Intrauterine insemination with frozen sperm increases pregnancy rates in donor insemination cycles under gonadotropin stimulation

Effect of Female Body Weight on Efficiency of Donor AI

“…These changes in body mass almost always induce anovulatory conditions [2]. Arti®cial insemination with frozen donor sperm is useful in infertile couples in case of the husband's infertility [10,12]. In Hungary insemination was ®rst used by the Health Minister in 1981 and was modi®ed in 1988 by the Minister of Health and Social A airs for the sake of preventing the spread of AIDS.…”

Measuring outcomes in fertility trials: can we rely on clinical pregnancy rates?

“…We found discordant outcomes between pregnancy and live birth in eight studies (21)(22)(23)(24)(25)(26)(27)(28), see Table 2. In these studies, the ORs of the treatment and control groups were in agreement with each other, but one of the ORs (treatment or control) was not statistically significant.…”

“…Fertility outcome can be better predicted with sperm motion characteristics of a frozen-thawed specimen following insemination (24,25). The relationship between sperm motion characteristics and pregnancy rates using fresh and frozen sperm is conflicting (16)(17)(18)(19)22,(26)(27)(28)(29)(30). In subfertile patients, pregnancy rates are highly correlated with velocity, linearity, motility, or sperm concentration (14,15,31).…”
