Characterization of the HLA antigens present on lymphocytes has become an important procedure in paternity testing. This paper presents data on two cases in which the HLA antigens exhibited by the mother, child and alleged father were consistent with paternity but where the other genetic markers clearly showed exclusion of paternity. The use of HLA data alone to calculate probability of paternity in these two cases produced misleading figures. Caution must be exercised in using HLA results to calculate the probability of paternity, especially when there is reason to believe that the alleged and natural fathers are relatives.

External female genital mutilation (EFGM) is a type of traumatic mating in which males damage female genitalia, resulting in the loss of female re-mating ability. This study examined whether sexual conflict underlies EFGM by examining the possible female reproductive costs from the decreased number of matings in spider, . The female typically receives sperm from a male twice during a mating bout.

New paternity has been related to placenta-associated complications in pregnancy. We evaluated whether a lack of earlier pregnancies or deliveries with a current father are associated with the pregnancy, prenatal, and early neonatal outcomes after controlling for the most common maternal confounders in prospective birth cohort study. An online questionnaire was used to survey 4459 pregnant women from the Kuopio Birth Cohort in their third trimester.

Background: Posterior urethral valves (PUVs) represent the most common cause of male congenital lower urinary tract obstruction, often responsible for renal dysplasia and chronic renal failure. Despite recent improvements in patients' outcomes thanks to prenatal ultrasound early diagnosis, PUVs can still impact sexual function and fertility. This study aims to review the available evidence on fertility in PUV patients, examining paternity rates and semen parameters.
View Article and Find Full Text PDFOlfaction can aid individuals in finding genetically compatible mates in many animals, while high levels of mixed paternity may result from a limited ability to evaluate their mate's genetic profile against their own before mating. To test this suggestion and explore if olfaction may indeed influence mating patterns in birds, we combined published measures of olfactory ability with data on genetic mating pattern in the same species, across a phylogenetically broad range of species. We used three measures of olfaction: (1) olfactory bulb diameter, (2) olfactory bulb volume and (3) number of olfactory receptor genes (148, 134 and 48 species, respectively).
