Double time limit for embryo research say ethics experts

(Lancaster University) In countries which already permit embryo research, there are no 'compelling moral arguments' why the time limit for experimentation should not be doubled say ethics experts. This could enable synthetic embryos in the lab which can grow into humans, improved IVF treatment, the creation of 'organoid' models of human organs for replacement and research to allow infertile/same sex couples to have genetically related children.

Publication date: Available online 15 August 2018Source: Journal of Chemical NeuroanatomyAuthor(s): Cornelia Voigt, Nigel BennettAbstractThe eusocial Damaraland mole-rat (Fukomys damarensis) represents an extreme example of reproductive skew, in that reproduction is completely blocked in female subordinate group members. It is thought that in these animals normal GnRH secretion from the hypothalamus is disrupted. Prolactin, a peptide hormone secreted from the anterior pituitary gland, has been implicated in a wide variety of functions. Well documented in rodents is its role in mediating lactational infertility. Elevated ci...

Authors: Barut MU, Çoksüer H, Sak S, Bozkurt M, Ağaçayak E, Hamurcu U, Kurban D, Eserdağ S Abstract BACKGROUND Hypogonadotropic hypogonadism (HH), or secondary hypogonadism, results from reduced secretion of gonadotropins, including follicle-stimulating hormone (FSH) and luteinizing hormone (LH), by the pituitary gland, resulting in lack of production of sex steroids. The aim of this study was to evaluate self-reported sexual function in sexually active women with and without HH using two evaluation methods, the Female Sexual Function Index (FSFI) and the Beck Depression Inventory (BDI).

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...
