IntroductionSperm cryopreservation is increasingly recognized as a key strategy for fertility preservation, particularly for male infertility patients who may benefit from assisted reproductive technology (ART). However, the optimal abstinence period for maximizing semen quality prior to cryopreservation remains unclear, and whether this optimum varies with patient age has not been systematically…
Although assisted reproductive technologies have significantly advanced the treatment of infertility, overall success rates remain limited by the lack of accurate and safe tools for assessing reproductive potential. Conventional embryo selection and endometrial evaluation rely largely on morphological and non-functional criteria, which provide only indirect insight into the underlying biological …
Stored sperm may age faster than reproductive medicine has assumed, suggesting that shorter abstinence periods could benefit fertility outcomes. For decades, men undergoing fertility testing or treatment have often been advised to abstain from ejaculation for several days beforehand, based on the assumption that longer storage allows sperm counts to build up. But a major [...]
BackgroundThe total fertility rate (TFR) in most developed countries has been declining for decades. In the United States (U.S.), the total fertility rate has remained below replacement level since 2007. Subfertility affects at least 15% of women or couples over their reproductive lifespan and contributes to reduced TFR. Restorative reproductive medicine (RRM) is a medically based approach to sub…
GLP 1s do not harm male hormones or fertility after long-term use, according to a study being presented Monday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill. In fact, the research team found GLP-1s may improve testosterone levels and sperm quality in men with obesity related low testosterone, while also addressing the underlying effects of obesity.
PurposeTo determine whether intracytoplasmic sperm injection (ICSI) improves cumulative live birth rates (cLBR) compared with conventional IVF among patients with non–male factor infertility.MethodsThis descriptive retrospective cohort study used linked Canadian Assisted Reproductive Technologies Registry (CARTR Plus) and Better Outcomes Registry & Network (BORN) data from 2013 to 2022. Outcomes …
And carries a lower risk of complications for the mother Natural ovulation before frozen embryo transfer is as effective as hormone treatment for achieving a healthy baby by vitro fertilisation (IVF), finds a clinical trial from China published by The BMJ today. Natural ovulation is also linked to a lower risk of several complications for the mother, such ...
By understanding how our reproductive systems work, from sperm and egg development to conception, implantation and early embryo development, researchers and doctors have been able to develop family planning advice, contraceptive methods and fertility techniques for people struggling to conceive. But there is still much to learn, including uncovering the causes of unexplained infertility. Keep up …
What we know for certain so far, and what has been met with some fanfare, is that the province will provide funding for one cycle of IVF for every Ontarian who wants it, except for those over the age of 42. Specifically, the policy defines one cycle as one egg retrieval, which may yield multiple […]
