The concept of male subfertility has evolved rapidly since 2000. This term is discussed based upon evidence relating to its first entrance into the literature, along with contemporary references to its purported incidence and prevalence. Factors affecting sperm quality are described in detail, and available data pertaining to the effects of micronutrients on spermatic parameters and resulting pregnancies are described. The first cost-efficiency analysis of the use of micronutrients vs. assisted reproductive technologies is presented. This paper also describes a therapeutic approach to males, recognizing that many potential fathers have no recourse to medical facilities to evaluate their fertility. At a time when medical dollars are either nonexistent or precious, such an approach using micronutrient supplementation may be cost-effective in developing and possibly even in developed countries.

Purpose: Infertility is defined as the inability to conceive after 1 year of unprotected intercourse, affecting approximately 15-20% of couples in Western countries. It is a shared problem within the couple; when the main issue lies with one of the partners, it is preferable to refer to "male factor" or "female factor" infertility rather than simply male or female infertility. Despite male factor infertility accounting for half of all couple infertility cases, the clinical approach to the male partner is not uniformly standardized across international guidelines.

Infertility affects 10-15% of couples worldwide, with male factors accounting for half of cases. Environmental, behavioral, and genetic problems contribute to spermatogenic failure in 30% of idiopathic male infertility cases. Other factors, such as oxidative stress (OS), cause impaired spermatogenesis, abnormal sperm morphology, and reduced motility, eventually triggering male infertility.

The production of spermatozoa, a process known as spermatogenesis, is primarily controlled by follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-driven testosterone. LH acts on the Leydig cells, stimulating steroid production, predominantly testosterone, and activating critical inter-related spermatogenesis regulatory pathways. Despite evidence that exogenous gonadotropins containing LH activity can effectively restore spermatogenesis in males with hypogonadotropic hypogonadism, the use of these drugs to treat other forms of male infertility is the subject of an ongoing debate.

Patients And Methods: In the presented report, the cause of couple infertility was a combination of a 38-year-old female and 43-year-old male with azoospermia, which was an indication for oocyte vitrification. Oocyte polar bodies and optically birefringent meiotic spindles were visualized by polarized light microscopy and their states and relative positions were used as indicators of oocyte maturation, i.

The study of the mechanism of oligoasthenospermia, which is a major cause of male infertility, has been the focus of research in the field of male reproduction. TAp73, a member of the p53 family of oncogenes, is endowed with tumor-suppressing activity due to its structural and functional homology with p53. It has been found that TAp73, plays a key role in spermatogenesis and maintaining male reproduction.
