Fertility and Sterility, 1977
Over the past 25 years the association of varicocele with male subfertility has been repeatedly demonstrated and the beneficial effect of varicocele ligation in infertile men with oligoasthenospermia has been documented. Since the precise mechanisms by which a varicocele affects spermatogenesis are still unclear, the proper approach to the management ...

Obesity Reviews, 2016
SummaryIn the last decades, several studies evidenced a decrease in male fertility in developed countries. Although the aetiology of this trend in male reproductive health remains a matter of debate, environmental compounds that predispose to weight gain, namely obesogens, are appointed as contributors because of their action as endocrine disruptors ...

Endocrinology and Metabolism Clinics of North America, 1998
Effective treatments for extreme oligozoospermia include in vitro fertilization, recovery of sperm through epididymal sperm aspiration or testicular sperm aspiration, and direct injection of sperm through intracytoplasmic sperm injection. The clinical evaluation of and treatment options for male patients with fertility disorders are detailed in this ...

Current Urology Reports, 2018
With improvements in cancer treatment outcomes and an increase in cancer survivorship, understanding the importance of fertility preservation options prior to undergoing cancer treatment is essential. Therefore, we review herein the effect of cancer and its treatment on male fertility, the rationale for sperm cryopreservation, options for sperm ...

Fertility and Sterility, 1988
Serum estradiol (E2) levels were measured in 451 men attending an infertility clinic and 80 fertile men attending for vasectomy. The normal range of E2 levels found in fertile men was 70 to 200 pmol/l. Subfertile men had lower mean E2 levels than fertile men (P less than 0.05), but there was no relationship to obesity, cigarette smoking, age, or the ...

Around 50% of all occurrences of infertility are attributable to the male factor, which is a significant global public health concern. There are numerous circumstances that might interfere with spermatogenesis and cause the body to produce abnormal sperm.

Early in embryogenesis, cells that are destined to become germ cells take on a different destiny from other cells in the embryo. The germ cells are not programmed to perform "vital" functions but to perpetuate the species through the transfer of genetic materials to the next generation.

Male Hyperprolactinemia: Effects on Fertility
Fertility and Sterility, 1979Male hyperprolactinemia was detected in 4% (7 of 171) of infertile men. In seven patients with excessive serum prolactin concentrations, the clinical manifestations were infertility, hypogonadism, impotence, and galactorrhea and the etiologic factors were pituitary adenoma, hypothalamic dysfunction, drug use, and idiopathic.

Abstract It is just as important that the man attend the fertility appointment and is thoroughly checked over. It is estimated that male fertility is the main problem in one in three couples trying to get pregnant. Overall about 75 per cent of couples will conceive after trying for a year.
