Our aim was to explore the existence of a possible relationship of sperm motility with serum 25-hydroxyvitamin D3 (25-OH VD) levels and with ischaemia-modified albumin (IMA) levels in infertile Turkish men. A total of 30 men with nonobstructive azoospermia (no spermatozoa in ejaculate), 30 men with
BACKGROUND
In patients with transient azoospermia, few sperm may be found in the ejaculate. We investigated the outcome of ICSI in patients with transient azoospermia.
METHODS
Records of patients with transient azoospermia referred during a 42 month period were reviewed. If only immotile sperm were
Azoospermia is one of the challenging disorders affecting couples who are afflicted with infertility. Human testisderived cells (hTCs) are suitable candidates for the initiation of in-vitro spermatogenesis for these types of patients. The current study aimed to assess the proliferation of hTCs
An immunologically reactive albumin-like protein (albumin) was localized, by an immunostaining technique, in the testis of infertile men (normal spermatogenesis, obstructive azoospermia) at the level of the Sertoli cells and in some cells of the germinal epithelium (secondary spermatocytes and early
Recent achievements in stem cell biotechnology, nanotechnology and tissue engineering have led to development of novel approaches in regenerative medicine. Azoospermia is one of the challenging disorders of the reproductive system. Several efforts were made for isolation and culture of OBJECTIVE
The motility of testicular derived spermatozoa reflects viability and predicts success during intracytoplasmic sperm injection. Although improvements in sperm motility are seen after incubation for extended periods, no guidelines suggest duration or media use for optimal improvement in
A number of studies have shown a relationship between transferrin levels in seminal plasma and sperm count. In the present study, the levels of transferrin, beta 2-microglobulin and albumin were measured in 171 samples of seminal plasma (50 subjects with normal sperm count; 32 with azoospermia; 49
Azoospermia is frequently due to an obstruction of genital pathways. In this work, concerning 22 patients submitted to surgical investigation for sterility, we made a systematic histological investigation of the lesions, and we studied the motility of epididymal spermatozoa. We observed with an
The expression of human beta2-microglobulin (beta2m) on human spermatozoa cell surface was investigated by cytotoxicity and immunofluorescence tests. beta2m was also found in human seminal fluid by use of immunochemical techniques. Seminal fluids obtained from couples with infertility problems were
To determine whether the change in sperm parameters in subfertile hypoandrogenic men treated with anastrozole is correlated to the magnitude of increase in testosterone (T) to estrogen ratio in men responding to treatment.
