Aim: Summarize the results of the many, but often underpowered, studies on pregnancy complicated by myoma or myomectomy. Methods: Survey of the electronic PubMed database for the last two decades was conducted. We selected reviews, meta-analyses, case series, case reports, clinical studies only with statistical analysis, and guidelines from scientific societies. Results: Delaying childbearing leads to an increased incidence of pregnancy complicated by fibroids or previous myomectomy. Approximately 10-30% of pregnant women with myomas develop complications during gestation, at delivery and in puerperium. Submucosal, retroplacental, large and multiple myomas have a greater risk of complications. Cervical myomas, although rare, need careful management. The location and size of the fibroids should be assessed from the first trimester. Despite the increased risk of cesarean section, fibroids are not a contraindication to labor, unless they obstruct the birth canal or other obstetric conditions coexist. Myomectomy during pregnancy, in selected cases, is feasible and safe. Myomectomy cannot be considered a prophylactic measure prior to conception, but has to be individualized. Uterine rupture after myomectomy generally occurs in the third trimester or during labor and some associated risk factors have been identified. There is no consensus on the optimal interval between myomectomy and conception. Conclusions: Pregnancy in patients with fibroids or previous myomectomy should be considered as high risk, requiring a maternal-fetal medicine specialist. To date available literature is inconsistent on evidence-based management. Further research is needed for definitive recommendations.

Bisphenol A (BPA) is a high production volume monomer used for making a wide variety of polycarbonate plastics and resins. A large body of evidence links BPA to endocrine disruption in laboratory animals, and a growing number of epidemiological studies support a link with health disorders in humans. The aim of this review is to summarize the recent experimental studies describing the effects and mechanisms of BPA on the female genital tract and to compare them to the current knowledge regarding the impact of BPA impact on female reproductive health. In particular, BPA has been correlated with alterations in hypothalamic-pituitary hormonal production, reduced oocyte quality due to perinatal and adulthood exposure, defective uterine receptivity and the pathogenesis of polycystic ovary syndrome. Researchers have reported conflicting results regarding the effect of BPA on premature puberty and endometriosis development. Experimental studies suggest that BPA’s mechanism of action is related to life stage and that its effect on the female reproductive system may involve agonism with estrogen nuclear receptors as well as other mechanisms (steroid biosynthesis inhibition). Notwithstanding uncertainties and knowledge gaps, the available evidence should be seen as a sufficient grounds to take precautionary actions against excess exposure to BPA.

Hundreds of thousands of young women are diagnosed with cancer each year, and due to recent advances in screening programs, diagnostic methods and treatment options, survival rates have significantly improved. Radiation therapy plays an important role in cancer treatment and in some cases it constitutes the first therapy proposed to the patient. However, ionizing radiations have a gonadotoxic action with long-term effects that include ovarian insufficiency, pubertal arrest and subsequent infertility. Cranial irradiation may lead to disruption of the hypothalamic-pituitary-gonadal axis, with consequent dysregulation of the normal hormonal secretion. The uterus might be damaged by radiotherapy, as well. In fact, exposure to radiation during childhood leads to altered uterine vascularization, decreased uterine volume and elasticity, myometrial fibrosis and necrosis, endometrial atrophy and insufficiency. As radiations have a relevant impact on reproductive potential, fertility preservation procedures should be carried out before and/or during anticancer treatments. Fertility preservation strategies have been employed for some years now and have recently been diversified thanks to advances in reproductive biology. Aim of this paper is to give an overview of the various effects of radiotherapy on female reproductive function and to describe the current fertility preservation options.

There is a widespread exposure of general population, including pregnant women and developing fetuses, to the endocrine disrupting chemicals (EDCs). These chemicals have been reported to be present in urine, blood serum, breast milk, and amniotic fluid. Endocrine disruptions induced by environmental toxicants have placed a heavy burden on society, since environmental exposures during critical periods of development can permanently reprogram normal physiological responses, thereby increasing susceptibility to disease later in life-a process known as developmental reprogramming. During development, organogenesis and tissue differentiation occur through a continuous series of tightly-regulated and precisely-timed molecular, biochemical, and cellular events. Humans may encounter EDCs daily and during all stages of life, from conception and fetal development through adulthood and senescence. Nevertheless, prenatal and early postnatal windows are the most critical for proper development, due to rapid changes in system growth. Although there are still gaps in our knowledge, currently available data support the urgent need for health and environmental policies aimed at protecting the public and, in particular, the developing fetus and women of reproductive age.

Cigarette smoking is associated with damaging effects on sperm parameters in infertile men and with ovarian reserve alteration in infertile women, as reflected by reduced AFC and increased FSH levels. Every smoker should be encouraged to stop smoking to prevent the damage of the toxins contained in cigarette smoking and preserve their own reproductive potential.
