A thorough evaluation of underlying motives for a decision by patients to make use of artificial insemination by a donor as a possible solution for the problem of involuntary childlessness as result of the male factor, should be a necessary prerequisite for the use of this procedure. In such a situation, an external factor (semen of an anonymous donor) is introduced to a complex dyadic system which is particularly susceptible to emotional stress. The implications of various less conspicuous but extremely important motives in the behaviour of such patients are stressed.

Background: Infertility is defined as failure to conceive even after one year of regular, frequent and unprotected intercourse. Infertility can be attributed to male causes in approximately 25-40% cases, female causes in 40-50% cases, both in 10-20% and unexplained causes in 10-15% cases. Artificial insemination (Intrauterine Insemination) involves placement of processed sperms from husband (AIH – artificial insemination homologous) or from donor (AID – artificial insemination donor) into the female genital tract.Methods: Objectives of the study were to do sperm preparation to obtain normal good quality motile sperms, to perform intrauterine insemination using husband semen around the time of ovulation, to study factors responsible for successful pregnancy rates by this method. Out of 100 infertile females recruited for the study 34 underwent artificial insemination by IUI with controlled ovarian hyper stimulation. Sperms were washed by density gradient centrifugation or by a direct swim-up technique that does not involve centrifugation.Results: Overall pregnancy rate per patient for male factor infertility was 23.52%. None of the patients consented for more than three cycles of IUI. Maximum pregnancy was achieved in third cycle of IUI. Sperm motility >40% was related with pregnancy in 8 cases. Duration of infertility didn’t influence pregnancy rate. The majority of pregnancies were achieved in the age group of 25-29 years (50%). No pregnancy occurred with >15 years of infertility.Conclusions: This study concluded that intrauterine insemination after ovarian stimulation or controlled ovarian hyperstimulation is a successful and efficacious therapy for infertility.

Intermittent Lighting Improves the Efficiency of Artificial Insemination in Cage Housed Laying Hens Kavtarashvili A.Sh., Kolokolnikova T.N. Federal Scientific Center “All-Russian Research and Technological Poultry Institute” of Russian Academy of Sciences Omsk Agrarian Scientific Center Summary: The effects of different lighting regimes on the oviposition schedule, productive performance, and reproductive efficiency in cage housed laying hens of layer parental flock (Hisex White-R) were studied; the reasonable regime of artificial insemination (AI) under intermittent lighting is proposed. It was found that intermittent lighting regime 1L:4D:4L:1D:4L:10D compared to the constant lighting significantly alters oviposition schedule: under this regime 82.3% of all daily eggs were laid until 9 am (vs. 66.6% in control). This regime and AI at 10 am improved the productive and reproductive performance compared to control (constant lighting 16L:8D and AI at 12 am): mortality by 1.9%, egg production per initial hen by 3.8%, egg weight by 1.1%, percentage of eggs suitable for incubation by 1.9%, egg fertility by 0.9%, hatchability by 2.3%, hatch of chicks by 2.9%, feed conversion ratio (kg of feed per 10 eggs) by 5.3%, the expenses of electric energy for lighting (per 1000 eggs suitable for incubation) by 54.5%.

The effects of a transient doe-litter separation on plasma prolactin, FSH and oestradiol concentrations, as well as the effect on LH response to exogenous GnRH administered at the time of artificial insemination, were determined in nursing rabbits. The effects on fertility, and litter size after parturition, as well as litter survival after doe-litter separation, were also studied. Control does (n = 12) had free access to nursing, whereas biostimulated does (n = 12) were separated from their litters for 48 h before artificial insemination. Plasma prolactin concentrations were decreased 24 h after the doe-litter separation (P < 0.05). The response of prolactin to suckling reached 10 times the basal values measured on day 10 after parturition (P < 0.0001). Increased oestradiol concentrations were found during the 48 h after the doe-litter separation: at 0 h, before artificial insemination (P< 0. 0001), 1.0-2.0 h after artificial insemination (P < 0.001), at 2.5 h (P < 0.05), 3.0 h (P < 0.01), and at 3.5 h (P < 0.05) after artificial insemination. Exogenous GnRH administered at the time of artificial insemination caused a greater LH response in does previously separated from their litters during 48 h (P < 0.01). The transient doe-litter separation did not affect plasma FSH concentrations, fertility, litter size or litter survival. These results suggest that a transient separation of nursing does from their litters before artificial insemination results in a decrease in plasma prolactin concentrations that could promote growth of follicular waves, and high steroidogenesis activity, leading to increased oestradiol concentrations and inducing higher sensitivity of the pituitary gland to exogenous GnRH. These findings associated to the absence of suckling episodes would lead to higher LH response and, therefore, exert a major effect on fertility.
