REVIEW
Ryan C Owen, Benjamin J McCormick, Bradley D Figler, Robert M Coward
A dilation of the pampiniform venous plexus in the scrotum above the testicle, called a varicocele, affects approximately 15% of the general male population. While the majority is asymptomatic, pain results in up to 10% of cases of varicoceles. The pain associated with varicoceles is typically mild and is described as heavy, achy, or dull-and is usually isolated to the testicle or spermatic cord. Guidelines clearly recommend varicocele repair in males with varicoceles, infertility, and an abnormal semen analysis...

REVIEW
A S Rex, J Aagaard, J Fedder
Sperm DNA Fragmentation has been extensively studied for more than a decade. In the 1940s the uniqueness of the spermatozoa protein complex which stabilizes the DNA was discovered. In the fifties and sixties, the association between unstable chromatin structure and subfertility was investigated. In the seventies, the impact of induced DNA damage was investigated. In the 1980s the concept of sperm DNA fragmentation as related to infertility was introduced as well as the first DNA fragmentation test: the Sperm Chromatin Structure Assay (SCSA)...

Ahmad Majzoub, Ashok Agarwal
INTRODUCTION: Idiopathic oligoasthenoteratozoospermia (iOAT) is commonly encountered during the evaluation of men with infertility. Antioxidants have been utilized empirically in the treatment of iOAT based on their ability to reverse oxidative stress (OS)-induced sperm dysfunction often encountered in this patient population. METHODS: A literature search was performed using MEDLINE/PubMed, focusing on publications of antioxidant therapies for iOAT. The main objective of our review article was to report the rationale and available evidence supporting the use of antioxidants...

REVIEW
Ashok Agarwal, Ahmad Majzoub
INTRODUCTION: Oxidative stress (OS) is considered a significant contributor to male infertility. A number of laboratory techniques have been developed to evaluate oxidative stress in the semen. We review these tests and their current use. METHODS: A literature review was performed utilizing the PubMed search engine for articles studying OS etiology and impact on male fertility, and the laboratory tests used in its assessment. RESULTS: The state of OS results from exaggerated production of oxygen-derived free radicals, also known as reactive oxygen species, to an extent overwhelming the body's antioxidant defense mechanisms...

INTRODUCTION: Infertility affects approximately 15% of all couples, and male factor contribute to up to 50% of cases. Unfortunately, the cause of male infertility is unknown in about 30% of these cases. Infertility of unknown origin is classified as idiopathic male infertility when abnormal semen parameters are present. Despite not having a definable cause, these men may respond to treatment. This review focuses on the use of empiric hormonal therapies for idiopathic male infertility...

BACKGROUND: Children, adolescents, and young adults (children/youth) with differences/disorders of sex development (DSD) face challenges related to future fertility; this may be due to variations in gonadal development, and, for some, gonadectomy performed to reduce the risk of malignancy. Childhood may be the only time for preservation of biological fertility potential for children/youth who undergo gonadectomy or have early gonadal failure. Fertility-related decision-making for these patients is particularly complicated, due to the need for parental proxy decision-making, potential discordance between gender identity and gonadal type, and uncertain future assisted reproductive technologies...

The pioneering of intracytoplasmic sperm injection (ICSI) approximately 25 years ago revolutionized the treatment of infertile couples. Today, ICSI remains an indispensable part of assisted reproductive treatments (ART) and has resulted in the birth of millions of babies. The 25th anniversary of ICSI marks a chronologic landmark in its evolving history. This landmark also serves as an opportunity to thoroughly appraise the safety of ICSI and analyze the long-term outcomes of ICSI-conceived children. In this review, we collate and analyze salient data accrued over the past 25 years pertaining to the long-term safety of ICSI and ICSI conceptions...

Endometriosis is an estrogen-dependent chronic inflammatory condition that affects women in their reproductive period causing infertility and pelvic pain. The disease, especially at the ovarian site has been shown to have a detrimental impact on ovarian physiology. Indeed, sonographic and histologic data tend to support the idea that ovarian follicles of endometriosis patients are decreased in number and more atretic. Moreover, the local intrafollicular environment of patients affected is characterized by alterations of the granulosa cell compartment including reduced P450 aromatase expression and increased intracellular reactive oxygen species generation...

Phytochemicals are non-nutrient bioactive compounds that occur in plant and food which possess the capacity to modulate one or more metabolic processes or pathways in the body, resulting to health benefits and promotion of well-being. At this regard, the interest of the scientific community continues to grow, powered by progressive research efforts to identify properties and potential applications of bioactive substances, and coupled with public interest and consumer demand. However, the natural derivation of these compounds is not a feature of harmlessness, over that of therapeutic efficacy, to which is also added the absence of post-marketing monitoring that does not allow to evaluate the occurrence of adverse effects related to the use of their related products...

The alarming trend in opiate misuse in developed countries is prompting an increasingly strident public call for action. Although many in our field have assumed that this building crisis does not really affect us or our patients, data show that the emerging demographic at highest risk for misusing opiates clearly includes patients who seek care in our practices. The goals of this Views and Reviews are to provide a clear understanding of emerging trends in opiate misuse, to review the impact of opiates on the reproductive axis, and to suggest practical recommendations aimed at both mitigating iatrogenic influences on promoting misuse and developing treatment frameworks when misuse is suspected or identified...

This review describes necrospermia, its diagnosis, causes and management. Sperm vitality is commonly assessed in the laboratory of reproductive biology, with the eosin test or with the hypo-osmotic swelling test. Necrospermia is defined by a percentage of living spermatozoa inferior to 58%, and can be related to male infertility. Several pathological mechanisms may be involved and can be classified either in testicular causes (hyperthyroidism, local hyperthermia, varicocele), or post-testicular causes (epididymal necrospermia, dysregulation of seminal plasma, adult polycystic kidney disease, vasectomy reversal, anti-sperm antibodies) or both (infection, toxic, age, spinal cord injury)...

Seasonal infertility is a significant problem in the swine industry, and may be influenced by photoperiod and heat stress. Heat stress during gestation in particular affects pregnancy, resulting in long-term developmental damage to the offspring. This review summarizes what is known about how heat stress on the pregnant sow affects lactation and her offspring. Sows responded to heat stress during gestation with increased rectal temperature, respiration rate, and skin temperature, and tended to reduce their activity-which may have changed their body composition, increasing the adipose-to-muscle ratio...

Hereditary hemochromatosis is a genetic disease that progresses silently. This disease is often diagnosed late when complications appear. Hypogonadotropic hypogonadism (HH) is one of the classical complications of hemochromatosis. Its frequency is declining probably because of earlier diagnosis and better informed physicians. Certain symptoms linked to HH can have an impact on a patient's sexuality, such as decreased libido, erectile dysfunction, and impairment of ejaculation, as well as on his reproductive capacities...

Infertility is the result of failure due to an organic disorder of the reproductive organs, especially their gametes. Recently, much progress has been made on generating germ cells, including oocytes, from various types of stem cells. This review focuses on advances in female germ cell differentiation from different kinds of stem cells, with emphasis on embryonic stem cells, adult stem cells, and induced pluripotent stem cells. The advantages and disadvantages of the derivation of female germ cells from several types of stem cells are also highlighted, as well as the ability of stem cells to generate mature and functional female gametes...
