“…Males and females were created by crossing two different pairs of four extraction lines isogenic for chromosomes II and III. The origin of these four unique lines (line numbers 112, 140, 234, and 348) is described elsewhere (41). One cross (234 male ϫ 140 female) produced F1 females for mating; the other pair (112 male ϫ 348 female) was used to produce males.…”

Male-derived accessory gland proteins that are transferred to females during mating have profound effects on female reproductive physiology including increased ovulation, mating inhibition, and effects on sperm utilization and storage. The extreme rates of evolution seen in accessory gland proteins may be driven by sperm competition and sexual conflict, processes that may ultimately drive complex interactions between female-and male-derived molecules and sperm. However, little is known of how gene expression in female reproductive tissues changes in response to the presence of male molecules and sperm. To characterize this response, we conducted parallel genomic and proteomic analyses of gene expression in the reproductive tract of 3-day-old unmated and mated female Drosophila melanogaster. Using DNA microarrays, we identified 539 transcripts that are differentially expressed in unmated vs. mated females and revealed a striking peak in differential expression at 6 h postmating and a marked shift from primarily down-regulated to primarily up-regulated transcripts within 3 h after mating. Combining two-dimensional gel electrophoresis and liquid chromatography mass spectrometry analyses, we identified 84 differentially expressed proteins at 3 h postmating, including proteins that appeared to undergo posttranslational modification. Together, our observations define transcriptional and translational response to mating within the female reproductive tract and suggest a bimodal model of postmating gene expression initially correlated with mating and the final stages of female reproductive tract maturation and later with the declining presence of male reproductive molecules and with sperm maintenance and utilization.accessory gland proteins ͉ reproduction ͉ reproductive tract ͉ sperm ͉ sexual conflict

“…Moreover, identification and examination of the relationships among genetic polymorphisms associated with different levels of sperm precedence and associated fertility components reveal significant male-female interactions 134 , 144 . These male-male and male-female interactions likely reflect the multiple interacting traits involved in both male and female fertility and might serve to maintain genetic variation and decrease potential inbreeding 144 , 145 (also see ref 146 …”

Among most animals with internal fertilization, females store sperm in specific regions of their reproductive tract for later use. Sperm storage enables prolonged fertility, physical and temporal separation of mating from fertilization and, when females mate with multiple males, opportunities for differential use of the various males’ sperm. Thus, stored sperm move within the female reproductive tract as well as to several potential fates – fertilization, displacement by other sperm or ejection by the female. Drosophila melanogaster is a leading model system for elucidating both the mechanisms and evolutionary consequences of female sperm storage and differential male fertilization success. The prominence of Drosophila is due, in part, to the ability to examine processes influencing sperm movement and fate at several biological levels, from molecules to organ systems. In this review, we describe male and female factors, as well as their interactions, involved in female sperm storage and differential male fertilization success.

“…More evidence comes from the Mediterranean orb-web spider Argiope lobata [62], and the Australian field cricket Teleogryllus oceanicus [12]. In other species, however, CFC against inbreeding is either absent or less consistent 25, 63, 64. How can we explain this discrepancy?…”

Cryptic female choice (CFC) represents postmating intersexual selection arising from female-driven mechanisms at or after mating that bias sperm use and impact male paternity share. Although biologists began to study CFC relatively late, largely spurred by Eberhard’s book published 20 years ago, the field has grown rapidly since then. Here, we review empirical progress to show that numerous female processes offer potential for CFC, from mating through to fertilization, although seldom has CFC been clearly demonstrated. We then evaluate functional implications, and argue that, under some conditions, CFC might have repercussions for female fitness, sexual conflict, and intersexual coevolution, with ramifications for related evolutionary phenomena, such as speciation. We conclude by identifying directions for future research in this rapidly growing field.
