The Center for Reproductive Research aims to improve understanding of hormones, receptors, and signaling molecules in female reproduction. Researchers will develop synthetic scaffolds and investigate molecular machines to address diseases associated with reproductive function.
A study reveals that EXO1 is essential for both male and female germ cell meiosis, highlighting its role in fertility. Mice lacking Exo1 function developed tumors and experienced severely depleted sperm levels, suggesting a link between EXO1 and cancer.
A new study found that teenage girls with polycystic ovary syndrome (PCOS) are significantly more worried about their future fertility compared to healthy age-mates. The study also revealed that PCOS patients have lower scores in quality of life questionnaire categories, particularly self-esteem and mental health.
In a new study, researchers describe a less invasive fertility procedure that uses intraperitoneal insemination to treat infertile women with no cervical blockages. The technique bypasses the cervix by injecting sperm directly into the pelvic cavity, avoiding the need for more complex treatments.
A preliminary study found that the peritoneal fluid of women with early-stage endometriosis reduces ciliary beat frequency by around a quarter compared to fertile controls. This reduction may be linked to impaired ciliary action and tubal transport, which could negatively impact fertility.
Researchers developed a non-invasive method to generate a genetic fingerprint of fertile men's sperm cells, identified around 3000 individual mRNAs, and suggest it could help diagnose idiopathic infertility and reveal paternal influences on fetal development.
Researchers at Duke University Medical Center discovered a gene linked to male infertility in mice, which may also be associated with human infertility. The study found that the miwi gene plays an essential role in sperm production and its deficiency can lead to complete sterility in mice.
Researchers at USC found a significant correlation between decreased sperm count and motility and increased ozone levels in the air, especially in Southern California. The study analyzed over 8,000 sperm samples from men in Los Angeles and Northern California and suggests that air pollution may be affecting male fertility.
A study suggests that metformin, an oral diabetes drug, reduces the risk of miscarriage in women with Polycystic Ovary Syndrome (PCOS). Researchers found that 8.8% of pregnancies treated with metformin ended in miscarriage, compared to 41.9% in those not receiving the medication.
A new study from the Mayo Clinic has identified a crucial protein involved in male fertility, shedding light on a common cause of infertility. The research found that mice lacking this protein are infertile, highlighting the importance of Hrb protein in acrosome development.
A new study proposes revised guidelines for classifying semen samples as normal or abnormal, potentially rewriting laboratory standards used for 50 years. The research suggests that male infertility is not as clear-cut as current guidelines suggest, and that a 'gray zone' of borderline semen samples requires new treatment approaches.
Researchers found AAV DNA in 38% of men with abnormal semen analysis, but only 4.6% of those with normal semen. Further studies are needed to assess the link between AAV and infertility.
A new study reveals that exposure to pesticides and solvents in men is associated with lower sperm threshold values and changes in hormone concentrations, particularly affecting primary infertility. The research highlights the potential impact of environmental factors on male reproductive health.
Researchers have discovered a potential cause of male infertility, identifying the ZNF214 gene as a candidate gene. The gene is linked to impaired spermatogenesis and may be inherited from mothers. Further research will help understand its role in sperm production and develop targeted treatments.
Researchers have developed a new fertility test kit that measures natural levels of fertility in couples trying to conceive. The kit assesses the concentration of motile sperm in men and follicle-stimulating hormone (FSH) levels in women, providing an early warning system for potential infertility issues.
Researchers have developed a new test, SUTI, that can accurately diagnose male infertility by detecting high levels of ubiquitin antibodies on the surface of sperm cells. This method could lead to more accurate diagnoses and targeted treatment for couples struggling with infertility.
The targeted disruption of the PCI gene in mice leads to profound defects in sperm development and fertility. Human male infertility is also associated with a lack of PCI in seminal fluid, disrupting the balance of proteinases and proteinase inhibitors.
A new study suggests that proteins alphav-beta3 and leukemia inhibitory factor (LIF) may serve as biomarkers for identifying women with endometriosis-related infertility. The research found a marked reduction in embryo implantation in mice injected with peritoneal fluid from infertile women with endometriosis.
A Dutch gynaecologist warns couples about the risks of Assisted Reproductive Technology (ART) and advises them to consider natural conception first. Nearly half of women who have not conceived after a year will conceive naturally, making informed decisions crucial before treatment.
For couples experiencing unexplained infertility, a five-step treatment program has shown a 75% success rate in conception. The program includes careful evaluation and escalating steps such as antibiotics, intra-uterine insemination, and IVF with ICSI.
Couples undergoing infertility treatment experience intense emotional highs and lows, with physical discomfort being a secondary issue. The promise of technology to control reproduction only exacerbates the problem, leading to increased distress for those who fail to conceive.
A study by UCSF researchers found evidence of faulty DNA repair in some infertile men, similar to those with certain cancers. The study suggests that defective DNA repair may be a reason for male infertility and potentially increase the risk of offspring infertility and cancer.
Research suggests that home screening kits for Chlamydia, a common sexually transmitted infection, could be a useful tool in preventing lifelong infertility. The study found that men and women aged 18-35 were willing to participate in urine test kits, with higher participation rates among those from Avon than London.
A team led by David Page has discovered the first mutation on the Y chromosome linked to male infertility. The finding may lead to the development of treatments and male contraceptives.
Researchers found that treating women to ovulate and inseminating them through the uterus resulted in more pregnancies than other methods. The combination of superovulation and intrauterine insemination was deemed effective for infertile couples with no identifiable infertility factor and motile sperm.
Researchers link biblical story of Hannah to first documented case of anorexia nervosa and its associated infertility. The article, published in Fertility and Sterility, suggests that extreme weight loss may have contributed to Hannah's inability to conceive.
Women with polycystic ovary syndrome (PCOS) may experience menstrual irregularities, infertility, and increased body hair due to hormonal imbalances. Research suggests that PCOS may be inherited, affecting both males and females in the family.
A two-year study on wild baboons found that environmental factors such as social status and seasonal conditions significantly impact reproduction. The research suggests that understanding these natural processes can inform the development of new treatments for human infertility.
