Alcohol consumption is widespread in the Western world. Some studies have suggested a negative association between alcohol intake and semen quality although others have not confirmed this. MEDLINE and Embase were searched using 'alcohol intake' OR 'alcohol consumption' OR 'alcohol drinking' OR 'lifestyle' combined with 'semen quality' OR 'sperm quality' OR 'sperm volume' OR 'sperm concentration' OR 'sperm motility' for full-length observational articles, published in English. Reference lists of retrieved articles were searched for other pertinent studies. Main outcome measures were sperm parameters, if provided as means (standard deviation or standard error) or as medians (interquartile range). Fifteen cross-sectional studies were included, with 16,395 men enrolled. Main results showed that alcohol intake has a detrimental effect on semen volume (pooled estimate for no/low alcohol consumption 0.25 ml, 95% CI, 0.07 to 0.42) and normal morphology (1.87%, 95% CI, 0.86 to 2.88%). The difference was more marked when comparing occasional versus daily consumers, rather than never versus occasional, suggesting a moderate consumption did not adversely affect semen parameters. Hence, studies evaluating the effect of changes on semen parameters on the reproductive outcomes are needed in advance of providing recommendations regarding alcohol intake other than the advice to avoid heavy alcohol drinking.
Fertility issues have become critical in the management and counseling of BRCA mutation carriers. In this setting four points deserve consideration. (1) Women in general lose their ability to conceive at a mean age of 41 years, thus the suggested policy of prophylactic bilateral salpingo-oophorectomy at age 40 for BRCA mutation carriers does not affect the chances of natural pregnancy. Conversely, if the procedure is chosen at 35 years old, oocyte cryopreservation prior to surgery should be considered. (2) Some evidence suggests that ovarian reserve may actually be partly reduced in BRCA mutations carriers and that the mutation may affect ovarian responsiveness to stimulation. However, these findings are still controversial. (3) Breast cancer is not rare before the age of 40 and fertility preservation after diagnosis can be requested in a significant proportion of BRCA mutation carriers. Thus, a policy of oocyte cryopreservation in young healthy carriers deserves consideration. The procedure could be considered at a young age and in an elective setting, when ovarian stimulation may yield more oocytes of better quality. (4) Preimplantation genetic diagnosis (PGD) could be considered in BRCA mutations carriers, particularly when good quality oocytes have been stored at a young age. Based on the current knowledge, a univocal approach cannot be recommended; in depth patient counseling is warranted.
Background: Several diet patterns have been suggested as involved in processes of spermatogenesis and thus in male subfertility. To study the relation between Mediterranean diet and abnormal sperm parameters in men of subfertile couples, we performed a cross-sectional analysis of baseline data from a prospective cohort study. Methods: Patients were enrolled in an Italian Fertility Clinic. Couples undergoing assisted reproduction techniques (ART) were interviewed to obtain information on personal and health history, lifestyle habits, and diet, on the day of oocyte retrieval. On the same day, a semen sample was also collected and analyzed to proceed with ART. Adherence to Mediterranean diet was evaluated using a Mediterranean Diet Score (MDS). Odds ratios (OR) and 95% confidence intervals (CI) were calculated for semen volume <1.5 mL, sperm concentration <15 mil/mL, and total count <39 mil. Results: Three hundred nine men, age range 27-60, were enrolled: 19.3% had semen volume < 1.5 mL, 30.5% sperm concentration <15 mil/mL, and 32.1% total count <39 mil. MDS was low (0-3) in 86 men (27.8%), intermediate (4)(5) in 131 (42.4%), and high (6-9) in 92 (29.8%). Semen volume was not associated with MDS. Compared to the highest MDS category (6-9), the ORs for low sperm concentration were 1.34 (95% CI 0.69-2.50) for MDS 4-5 and 2.42 (95% CI 1.21-4.83) for MDS 0-3, with significant trend (p = 0.011). The corresponding estimates for total count were 1.26 (95% CI 0.66-2.42) and 2.08 (95% CI 1.05-4.12), with significant trend (p = 0.034). These findings were consistent in strata of history of reproductive organ diseases. Conclusions: Mediterranean Diet Score was positively associated with normal sperm concentration and total count, but not with semen volume.
This analysis shows that EA CCs and E ovarian cases are diagnosed at an earlier stage than cases without endometriosis. No clear association emerged between presence of endometriosis and survival.
Tamoxifen is frequently used as adjuvant treatment in premenopausal patients with hormone receptor-positive early breast cancer. According to guidelines, the use of nonhormonal barrier contraception is recommended during tamoxifen treatment and up to 3 months after its interruption prior to attempting conception. Nevertheless, when conception occurs inadvertently during tamoxifen treatment, the effects on the fetus and on the course of pregnancy are still not completely known. Here, we report 3 cases of young women who accidentally became pregnant while taking tamoxifen and perform a systematic review of the literature to provide more elements for better and clear multidisciplinary counselling of women facing this challenging situation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
