In none of the previous publications is there a mention of "that the compounds are capable of regulating meiosis. The content of the previous publications is incorporated as a reference. Meiosis is the unique and final event of the germ cells on which reproduction is based. Meiosis comprises two meiotic divisions. During the first division, the exchange between maternal and paternal genes takes place before the pairs of chromosomes in the two daughter cells are separated. These contain only half the amount (ln) of chromosomes and DNA 2c. The second major meiotic division proceeds without DNA synthesis. Therefore, this division results in the formation of aploid germ cells only with DNA.
The meiotic phenomena are similar in male and female germ cells, but the protocol in time and the processes of differentiation which lead to the ovum and sperm differ profoundly. All female germ cells enter the prophase of the first meiotic division at the beginning of life, often before birth, but all are suppressed as oocytes later in the prophase (dictiato state) to ovulation after puberty. Therefore, from early life, females have an accumulation of oocytes which is extracted until the accumulated is finished. Meiosis in women is not complete until after fertilization, and results in only one egg and two abortive polar bodies per germ cell. In contrast, only part of the male germ cells enter meiosis from puberty and leave in the pluripotent population of the germ cells during life. Once started, meiosis in male cells is carried out without significant delay and produces 4 sperm. Little is known about the mechanisms which control the onset of meiosis in men and women. In the oocyte, new studies indicate that follicular purines, hypoxanthine or adenosine, may be responsible for meiotic suppression (Downs, S.M. et al., Dev Biol 82 (1985) 454-458).; Eppig, J. J. et al. Dev Biol 119 (1986) 313-321; and Downs, S.M. Mol. Reprod Dev 35 (1993) 82-94). The presence of a diffusible meiosis regulatory substance was first described by Byskov et al. in a fetal mouse adrenal gland culture system (Byskov, A.G. et al., Dev Biol 52 (1976) 193-200). A meiosis activating substance (MAS) is secreted by the fetal mouse ovary in which meiosis is occurring, and a substantial meiosis avoidance (MPS) of the morphologically differentiated testes is released with resting non-meiotic germ cells. It has been suggested that the relative concentrations of MAS and MPS regulated at the beginning suppress and reassume meiosis in the male and female germ cells (Byskov, AG et al in The Physiology of Reproduction (eds. Nobil, E. and Neill , JD, Raven Press, New York (1994).) Clearly, if meiosis can be regulated, reproduction can be controlled.A recent article (Byskov, AG et al., Nature 374 (1995), 559-562) describes the isolation from bull testes and human follicular fluid from certain sterols that activate oocyte meiosis Unfortunately, these sterols are rather labile and their use to find interest would therefore be greatly facilitated if compounds were available more stable meiosis activators.
Compounds that are known to stimulate meiosis and are different from the compounds claimed in the present application are described in WO 96/27658. The compounds described herein have advantages compared to the known compounds.

The compounds of the present invention will influence meiosis in oocytes as well as in male germ cells. The existence of a meiosis-inducing substance in nature has been known for some time. However, until recently the identity of the substance or substances inducing meiosis was unknown. The prospects of being able to influence meiosis were several. According to a preferred embodiment of the present invention, a compound of claim 1 or an ester thereof can be used to stimulate meiosis. According to another preferred embodiment of the present invention, a compound of the claim may be used. 1 or an ester thereof to stimulate meiosis in humans. Therefore, the compounds of claim 1 and the esters thereof are promising as new fertility regulating agents without the usual collateral effects on somatic cells which are known from the hormonal contraceptives used up to now which are based on estrogen and / or gestagens. For use as a contraceptive agent in women, a meiosis-inducing substance can be administered in a manner that prematurely induces meiosis resumption in oocytes while still in the growing follicle, before the gonadotropin ovulatory peak occurs. In women, the resumption of meiosis can be induced, for example, a week after the preceding menstruation has ceased. When ovulating, the resulting oocyte oocytes later are more likely to not be fertilized. It is not likely to affect the normal menstrual cycle. In this regard it is important to note that the progesterone biosynthesis in cultured human granulosa cells (somatic cells of the follicle) are not affected by the presence of a meiosis-inducing substance while the estrogens and progestins used in the hormonal contraceptives used so far do not have an adverse effect on progesterone biosynthesis. According to another aspect of this invention, a meiosis-inducing substance of claim 1 or an ester thereof can be used in the treatment of certain cases of infertility in females, including females, by administration to the same females who, because to insufficient own production of meiosis activating substance, are unable to produce mature oocytes. In addition, when performing in vitro fertilization, better results can be obtained when a compound of claim 1 or an ester thereof is added to the medium in which the oocytes are maintained. When infertility in males, including man, is caused by insufficient self-production of the meiosis activating substance and therefore a lack of mature sperm cells, the administration of a compound of claim 1 or an ester thereof can alleviate the problem. As an alternative to the method described above, contraception can also be obtained in females by administering a compound of claim 1 or an ester thereof which inhibits meiosis, so that mature oocytes are not produced. Similarly, male contraception can be obtained by administering a compound of claim 1 or an ester thereof which inhibits meiosis, so that mature sperm cells are not produced. The route of administration of compositions containing a compound of claim 1 or an ester thereof can be any route which effectively transports the active compound to its site of action. Therefore, when the compounds of this invention are to be administered to a mammal, it is conveniently provided in the form of a pharmaceutical composition which comprises at least one compound of claim 1 or an ester thereof in connection with a pharmaceutically carrier. acceptable. For oral use, such compositions are preferably in the form of capsules or tablets.
From the above, it will be understood that the administrative regime that is required will depend on the condition in question. Thus, when used in the treatment of infertility, the administration can be carried out once only, or for a limited period, for example until pregnancy occurs. When used as a contraceptive, the compound of claim 1 or an ester thereof should be administered continuously or cyclically. When used as a contraceptive for females and not taken continuously, it will be important to synchronize the administration in relation to ovulation.

EXAMPLES EXAMPLE 1 Test of colest-5-en-3/3, 4/3-diol as a meiosis activating substance in the oocyte test.
Animals Oocytes are obtained from immature female mice (C57B1 / 6J x DBA / 2J hybrids Fl, Bomholtgaard, Denmark) weighing 13-16 grams, and kept under controlled illumination and temperature. The mice received intraperitoneal injection of 0.2 ml of gonadotropins (Gonal-F, Serono, Solna, Sweden, containing 20 IU of FSH, alternatively, Puregon, Organon, S ords, Ireland containing 20 IU of FSH) and 48 hours later. animals were sacrificed by cervical dislocation.
Collection and culture of oocytes The ovaries were removed and oocytes were isolated in Hx medium (see below) under a stereomicroscope by manual rupture of the follicles using a pair of 27-gauge needles. The spherical oocytes showing intact germinal vesicle (GV) are divided into oocytes enclosed in clusters (CEO) and naked oocytes (NO) and were placed in minimal essential medium ce (ce-MEM without ribonucleosides, Gibco BRL, Cat. No. 22561) supplemented with 3 mM hypoxanthine (Sigma Cat. No. H-9377), human serum albumin 8 mg / ml (HSA, State Serum Institute, Denmark), 0.23 mM pyruvate (Sigma, Cat. No. s-8636), 2 mM glutamine (Flow Cat. No. 16-801), 100 IU / ml of penicillin and 100 μg / ml streptomycin (Flow, Cat No. 16-700). This means is designated Hx medium. The oocytes were rinsed three times with medium with half Hx and the oocytes of uniform size were divided into groups of CEO and NO. CEO and NO were grown in multiple 4-well plates (Nunclon, Denmark) in which each well contained 0.4 ml of Hx medium and 35-45 oocytes. A control was always run (ie, 35-45 oocytes cultured in Hx medium without the addition of test compounds (together with the test cultures, which were made with different concentrations of the compounds to be tested, as indicated in the following tables, the cultures were carried out at 37 ° C and 100% humidity with 5% CE02 in air.The culture time was 22-24 hours.
Oocyte examination At the end of the culture period, the number of oocytes with germinal vesicle (GV) or germinal vesicle rupture (GVB) and polar body acylos (PB) is counted using a stereoscopic microscope or an inverted microscope with differential interference contrast equipment . The percentage of oocytes with GVB per total number of oocytes and the percentage of oocytes with PB per total number of oocytes is calculated in the test cultures and compared with the control culture.
Activation of meiosis in oocytes using colest-5-en-3ff, 4/3-diol. Compound source: Steraloids Inc., Wilton, NH, USA, Cat. No. C 6410, Batch No. L1066. The results are provided in the following table: DO NOT: CEO: As evident from the table, 5-en-3 / 3,4 / 3-diol induces meiosis in oocytes both nude and enclosed in clusters when cultured in vitro.
EXAMPLE 2 Test of meiosis inhibitory substances in the oocyte test.
Germ cell vesicle (GV) oocytes are obtained from female mice treated with immature FSH using the same methods described in Example 1 (see above). The oocytes are moistened three times in Hx medium and oocytes of uniform size are divided into the CO and NO groups. It was previously shown that 4,4-dimethylcholest-8, 14, 24-trien-3/3-ol (FF-MAS) induces meiosis in CEO and NO in vitro (Byskov, AG et al., Nature 374 (1995) 559 -562). CEO and NO were grown in Hx medium supplemented with 0.7-7.0 μM FF-MAS in co-culture with the test compounds in different concentrations in multiple four-well containers (Nunclon, Denmark) where each well contained 0.4 ml of Hx medium and 35-45 oocytes. One control (ie, 34-45 oocytes cultured in Hx cgue medium containing FF-MAS without addition of test compounds) always runs simultaneously with the test cultures, which are supplemented with different concentrations of the compounds that are to be try. The test results for the inhibition of meiosis in oocytes using colest-5-in-3/3, (22R) -diol (in the following referred to as "22R") is given in the Table below: DO NOT CEO: As is evident, from the tables, 22R antagonizes the resumption of meiosis induced by FF-MAS in a dose-related manner. This modality can be covered in other ways or it can be carried out in other ways without departing from the spirit or essential characteristics of it. The present description should therefore be considered in all its illustrative and non-restrictive aspects, the scope of the invention is indicated by the appended claims, and all changes which are within the meaning and scope of equivalence are encompassed by the same. .
