Obesity adversely affects the reproductive health of a woman as it is known to cause anovulation, menstrual irregularities, and infertility. However, the findings of various studies on the influence of BMI on controlled ovarian hyperstimulation factors, such as quantity of gonadotropin and days of stimulation required, oocyte quality/quantity, maximum level of estradiol, and success of pregnancy, are inconsistent. A recent prospective study reports that women with elevated BMI produce more follicles, and require fewer days of stimulation and gonadotropin during IVF treatment, although no significant effects on pregnancy outcome rates were reported.

Conventional sperm recovery procedures are hypothesized to depend on the migration of motile sperms away from washed epithelial cells and immotile sperms, thus leading to the elimination of infected epithelial cells and enabling virus-free sperm preparations. Although this seems biologically plausible, a recent cross-sectional clinical study highlights that conventional sperm selection techniques may not entirely remove the risk of HPV infection.

The lack of clear consensus on the definition of poor ovarian response (POR) in ART has made it difficult to compare results of various studies conducted to improve ovarian response; in turn hindering the identification of poor responders and selection of an optimal ovarian stimulation strategy. In a first realistic endeavor, the European Society of Human Reproduction and Embryology (ESHRE) working group proposed a standardized, simple, and reproducible definition for POR. The ESHRE consensus is published in the recent issue of the journal, Human Reproduction. Continue Reading

The increase in the success rates of ART over the past few decades has been mainly attributed to improved laboratory conditions and ovarian stimulation optimization, with less attention directed towards strategies for enhancing final oocyte maturation. A recent study, touted to be the first randomized double blind placebo-controlled clinical trial to alter the ovulation trigger to enhance the developmental competence of oocytes in IVF cycles, has reported a statistically significant improvement in fertilization after a follicle stimulating hormone (FSH) bolus administration at the time of human chorionic gonadotropin (hCG) trigger, compared to placebo, in IVF cycles.

A new retrospective case-control study has reported that oocyte retrieval via transabdominal ultrasound-guided follicular aspiration is safe and effective in IVF patients with substantial ovarian displacement, i.e. in cases where ovaries are inaccessible transvaginally. The study reported that the results were comparable to cycles where the oocytes were obtained by transvaginal aspiration in women with normally located ovaries. Continue Reading

Low chromatin packaging quality in morphologically normal spermatozoa is one of the important factors that lower the fertilization capability of the sperm. Therefore, evaluating DNA integrity is essential to determine actual sperm fertility potential. A recent prospective study published in Fertility and Sterility provides new evidence that DNA integrity analysis using alkaline comet assay may be beneficial in diagnosing male infertility and predicting IVF outcomes.

The results of a recent randomized, prospective, controlled study published in the journal, Human Reproduction, adds credence to the potential of dehydroepiandrosterone (DHEA) supplementation in enhancing IVF treatment outcomes in poor responders. Continue Reading

Several studies have established the effect of obesity (BMI >30 kg/m2) on female fertility as well as on ART treatment outcomes; however, the mechanism underlying the association is still obscure. Now, a recent study published in the journal Reproduction, sheds more light on the impact of obesity on the major reproductive mechanisms and infertility treatment. Continue Reading

Recent guidelines issued by the British Fertility Society (BFS) report a lack of sufficient evidence to substantiate the use of alternative medicines, Chinese herbal medicine and acupuncture, in conjunction with ART, to improve the chances of successful pregnancy or live birth rates. The recommendations were based on the systemic review and meta-analysis findings published in the journal, Human Fertility. Continue Reading

Lifestyle modification to tackle obesity, tobacco smoking and alcohol consumption, have been proposed as crucial in influencing the outcome of both natural and assisted conceptions. A recent statement released by the European Society of Human Reproduction and Embryology (ESHRE) further substantiates this association. Continue Reading
