Adult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically...

Amongst infertile couples, 25% involve both male and female factors, while male factor alone accounts for another 25% due to oligo-, astheno-, terato-zoospermia, a combination of the three, or even a complete absence of sperm cells in the ejaculate and can lead to a poor prognosis even with the help of assisted reproductive technology (ART). Intracytoplasmic sperm injection (ICSI) has been with us now for a quarter of a century and in spite of the controversy generated since its inception, it remains in the forefront of the techniques utilized in ART...

As gonadotoxic adverse effects of antineoplastic treatments can result in infertility, gamete cryopreservation is routinely offered to patients as the strategy to preserve their fertility. However, there are many cases where gold standards cannot be applied, as is the case for prepubertal cancer patients and others unable to produce gametes or their precursors at the moment of diagnosis. With an increasing number of cancer survivors in our society, strategies using either cryopreserved gonadal tissue or stem cells have been developed to allow cancer survivors to achieve fatherhood, and recent advances in the field have increased public interest...

Proper physiological function of the ovaries is very important for the entire female reproductive system and overall health. Reactive oxygen species (ROS) are generated as by-products during ovarian physiological metabolism, and antioxidants are indicated as factors that can maintain the balance between ROS production and clearance. A disturbance in this balance can induce pathological consequences in oocyte maturation, ovulation, fertilization, implantation, and embryo development, which can ultimately influence pregnancy outcomes...

BACKGROUND: Uterine fibroids occur in up to 40% of women aged over 35 years. Some are asymptomatic, but up to 50% cause symptoms that warrant therapy. Symptoms include anaemia caused by heavy menstrual bleeding, pelvic pain, dysmenorrhoea, infertility and low quality of life. Surgery is the first choice of treatment. In recent years, medical therapies have been used before surgery to improve intraoperative and postoperative outcomes. However, such therapies tend to be expensive.Fibroid growth is stimulated by oestrogen...

BACKGROUND: Hyperglycemia can result from a loss of pancreatic beta-cells or a decline in their function leading to decreased insulin secretion or may arise from insulin resistance and variable degrees of inadequate insulin secretion resulting in diabetes and related comorbidities. To date several reviews have addressed the issue of diabetes-related male infertility but most have focused on how metabolic syndrome causes the decline in male fertility. However, a comprehensive overview as to how diabetes-induced hyperglycemia impairs male fertility is missing...

Recently, literature has emerged that offers contradictory findings of idiopathic forms of isolated teratozoospermia that may confuse clinicians. Some researchers argue that at 0-1% of normal forms of spermatozoa, morphology itself cannot be a prognostic indicator of fertility, either in the planning of natural pregnancy, or when used in assisted reproduction. In this connection, the possible causes of teratozoospermia and alternative therapies are being actively sought, in addition to known invasive and costly procedures...

Male infertility is associated with a wide range of pathological conditions affecting both the sexual and other body systems: endocrine, nervous, blood, and immune. Laser therapy is a form of modern physiotherapy that applies low-intensity laser radiation in various parts of the body. It is widely used in all areas of modern medicine due to its high efficiency, ease of use, the absence of contraindications and side effects. The authors reviewed the results of 171 studies investigating laser therapy, of which 93 were experimental (20 in Russian and 73 international publications), 4 clinical and experimental (all in Russian), 74 clinical (73 in Russian and 1in English)...

OBJECTIVE: Intrauterine adhesion (IUA) is a major health problem that causes infertility, menstrual irregularities, and recurrent pregnancy losses in women. Unfortunately, treatments for IUA are limited, and there are currently no effective strategies for preventing IUA recurrence. In this review, we introduced the role of Hippo signaling in the normal endometrium and IUA and described the mechanisms by which the Hippo pathway integrates with the Wnt and transforming growth factor-β (TGF-β) signaling pathways to form an intricate network governing the development of fibrosis...

Total colectomy with ileal pouch-anal anastomosis (IPAA) is considered the standard procedure for the surgical management of ulcerative colitis. Despite the widespread utility of the procedure, as many as 75% of patients who undergo IPAA, experience at least 1 complication. This review highlights difficult intraoperative scenarios and complications of pouch surgery in children, including intraoperative, postoperative, and functional complications. Intraoperative scenarios include insufficient mesenteric length and positive leak tests...

Gonadotropin-releasing hormone (GnRH) neurons are critical to many aspects of fertility regulation, from producing episodic release critical to both sexes, to providing a central signal to induce the ovulatory cascade in females. This year saw progress through the rejection, and occasional support, of hypotheses in understanding how GnRH neurons contribute to these processes. This brief review provides one laboratory's view of new insights into possible roles for these cells in development, adult reproductive function, and what may go wrong with GnRH neurons in some cases of infertility...

REVIEW
Ashok Agarwal, Albert Danh Bui
Male infertility affects men worldwide. Oxidative stress (OS), characterized by an overabundance of reactive oxygen species (ROS) or a deficiency of antioxidants, is one of the major causes of male infertility. OS causes damage at the molecular level, which impairs lipids, proteins, and DNA. The cyclic cascade of redox reactions weakens sperm function which leads to poor semen parameters and eventual sterility. There is a need for advanced diagnostic tests that can quickly and accurately detect OS. Most commonly used assays can only measure single constituents of OS...

There is substantial evidence that paternal obesity is associated not only with an increased incidence of infertility, but also with an increased risk of metabolic disturbance in adult offspring. Apparently, several mechanisms may contribute to the sperm quality alterations associated with paternal obesity, such as physiological/hormonal alterations, oxidative stress, and epigenetic alterations. Along these lines, modifications of hormonal profiles namely reduced androgen levels and elevated estrogen levels, were found associated with lower sperm concentration and seminal volume...

BACKGROUND: Human papillomavirus (HPV) is one of the most prevalent sexually transmitted viruses. Despite the increasing evidence of HPV prevalence in semen, the worldwide distribution of HPV types in semen and risk for male infertility remain inconclusive. METHODS: Four electronic databases were searched for English language studies conducted between January 1990 and December 2016 that reported HPV DNA prevalence in semen. Based on the PRISMA guidelines, HPV prevalence was estimated among general population and fertility clinic attendees, respectively, and heterogeneity testing was performed using Cochran's Q and I (2) statistics...

Adenomyosis is a benign condition characterized by the presence of endometrial glands and stroma deep within the myometrium. In recent years, the potential negative impact of adenomyosis on in vitro fertilization clinical outcomes has gained momentum, as well as, the possible link of this condition with obstetrical complications. The aim of this narrative review is to elucidate the possible association between uterine adenomyosis, infertility, and poor obstetrical outcomes. Several theories have been proposed to clarify the potential harmful impact of adenomyosis on fertility, such as a functional and structural defect of both the eutopic endometrium and the inner myometrium, an impairment of the uterine system of sperm transport, the presence of uterine dysperistalsis and of high levels of free radicals in the uterine milieu of women with the disease...

Context • Depending on the cause of the infertility, nonsurgical or surgical treatments may be used to treat men and women with infertility. Despite improved outcomes due to medical advances, assisted reproductive technology (ART) for couples with infertility is sometimes unsuccessful. Success may be affected by the patient's social, psychological, and physical status. Objective • The study examined the effects of yoga-including asanas (yoga poses), pranayama (proper breathing), shavasana, and meditation-on male and female fertility and ART outcomes...
