PURPOSE: Adolescent and young adult (AYA) cancer survivors experience fertility and childrearing challenges in adulthood, but there is limited evidence on awareness, beliefs, and concerns about oncofertility in this population, needs for supportive resources, and associations with quality of life (QoL). METHODS: Participants were 69 AYAs aged 12-25 who were diagnosed with cancer at age 18 years or younger and ≥1 year cancer free, recruited from childhood cancer clinical records and support organizations...

Polycystic ovary syndrome is a multifactorial endocrine disorder whose pathophysiology baffles many researchers till today. This syndrome is typically characterized by anovulatory cycles and infertility, altered gonadotropin levels, obesity, and bulky multifollicular ovaries on ultrasound. Hyperandrogenism and insulin resistance are hallmark features of its complex pathophysiology. Hyperandrogenemia is a salient feature of PCOS and a major contributor to cosmetic anomalies including hirsutism, acne, and male pattern alopecia in affected women...

Testicular cancer has become the paradigm of adult-onset cancer survivorship, due to the young age at diagnosis and 10-year relative survival of 95%. This clinical review presents the current status of various treatment-related complications experienced by long-term testicular cancer survivors (TCS) free of disease for 5 or more years after primary treatment. Cardiovascular disease and second malignant neoplasms represent the most common potentially life-threatening late effects. Other long-term adverse outcomes include neuro- and ototoxicity, pulmonary complications, nephrotoxicity, hypogonadism, infertility, and avascular necrosis...

STUDY QUESTION: Is maternal polycystic ovarian syndrome (PCOS) associated with developmental delays in offspring? SUMMARY ANSWER: Offspring of mothers with PCOS were at higher risk of failure on the Ages and Stages Questionnaire (ASQ). WHAT IS KNOWN ALREADY: There is growing evidence that offspring of mothers with PCOS may be at higher risk for developmental disorders due to potential exposure to hyperandrogenism and insulin resistance. Few studies exist regarding maternal PCOS and early childhood development in the USA...

Infertility is the inability to conceive after having regular unprotected sexual intercourse for more than 12 months and it can be caused by reproductive problems of men, women, or both, but sometimes the cause of infertility is unknown. At least 30 million men around the world suffer from infertility, most of whom are in Africa and Eastern Europe. Since infertility problems can have devastating emotional effects on couples as well as negative effects on the society, treatment of infertility is very important, as a result of which many studies have been carried out in this field and many treatments have been proposed...

OBJECTIVES: Chlamydial infection is often asymptomatic. The lack of symptoms may result in the infection developing into a chronic. Chlamydial infections of the genitourinary system in women can lead to serious complications like PID, fallopian tubes infertility, ectopic pregnancy, and chronic pelvic pain. An infection of the genitourinary system does not cause any lasting immune resistance and does not protect against re-infection. The aim of this research was to conduct tests for Chlamydia trachomatis on healthy women without any genital system symptoms and to estimate the frequency of asymptomatic infections...

PURPOSE: Uterine activity plays a key role in reproduction, and altered patterns of uterine contractility have been associated with important physiopathological conditions, such as subfertility, dysmenorrhea, and endometriosis. However, there is currently no method to objectively quantify uterine contractility outside pregnancy without interfering with the spontaneous contraction pattern. Transabdominal electrohysterography has great potential as a clinical tool to characterize noninvasively uterine activity, but results of this technique in nonpregnant women are poorly documented...

Male athletes in general are subjected to the same causes of infertility as the general population, but sports practice itself may be possibly an additional infertility factor or, at least an aggravating factor for a previously existing fertility condition; on the contrary, being physically active has been hypothesized to favor hormonal and seminological processes and could be beneficial for fertility. In this relationship, the different inherent parameters of physical activity-exercise (training volume, intensity, objective, organization and frequency) are of paramount importance...

PURPOSE OF REVIEW: The purpose of the current review is to describe the common pitfalls in design and statistical analysis of reproductive medicine studies. It serves to guide both authors and reviewers toward reducing the incidence of spurious statistical results and erroneous conclusions. RECENT FINDINGS: The large amount of data gathered in IVF cycles leads to problems with multiplicity, multicollinearity, and over fitting of regression models. Furthermore, the use of the word 'trend' to describe nonsignificant results has increased in recent years...

The reproductive realm is routinely viewed as a feminised space requiring women's commitment and labour. By contrast, men's procreative contributions and 'reproductive masculinity' is represented as unproblematic, with men assumed to be fertile across the lifespan. Recent scientific research has, however, cast doubt over these longstanding assumptions, suggesting that a link does exist between 'lifestyle' factors and male fertility. The notion that fertility can be improved with effort (for both women and men) can be located within wider cultural and political shifts which construct individuals as increasingly responsible for acting on health messages and engaging in self-disciplining body projects...

In vitro production of functional spermatids has special significance in the research of spermatogenesis and the treatment of male infertility. Primordial germ cells (PGCs) are the precursors of oocyte and sperm, which generate the totipotent cells. Studies have shown that PGCs have the potential ability to develop meiotic spermatids in vitro. Here we have shown that retinoic acid (RA) leads to PGC differentiation, and SCF can improve the efficiency of induction. We indicate an efficient approach to produce haploid spermatids from chicken PGCs in the presence of RA and stem cell factor (SCF)...

Endometriosis (EM) is a major cause of infertility and has a complex pathogenesis, which brings severe challenges in both clinical treatment and scientific research. Current clinical research focuses on the difficult problem of improving the pregnancy rate of EM patients. Our studies found that Chinese medicine has significant advantages in terms of improving the pregnancy rate of EM patients.

Infertility affects 15-20% of the reproductive age range population; the male factor accounts for up to 40-60% of these. With female factor infertility catching most of the limelight in research, diagnosis and treatment, the other half of the problem has not been duly addressed. Imaging has an important role to play in the evaluation of male infertility, especially to identify correctible (obstructive) causes. We review the scrotal, trans-rectal sonographic and Doppler findings in infertile men to aid in the accurate diagnosis and proper management of such patients...

Perceptions of fertility are thought to impact reproductive behaviors, yet little is known about how lay people conceptualize the female fertility timeline. In this research, public perception of the female fertility timeline was assessed via a national survey of U.S. adults (N = 990) ranging in age from 18 to 89 years. Although there is no scientific consensus on the makeup of the female fertility timeline, results from this research indicate that the U.S. public posits fertility onset at (approximately) 13 years, peak fertility at 22, ideal first pregnancy age at 23, too late for pregnancy at 46, and infertility at 49...

STUDY QUESTION: Can a discriminant threshold be determined for human sperm DNA oxidation? SUMMARY ANSWER: A discriminant threshold was found with 65.8% of 8-hydroxy-2'-deoxyguanosine (8-OHdG)-positive sperm cells and a mean intensity of fluorescence (MIF) of 552 arbitrary units. WHAT IS KNOWN ALREADY: Oxidative stress is known to interfere with sperm quality and fertilizing capacity. However, current practice does not include the routine determination of oxidative DNA damage in spermatozoa; optimized consensus protocols are lacking and no thresholds of normality have been established...

PCOS has a leading place in women's infertility. Based on the data of recent researches, Anti-Mullerian hormone (AMH) has been considered as one of the diagnostic criteria for PCOS. The aim of study was to determine the correlation of Anti-Mullerian hormone with hormonal and ovarian morphological characteristics in patients with PCOS, with and without insulin resistance. 110 women with diagnosis of PCOS were involved in the study. Patients were divided into two groups: PCOS patients with insulin resistance (60 women) and PCOS patients without insulin resistance (50 women)...
