If fertilisation does not occur, the corpus luteum regresses and the levels of oestrogen and progesterone fall. However, if fertilisation does occur, the corpus luteum is maintained. Regression of the corpus luteum is prevented by the implanting blastocyst which secretes a hormone, human chorionic gonadotrophin (hCG). This occurs about a week after fertilisation. The structure of this hormone is similar to that of LH and it takes on the role of LH in maintenance of the corpus luteum. To do this, it binds to the LH receptor... 

Table 1.10. Some pharmaceutical substances originally isolated from animal sources. While some are still produced by direct extraction from the native source, others are now also produced by direct chemical synthesis (e.g. peptides and some steroids), or by recombinant DNA technology (most of the pol5 peptide products). Abbreviations hGH = human growth hormone FSH=follicle stimulating hormone hCG=human chorionic gonadotrophin HSA=human serum albumin HBsAg=hepatitis B surface antigen...

It is to be expected that these extremely widely used oral methods of contraception will eventually be replaced by luteinizing hormone analogs as antiovulatory agents, or possibly by immunological methods directed against human chorionic gonadotrophin (hCG), which has both LH and FSH activity. Prostaglandins also show promise, and reliable male contraception is also a future possibility.

In a study of the relevance of the serum concentration of human chorionic gonadotrophin in 849 IVF cycles there were no significant relations between hCG concentrations and the proportion of follicles yielding oocytes, the fertilization rate, blastulation rate, or the probabilities of embryo transfer, implantation, or clinical pregnancy (32). This result again stresses the desirability of using moderate doses of hCG, which seems to reduce the risk of ovarian hyperstimulation while maintaining efficacy.

Eu3+, Tb3+, Sm3+, Dy3+ complexes have different emission wavelengths with sharp peak profiles, which are suitable for multi-component immunoassay. Several Eu-Sm two-color time-resolved immunoassays have been reported. Since the sensitivity of Sm3+ chelates is not high compared to Eu3+ and Tb3+, Eu-Sm two-color assays are used for the simultaneous determination of a low concentration component (Eu) and a relatively high concentration component (Sm) in serum the assayed combinations are lutropin and follitropin, myoglobin and carbonic dehydratase, AFP and free (3-subunit of human chorionic gonadotrophin (Hemmila et al., 1987). Use of Eu-Tb is reported by Eriksson et al. (2000) for the simultaneous determination of human serum free and total PSA.
