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.
