How do IVF patients interpret claims about fertility treatments? A randomised survey experiment

Trials evaluating the efficacy of IVF and various treatment options often focus on upstream outcome measures, improvements which may not translate into clinical outcome improvements. A cross-sectional online survey was distributed globally among IVF patients. Respondents were randomised to view one of 16 statements about a hypothetical IVF treatment option called 'FertiSure', stated to improve one of four upstream outcomes. Statements varied in whether they contained information stating that FertiSure was not proven to improve live-birth rates and about potential risks. Many patients inferred that improvements in upstream outcomes would result in improvements in the probability of live-birth. Nearly 80% of respondents were willing to use FertiSure. Respondents told that FertiSure was not proven to improve live-birth rates and were less willing to use FertiSure. More respondents agreed that FertiSure may pose a risk to patients when they were told this was the case. However, this did not affect their willingness to use FertiSure. Interestingly, 34% of respondents believed FertiSure would not improve the probability of live-birth but were still willing to use it. These results have implications for IVF clinic websites and information about treatment options which may not routinely contain statements about the limited evidence-base and possible risks.

Analysis of fertility clinic marketing of complementary therapy add-ons

Complementary therapies are often used during in-vitro fertilization (IVF) treatment. The aim of this study was to determine how UK fertility clinic websites are advertising complementary therapy add-ons. The Human Fertilisation and Embryology Authority's (HFEA) 'Choose a Fertility Clinic' website was used to identify fertility clinics and their websites. Acupuncture, reflexology, nutritional advice and miscellaneous complementary therapies were examined to determine treatment provision and costs. Treatment claims for acupuncture and reflexology were analysed using an inductive coding approach, and categorized depending on whether they pertained to holistic benefits, physiological benefits or improvements to IVF treatment outcome. At least one complementary therapy was advertised by 17 of 66 (26%) websites. Acupuncture was the most commonly advertised complementary therapy (16/66 clinic websites, 24%), followed by nutritionist services (11/66, 17%), reflexology (10/66, 15%) and other miscellaneous complementary therapies (9/66, 14%). Treatment costs were found to range from less than £50 for individual appointments to hundreds of pounds for treatment packages. Treatments were not always offered in-house at the fertility clinic, but rather patients were referred to an affiliated practitioner. Analysing claims relating to the complementary therapies highlighted that there were differences in the extent to which clinics claimed that complementary therapies benefited IVF, and that information occasionally acknowledged scientific research evidence but did not always present resources in an unbiased manner. Fertility clinic websites should provide accurate information for patients for complementary therapy add-ons. HFEA should add acupuncture and reflexology to their traffic-light system with amber and red ratings, respectively.

Live birth achieved despite the absence of ejaculated spermatozoa and mature oocytes retrieved: a case report

The most common reason for in vitro fertilization (IVF) cycle cancelation is a lack of quality gametes available for intracytoplasmic sperm injection (ICSI). Here we present the successful fertility treatment of the couple affected by obstructive azoospermia combined with suboptimal response to controlled ovarian stimulation. Since the conventional approach appeared ineffective to overcome both partnersˈ specific problems, the targeted interventions, namely, (1) pharmacological enhancement of sperm motility and (2) polarized light microscopy (PLM)-guided optimization of ICSI time, were applied to rescue the cycle with only immature oocytes and immotile testicular sperm retrieved. The treatment with theophylline aided the selection of viable spermatozoa derived from cryopreserved testicular tissue. When the traditional stimulation protocol failed to produce mature eggs, non-invasive spindle imaging was employed to adjust the sperm injection time to the maturational stage of oocytes extruding a polar body in vitro. The fertilization of 12 late-maturing oocytes yielded 5 zygotes, which all developed into blastocysts. One embryo was transferred into the uterus on day 5 post-fertilization, and another 3 good quality blastocysts were vitrified for later use. The pregnancy resulted in a full-term delivery of a healthy child. This case demonstrates that the individualization beyond the standard IVF protocols should be considered to maximize the chance of poor-prognosis patients to achieve pregnancy with their own gametes.
