What are Strongyloides?
Strongyloides is an opportunistic pathogenic parasitic nematode. Adults parasitize in the small intestine of cats, dogs and humans. The larvae can invade lung, brain, liver, kidney and other tissues and organs, causing strongyloidiasis. The disease is mainly prevalent in warm and humid tropical and subtropical regions. In recent years, due to the continuous increase of HIV/AIDS infection rate in ...

How CBD benefits you with worst period problems
Rumor has it that even Queen Victoria sought CBD benefits for relief from menstrual cramps. And it’s no wonder, doctors have described period cramps as “painful as a heart attack” or “cutting your finger off without anesthesia.” Prostaglandins are the main reason why period cramps hurt. The body releases this hormone into the lining of the uterus to make the ...

Home testing for timing of natural frozen embryo transfer (nFET) procedures; a solution for reducing clinic visits during Covid-19
This study sought to determine whether timing of nFET using home ovulation tests (OT) is a viable alternative to multiple clinic visits. Background Natural Frozen Embryo Transfer (nFET) is an increasingly popular procedure as it avoids early embryonic exposure to an artificially created hormonal environment which may be detrimental to pregnancy outcomes.1,2 nFET requires tracking of hormonal ...

hCG and FSH Levels During Early Pregnancy and Reproductive Aging
Low levels of hCG are known to be co-produced with FSH during reproductive aging (during peri-menopause and menopause). A missed period could be indicative of pregnancy or peri-menopause for woman in later reproductive life, so understanding the reference ranges for hCG is important. Introduction hCG assays have high sensitivity and specificity for pregnancy1 Low levels of hCG are known to ...

Timing of urinary estrone-3-glucuronide tests
Background The onset of a woman's fertile phase can be identified by an increase in concentration of urinary metabolites of estradiol, including E1-3G (estrone-3-glucuronide). Home ovulation tests typically detect the lutenising hormone (LH) surge, which identifies the day before and day of ovulation. Some tests also measure E1-3G to identify the user's wider fertile phase. Such tests ...

IVF Cryopreservation and Safe Handling Practices
Couples that want to have a baby but have not been able to conceive naturally are drawn to invitro fertilization (IVF) treatments. In an IVF treatment, several eggs are fertilized at once, which creates multiple embryos. While more than one embryo may be implanted, to spur the odds of pregnancy, there are inevitably some unused embryos. The remaining embryos may be preserved cryogenically, for ...

Chronic exposure to mono‐(2‐ethylhexyl)‐phthalate causes endocrine disruption and reproductive dysfunction in zebrafish
Phthalic acid esters are frequently detected in aquatic environment. In this study, zebrafish were exposed to low concentrations (0, 0.46, 4.0, and 37.5 µg/L) of mono‐(2‐ethylhexyl) phthalate (MEHP) for 81 days, and the effects on reproduction, gamete quality, plasma vitellogenin (VTG), sex steroids, and transcriptional profiles of key genes involved in steroidogenesis were investigated. The ...

Bisphenol A reduces fertilizing ability and motility by compromising mitochondrial function of sperm
Bisphenol A acts as an endocrine disruptor, affects animal reproductive success in vivo, and affects sperm functions in vitro at environmentally relevant concentrations leading to reduction in sperm motility and fertilizing ability in fish. The effect of in vitro BPA on avian sperm functions has not been explored. We tested the effect of environmentally relevant concentrations of BPA (0, 0.18, ...

Imposex and novel mechanisms of reproductive failure induced by tributyltin (TBT) in the freshwater snail Pomacea canaliculata
The effects of TBT on mortality and reproduction were studied in this invasive snail. The nominal fifty percent lethal concentration (LC50) was 9 µg TBT/L, after 28 days. The nominal ‘no observed effect on lethality concentration’ (NOECL) was 6 µg TBT/L after the same period. Male‐female couples and females that had been group‐mated but were isolated from males during the experiment (isolated ...
