New sperm creation method could overcome genetic male infertility – study

Healthy sperm have been created in mice with a common form of infertility, raising hope for future treatment for men with extra sex chromosomesA common genetic cause of male infertility has been overcome in mice using a technique that creates healthy sperm in the laboratory, scientists have shown.The research raises the future prospect of hope for men who cannot father children because they have three instead of two sex chromosomes.Continue reading...

Dear science, Today my sons, Oliver and Victor, are 15 years old. It is not a miracle; it is thanks to you. Unable to get pregnant I needed infertility therapy. If you had not isolated the hormones, developed tests, and then designed medications for ovarian stimulation and to trigger ovulation I would never have become pregnant. If ultrasound had not been developed I would not have known I was pregnant with triplets and then what eventually happened next would likely have been even more of a catastrophe. It is sometimes hard to see how these kinds of things helped, but I have not forgotten. I know there is an orchestra inv...

AbstractAlthough assisted reproduction techniques involve the use of semen samples, there is little scientific methodology applied when selecting sperm. To select the most appropriate spermatozoa, first we need to define the optimal molecular characteristics. Sperm lipids may contribute to sperm function, thus our aim was to compare the lipidic profiles of sperm samples used in intracytoplasmic sperm injection cycles that ultimately led to a pregnancy with those that did not.Spermatozoa from infertile patients after intracytoplasmic sperm injection (group non-pregnant,n = 16; vs. group pregnant,n =&thi...

The separation of motile sperm from semen samples is sought after for medical infertility treatments. In this work, we demonstrate a high-throughput microfluidic device that can passively isolate motile sperm within corrals inside a fluid channel, separating them from the rest of the diluted sample. Using finite element method simulations...

Conclusions: All breakpoints at chromosome 2 were correlated with gestational infertility. Carriers of chromosome 2 translocations should therefore receive counseling to continue with natural conception and use of different technologies available via assisted reproductive technology, such as preimplantation genetic diagnosis.

ABSTRACT Prostatic utricle cyst is a rare congenital anomaly. Symptomatic cysts require treatment. Surgical excision is the treatment of choice, but is challenging due to close proximity to vas deferens, ejaculatory ducts, bladder, prostate, rectum and pelvic nerves. Complications include rectal injury, ureteral injury, impotence, infertility and faecal incontinence. We here report a rare complication in which bladder was accidentally removed during laparoscopic excision of prostatic utricle cyst. To best of our knowledge such a complication has never been reported previously. We also describe the possible cause of this ac...
