NEWS: Radiofrequency electromagnetic waves of laptops with Wi-Fi may decrease male fertility

A recent prospective in vitro study, claimed to be the first to assess the impact of laptops with wireless local area network connection (Wi-Fi) on spermatozoa, reports that prolonged use by keeping the device on the lap may reduce male fertility.

NEWS: New cryoprotectant-free, permeable capillary technique to help standardize sperm vitrification

A team of researchers has developed a new technology for cryoprotectant-free, sperm vitrification, using capillaries that have standard cylindrical shape and fixed diameter. The promising technique will help to standardize the vitrification procedure with precise, quantifiable volumes of spermatozoa.

Antisperm Antibodies May Not Adversely Influence ART Pregnancy Rates

Antisperm Antibodies May Not Adversely Influence ART Pregnancy Rates

Literature searches on the link between direct semen antisperm antibody (ASA) levels and treatment outcomes in ART cycles have not yielded clear results. Now, a systemic review suggests that semen ASA is not associated with pregnancy rates after IVF or ICSI cycles, thereby indicating the effectiveness of such ART strategies in infertile couples with raised [...]

NEWS: Brief co-incubation insemination protocol may enhance IVF outcomes

15 May 2013

The standard overnight co-incubation of spermatozoa and oocytes has been compared with the brief co-incubation insemination protocol by numerous investigators in the past. However, it remains unclear whether reduction in the sperm-oocyte co-incubation time improves or negatively affects the outcomes of in vitro fertilization (IVF) therapy. According to a recent Cochrane review, the brief gamete [...]

NEWS: Polar body fragmentation in IVM oocytes negatively affects fertilization and embryo development

06 May 2013

Opinions vary on the importance of polar body morphology in predicting fertilization and embryo development. Most contemporary publications propose that fragmented polar body is not prognostic for oocyte fertilization or embryo development. However, a recent study demonstrates that the fertilization probability of an oocyte with fragmented polar bodies is far less compared to an oocyte [...]

NEWS: Corifollitropin alfa followed by highly purified HMG in a GnRH antagonist protocol may enhance IVF outcomes in poor ovarian responders

26 April 2013

The prognosis of successful IVF outcomes in women with low ovarian response fulfilling the Bologna criteria is very poor. A recent retrospective pilot trial reports that corifollitropin alfa followed by highly purified human menopausal gonadotrophin (hp-HMG) in a GnRH antagonist protocol results in promising pregnancy rates in poor ovarian responders fulfilling the Bologna criteria. However, [...]

NEWS: Presence of microorganisms in follicular fluid may negatively influence IVF outcomes

23 April 2013

Microbial colonization of the female upper genital tract even in the absence of symptomatic infection has been well documented in previous trials. A recent study demonstrates that the presence of microbes in the follicular fluid collected at the time of transvaginal oocyte retrieval adversely affects the outcomes of in vitro fertilization (IVF) therapy.

NEWS: Oral contraceptives with high androgenic progestins reported to suppress oocyte yields

15 April 2013

A recent retrospective study demonstrates that use of oral contraceptives with high androgenic progestin suppresses functional ovarian reserve and oocyte yields in young oocyte donors. Accordingly, researchers highlight the need for reevaluating the routine practice of using oral contraceptives prior to in vitro fertilization (IVF) cycles.

NEWS: Selection of hyaluronan bound sperm may enhance ICSI outcomes

02 April 2013

Sperm selection based on visual assessment alone has been speculated to be insufficient to identify sperm DNA integrity, which may play a major role in determining the outcome of intracytoplasmic sperm injection (ICSI) cycles. A recent, prospective, stratified, double-blinded, randomized controlled trial reports the benefits of utilizing the hyaluronan binding phenomenon for sperm selection in [...]

NEWS: Preliminary evidence indicates high anti-PLAC1 antibody level may serve as a biomarker of repeated IVF implantation failure

26 March 2013

Previous studies indicate that autoimmune antibodies may have an impact on implantation failure in in vitro fertilization-embryo transfer (IVF-ET) cycles. A recent observational, case-controlled clinical trial highlights that high circulating anti-placenta-specific 1 (PLAC1) antibody levels could be associated with an increased likelihood of repeated IVF-ET implantation failure.

NEWS: Lycopene improves altered polyunsaturated fatty acid levels in seminal plasma of infertile males

21 March 2013

An imbalance in the ratio of the polyunsaturated fatty acids (PUFAs), arachidonic acid and docosahexaenoic acid (AA/DHA) has been implicated in male infertility. A recent study highlights that treatment with lycopene significantly improves the AA/DHA ratio in the seminal plasma of infertile males and facilitates spontaneous as well as assisted conception among infertile couples. The [...]

NEWS: Expression of fibroblast growth factor-1 may likely influence implantation

04 March 2013

Recurrent implantation failure post in vitro fertilization (IVF) therapy has been attributed to numerous maternal and embryonic factors. A recent study, published in the European Review for Medical and Pharmacological Sciences, indicates that fibroblast growth factor-1 (FGF-1) may play a crucial role as a maternal factor influencing implantation.

NEWS: Nomogram based on age, antral follicle count, and day-3 FSH level may facilitate individualization of daily FSH starting dose

01 March 2013

A recent study highlights that a nomogram based on age, antral follicle count (AFC), and serum day-3 follicle stimulating hormone (FSH) levels may enable individualization of daily FSH starting dose in women undergoing in vitro fertilization (IVF) therapy. The researchers report that AFC and serum day-3 FSH are the most significant predictors of ovarian reserve [...]
