TL;DR: Investigation of the associations between male age and sperm DNA damage and the influence of several lifestyle factors in a healthy non-clinical group of 80 non-smokers with no known fertility problems indicates that older men have increased sperm DNADamage associated with alkali-labile sites or single-strand DNA breaks and independent of age, men with substantial daily caffeine consumption have increased DNA damage associated with double-stranded DNA breaks.
Abstract: The trend for men to have children at older ages raises concerns that advancing age may increase the production of genetically defective sperm, increasing the risks of transmitting germ-line mutations. We investigated the associations between male age and sperm DNA damage and the influence of several lifestyle factors in a healthy non-clinical group of 80 non-smokers (age: 22-80) with no known fertility problems using the sperm Comet analyses. The average percent of DNA that migrated out of the sperm nucleus under alkaline electrophoresis increased with age (0.18% per year, p=0.006); but there was no age association for damage measured under neutral conditions (p=0.7). Men who consumed >3 cups coffee per day had {approx}20% higher % tail DNA under neutral but not alkaline conditions compared to men who consumed no caffeine (p=0.005). Our findings indicate that (a) older men have increased sperm DNA damage associated with alkali-labile sites or single-strand DNA breaks, and (b) independent of age, men with substantial daily caffeine consumption have increased sperm DNA damage associated with double-strand DNA breaks. DNA damage in sperm can be converted to chromosomal aberrations and gene mutations after fertilization increasing the risks for developmental defects and genetic diseases among offspring.

TL;DR: Investigation is warranted to explore the nature of the association between intimate partner violence and unintended pregnancy as well as the mechanisms through which these phenomena operate in the United States and in developing countries.
Abstract: Although a substantial body of literature explores the adverse physical and mental health consequences associated with intimate partner violence, only a limited body of international research has explored the effect of intimate partner violence on women's fertility control. Yet a compelling argument can be made of the indirect mechanism through which the climate of fear and control surrounding abusive relationships could limit women's ability to control their fertility. Lack of fertility control can lead to unintended pregnancies, which are also associated with adverse outcomes for women's and infant health, especially in developing countries. The association between intimate partner violence and unintended pregnancy also suggests serious social effects spawned by a cycle of unintended childbearing in abusive households. Therefore, further investigation is warranted to explore the nature of the association as well as the mechanisms through which these phenomena operate in the United States and in developing countries.

TL;DR: It is concluded that SCSA DFI adds to the value of semen analysis in prediction of the chance of natural conception.
Abstract: Standard sperm parameters have a limited power for prediction of the chance of natural conception. Recent studies have indicated that the sperm chromatin structure assay (SCSA) DNA fragmentation index (DFI), a measure for the fraction of sperms with DNA damage, is associated with fertility in vivo. The aim of this study was to evaluate the value of this parameter for prediction of infertility. One hundred and twenty-seven men from infertile couples with no known female factor and 137 men with proven fertility were included. Semen analysis was performed as recommended by the WHO. DFI was assessed using SCSA. Logistic binary regression was used to compute the odds ratios (OR) for infertility. As compared with men with a DFI 20% (OR 8.4; 95% CI: 3.0-23). In men with normal standard semen parameters (sperm concentration, motility and morphology) the OR for infertility was increased with DFI >20% (OR 5.1, 95% CI: 1.2-23), whereas if one of the standard semen parameters was abnormal, the OR for infertility was increased already at DFI above 10% (OR 16, 95% CI: 4.2-60). We conclude that SCSA DFI adds to the value of semen analysis in prediction of the chance of natural conception.

TL;DR: Options for fertility preservation remain limited but are improving rapidly, and providing advice on treating vaginal dryness and brief sexual counseling can often alleviate sexual dysfunction.
Abstract: Premature ovarian failure is a common consequence of systemic treatment for premenopausal breast cancer. Vasomotor symptoms and sexual dysfunction occur frequently in women who have an abrupt menopause from chemotherapy or ovarian suppression. However, current fertility may be impaired even in women who are menstruating after chemotherapy, and survivors are at high risk for permanent ovarian failure at a young age. Hot flashes can be managed with venlaxafine, gabapentin, or-potentially-stress management. Providing advice on treating vaginal dryness and brief sexual counseling can often alleviate sexual dysfunction. Options for fertility preservation remain limited but are improving rapidly. Distress about interrupted childbearing has a long-term impact on the quality of life.
