitary, succinate dehydrogenase, acid phosphatase, fructose, cholesterol and protein of epididymis, vas deferens, accessory

Four sexually mature boars were used in two different experiments. In Experiment I, two boars were injected once subcutaneously with atropine and, ejaculates were collected after 30, 60 and 90 min. In Experiment II, each boar was injected weekly with 25, 37.5 and 50 mg of atropine, and ejaculates

1. The major objective of this study was to examine the influence of 24-h storage of semen at low temperature on semen characteristics and fertilising ability of spermatozoa in two native breeds (Kadaknath-KN, Aseel Peela-AP) and White Leghorn (WL) chicken. 2. Various physical and biochemical

The aim of this study was to use biochemical markers to evaluate the quality of fresh and cryopreserved semen from the arctic fox (Vulpes lagopus). Twenty-three manually collected ejaculates were analysed for the main indicators of semen quality (sperm concentration and ejaculate volume). Sperm

42 subfertile male ambulatory patients were treated with Proviron. Moderate oligoastheno-teratozoospermia was the most common injury in sperm analysis. The treatment did not change the amount of plasma FSH, testosterone or prostate phosphatase. Acid phosphatase and citric acid of semen showed an

The epididymis is essential for sperm development and maturation, and, subsequently, the ability of spermatozoa to penetrate and fertilize the female gamete. Functional differences in segments of the long tubule are reflected by histological differences among epididymal regions. The feline
