ABSTRACT A stereoisomeric analogue of progesterone, 9β,10α-pregn-4-ene-3,20-dione (retro-progesterone) and a 6-dehydro derivative, 9β,10α-pregna-4,6-diene-3,20-dione (6-dehydro-retro-progesterone) were studied for their progestational activity in 26 artificial cycles induced in 17 amenorrhoic women.1 It was found that 6-dehydro-retro-progesterone is a highly potent orally active progestational agent in the human subject. Daily doses of 10 mg of this compound given orally for 10 days induced a definite secretory transformation of the endometrium. The histological appearance of the endometrium following treatment with this compound could not be distinguished from that seen in normal cycles. Both compounds studied were excellently tolerated; no toxic side-effects were observed.

3β,5,6β-Trihydroxy-5α-pregnan-20-one 3-pivalate (I) was converted into 3β,6β-dihydroxy-5-methyl-19-nor-5β-pregn-9-en-20-one 3-pivalate 5-acetate (II) under conditions of Westphalen rearrangement. Deoxygenation in the position 6β was effected by treatment of the corresponding 6β-thiobenzoate or thioimidazolide with tributyltin hydride. Progesterone analogues XII and XIII, prepared from the 6-deoxy compound IX, exhibit abortive activity.

In an effort to improve the quality of in vitro produced porcine embryos, the effect of progestagens — progesterone analogues — on the in vitro developmental competence of porcine oocytes was studied. A total of 1421 in vitro matured oocytes, from 4 replicates, were inseminated with frozen-thawed spermatozoa. Progestagens were added to late maturation and embryo cultures (10 IU/ml). Fertilisation success (pre-maturation, penetration, monospermy and efficiency) and nuclear maturation were evaluated. There were no differences among prematuration rates between groups (P = 0.221). Penetration rates were higher (P < 0.001) in the presence of progestagens (75.0%) as compared to the control (51.7%). However, no differences were observed in monospermy percentages (P = 0.246). The results indicated that supplementation with progestagens increased the efficiency of the in vitro fertilisation system (P < 0.001). An additional beneficial effect was observed in nuclear maturation with progestagens (P = 0.035). In summary, progestagen supplementation is an important factor to improve the in vitro fertilisation procedure.
